Distinctive Performance

TS -590 S
HF/50 MHz ALL MODE TRANSCEIVER

Uncover the Hidden

The TS-590S marks a bold new chapter in Kenwoods proud history of manufacturing high-performance transceivers. Featuring a narrow-band Roong Filter the TS-590S signicantly reduces interference from unwanted signals, which results in excellent RX performance revealing signals that would be hidden to lesser rigs. With IF AGC based on advanced DSP technology, Kenwood has essentially redened HF performance. Built to satisfy the most demanding DXer, this high-performance HF transceiver takes Amateur Radio to the next level continuing the Kenwood tradition of operating ease and rugged reliability.

Superb RX Performance: Excellent Dynamic Range Even with Powerful Off-frequency Interference!
Thanks to a narrow-band Roong Filter and dedicated 1st Mixer, this new transceiver offers the best dynamic range in its class to handle adjacent unwanted signals.

Reciprocal Mixing

To measure the level of reciprocal mixing, an off-channel signal is mixed with the output of a signal generator, which is then varied until the unwanted signal can be detected as noise. The higher the gure, the less noise will be generated by adjacent interference, allowing undisturbed reception.
Powerful 500 Hz / 2.7 kHz Roong Filter
On 15, 20, 40, 80 or 160 meters, the TS-590S employs down conversion* for the rst IF (11.374 MHz). Having the 1st Roong Filter (6 kHz BW) directly after the Mixer enhances the noise blankers ability to deal with adjacent off-frequency signals. What really determines RX performance is the 2nd Roong Filter, after the post amplier. The TS-590S comes equipped with a 500 Hz and 2.7 KHz BW 6-pole MCF. This results in superb dynamic range when adjacent signals are present, performance that was not previously possible using up conversion. So even when an interfering signal approaches the target frequency, a virtually at dynamic range is maintained. Even with strong adjacent interference, you can capture a clear signal.

Wide Range of Features Thanks to 32-bit Floating-point DSP
In addition to basic functions such as AGC, digital IF lters, detection and demodulation, a wide range of features including noise reduction and IF notch are all implemented with the latest algorithms.
Advanced AGC with digital signal processing from the IF stage onward
The TS-590S employs DSP from the IF stage onward. Kenwood was the rst to offer DSP-based IF AGC in an Amateur radio (TS-870) and this DSP technology has been further enhanced for the TS-590S, resulting in the development of a unique approach to IF AGC. It is possible to apply level-optimized AGC even for signals that slip between the Roong Filter and the nal IF passband. You can be condent of optimum operation at all times, without having to think about the Roong Filter bandwidth. Gain control performance has been greatly improved for the target signal in the nal IF passband (RX band). This results in in-band IMD (intermodulation distortion) characteristics on a par with those of top-of-the-line transceivers. You can enjoy superb RX with next-generation Kenwood sound.
Texas Instruments TMS320C6726B
*For 1.8/3.5/7/14/21 MHz Amateur bands, when receiving in CW/FSK/SSB modes down conversion is selected automatically if the nal passband is 2.7 kHz or less.
DDS offers superb Carrier to Noise ratio characteristics, signicantly cutting noise generated by adjacent unwanted signals.
For the 1st local oscillator frequency, instead of employing conventional PLL/VCO, the output of a DDS (Direct Digital Synthesizer) is supplied directly to the following Mixer. When down conversion is active, the oscillator frequency is lower than it is with up conversion, so the output boasts even better C/N (Carrier to Noise ratio) characteristics and a desirable level of reciprocal mixing.
I IF auto-notch* & manual notch**

Automatic and manual notch are both implemented at the IF stage. By removing a powerful interfering signal with a notch lter, you can capture a weak target signal. With the IF auto-notch, notch frequency automatically tracks the beat frequency. The notch lter has such sharp characteristics that it is not possible to adjust it manually. Manual I IF Auto Notch notch, however, offers not only manual adjustment of the notch frequency, but also the choice of either normal or wide attenuation to suit the type of interference being encountered.
Extensive interference/noise removal features
Adjustable IF lter passband
By adjusting the DSP lter passband, you can tailor interference removal to suit your needs. This provides slope tuning in SSB/AM/FM modes, and bandwidth width/shift control for CW/FSK/SSB-DATA communications.

I Slope Tune

By adjusting HI/LOW cut, it is possible to avoid interference on one or both sides of the target signal.
*Available only in SSB mode. **Available in SSB/CW/FSK modes.
I Analog & Digital noise blanking (NB1 / NB2)
In addition to the analog noise blanker (NB1), which has a proven track record for eliminating weak noise, this transceiver is equipped with a newly developed digital noise blanker (NB2). Just pick the blanker which is more effective for the type of noise encountered and the RX conditions. NB1 offers stable noise suppression independent of RX bandwidth because, during down conversion, the noise that has passed through the 1st Roong Filter (NB lter) is fed to the NB circuit. The NB2 employs a newly developed envelope tracking method, making it effective against noise that dees tracking by an analog noise blanker.

I SHIFT

If the interference is on one side only, you can shift the central frequency without changing bandwidth.

I WIDTH

You can also avoid an adjacent unwanted signal by narrowing the passband.
I DSP noise reduction (NR1 / NR2)
In addition to conventional NR1 and NR2, NR1 now employs a newly developed spectral-subtraction approach that is specially designed to remove noise in speech modes. The optimum noise reduction method is applied for each RX mode.

Options and defaults for each mode (default settings in bold)

SSB mode

LOW CUT: 0, 50, 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000 Hz HI CUT : 1.0, 1.2, 1.4, 1.6, 1.8, 2.0, 2.2, 2.4, 2.6, 2.8, 3.0, 3.4, 4.0, 5.0 kHz

CW mode

WIDTH SHIFT : 50, 80, 100, 150, 200, 250, 300, 400, 500, 600, 1000, 1500, 2000, 2500 Hz : 300 Hz to 1 kHz (50 Hz steps)

SSB-DATA mode

WIDTH SHIFT : 50, 80, 100, 150, 200, 250, 300, 400, 500, 600, 1000, 1500, 2000, 2500 Hz : 1000, 1100, 1200, 1300, 1400, 1500, 1600, 1700, 1800, 1900, 2000, 2100, 2210 Hz
AM mode (AF lter for LOW cut)
LOW CUT: 0, 100, 200, 300 Hz HI CUT : 2.5, 3.0, 4.0, 5.0 kHz

FSK mode

WIDTH : 250, 500, 1000, 1500 Hz
G NR1 Spectral-subtraction noise reduction has been developed with a focus on improving speech clarity for weak SSB signals. Thanks to this advanced technology, which makes use of the processing power of the 32-bit oating-point DSP, you can capture a target signal that is swamped by I Noise Reduction noise, without suffering any NR1: Noise level is estimated and that loss in quality. For the alone is subtracted, thus emphasizing the target signal. non-speech modes (CW/FSK), a line enhancer offers tried and true noise reduction. Whichever method is used, the degree of attenuation can be adjusted smoothly. G NR2 (SPAC) Kenwoods original NR2 is SPAC-based noise reduction that extracts a periodic signal. SPAC is ideal for CW operations as it can suppress noise at the same frequency as the target signal. You can adjust correlation time I Noise Reduction in 2 ms increments from 2 ms NR2: SPAC to 20 ms (10 steps). NR2 is not available for FM.

FM mode (AF lter)

LOW CUT : 0, 50, 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000 Hz HI CUT : 1.0, 1.2, 1.4, 1.6, 1.8, 2.0, 2.2, 2.4, 2.6, 2.8, 3.0, 3.4, 4.0, 5.0 kHz
I Simple IF lter A/B switching
You can, for example, set Filter A for a wide passband, and Filter B for a narrow passband. When searching for a particular station during CW operations you can then use the Filter A, switching to the narrower Filter B once communications are initiated. In this way, you can easily switch between 2 preset DSP lters as needed.
I Beat cancel (BC1 / BC2)
Whereas IF auto notch is I Beat Cancel effective against a single, Multiple beats can be cancelled. powerful beat, the beat cancel feature comes into its own when there are multiple, relatively weak beats. Choose BC1 to remove weak and/or continuous beat interference, and BC2 to handle intermittent beat, like that of a CW signal. Since this can be used in conjunction with IF auto notch, even more effective beat cancellation is possible. (SSB/AM/FM only)
I Beat Cancel OFF I Beat Cancel ON

I Optional TCXO

The TCXO (temperature compensated crystal oscillator), which is available as an option, ensures superb frequency stability (0.5ppm) throughout a wide temperature range, from -10C to +50C.

I Drive output (including 135 kHz band)
The DRV terminal provides external access to the TX drive output (approx. 0 dBm). This is not just handy when a transverter is attached: the main antenna terminal cannot be used for transmission on the 135 kHz band, but this DRV terminal lls that need. Convenience is further enhanced when combined with the dedicated RX antenna terminal.
Note: A separate license r the 2200 meter band may be required.
I Speech processor (SSB/AM/FM)
The speech processor enhances the clarity of messages for the receiving station by raising average TX power. And as well as adjusting compression level, you can switch between soft and hard modes.
I Adjustable TX lter (SSB/AM)
The TX lter passband is switchable. Since the high-pass and low-pass cut-off frequencies can be switched independently, you can have ne control over lter operation.
High-reliability TX Section for a High-quality Signal
Kenwoods attention to detail is evident in both TX and RX performance.
I TX equalizer (SSB/AM/FM)
The equalizer offers at (default), high boost (2 types), Formant pass (to minimize extraneous sounds), bass boost (2 types), conventional and user settings (using the ARCP-590). It is possible to adjust frequency characteristics to suit the voice quality and microphone characteristics on the transmitting end.
Stable operation guaranteed. Designed for high reliability.
I 100 W heavy-duty design
The cooling system features a pair of 60 x 60 mm fans, the same size as on the previous model. Having two fans provides sufcient air ow at low rpm, ensuring quiet operation. Meticulous attention has been paid not only to the fans and motors but also to the size and shape of the intake/exhaust vents as a comprehensive approach to noise reduction. The aluminum die-cast chassis is combined with a large heat sink to enhance heat dissipation efciency, minimizing the rise in temperature in the nal section during continuous TX sessions. This heavy-duty design is capable of withstanding long hours of operation under grueling conditions typical of contests or DXpeditions.

I TX monitor

This outputs the TX audio via the speaker allowing you to check your own sound quality.

I Other TX features

VOX function (adjustable gain, selectable delay time) Adjustable TX power output Adjustable MIC gain Adjustable CAR level

Extensive CW Support

I CW auto tune
With just the press of a button, you can automatically zero in on a target frequency for CW reception. During RIT operations, it will also tune in to the RIT frequency.
I Built-in automatic antenna tuner (compatible with 5 MHz band)
The preset-type automatic antenna tuner enables quick band changing and can even operate when the TS-590S is receiving. When the TX frequency changes, the preset data (stored separately for each antenna band) is loaded into the antenna tuner circuit to ensure that optimum matching is rapidly achieved without having to retune.
I 2 key terminals on rear panel
Thanks to both an electronic keyer (built-in) paddle terminal and a separate one for an external keyer, PC keying is possible even when a paddle is connected.

I Other CW features

Kenwood Sky Command II

The Kenwood Sky Command System (KSS) effectively puts an HF transceiver in your hand, allowing you to relax in your backyard while controlling the TS-590S in your shack. Or you could be sitting at a baseball game while operating the HF transceiver safely installed in your car. Kenwood Sky Command II has the added convenience of LCD conrmation of HF frequency. Its not just freedom youll enjoy: KSS is simple and intuitive, yet amazingly powerful. Once the Transporter (TH-D72* or TM-D710A) has been wired to your TS-590S HF transceiver, all you need to is the second handheld (the Commander). The Commander transmits control signals to the Transporter, which also relays your voice to the HF radio. In return, HF signals are transmitted back to the Commander. This system allows you to transmit and receive HF signals, set frequencies, switch memory channels, and much more all from your handheld transceiver. Kenwood Sky Command II enables full-duplex operation, adding some extra features that further enhance functionality. For example, you can conrm HF frequency visually on the LCD panel of the Commander. Control is effected via TNC (AX.25), and now even more HF functions are accessible: XIT, mode switching (USB, FM, etc.), split-frequency operations on/off, memory shift, and frequency step selection. In addition, once every 10 minutes, the Transporter will send out its pre-programmed call sign via CW.

**Kenwood Sky Command II uses a pair of TH-D72* and/or TM-D710A transceivers.

1.2 Down Conversion

Figure 1-2 Block diagram: Down Conversion
Figure 1-2 describes the circuit configuration around the first mixer of the down-conversion path, showing the relationships between frequencies upon receipt of a 14 MHz signal. The signal from the antenna passes the RF BPF or LPF (as a receive LPF, it divides the frequency band of 30 kHz to 60 MHz into 12 ranges) and RF Amp (or bypasses it) to be sent into the first mixer. Because in the first mixer section, a different mixer is used for the up conversion and down conversion respectively, the suitable mixer is selected according to the conditions.
Figure 1-3 Receiver Mixer Circuit
The receiver mixer circuit is a quad mixer consisting of four 2SK1740 JFETs. The mixer circuit achieves superior characteristics thanks to the revision of I/O port matching and the optimization of biases. With the signal provided by the first local oscillator, the RX signal is converted to 11.374 MHz (first IF frequency). The converted RX signal passes the first roofing filter of pass bandwidth 6 kHz and in the subsequent stage the signal is moderately amplified by the post amplifier, and sent into the second roofing filter. Part of the signal is also sent to the noise blanker. The role of the first roofing filer is to limit the bandwidth for the sake of the noise blanker. We have selected a pass bandwidth of 6 kHz that does not affect pulse noise. Besides, by setting the intercept point of the post amplifier higher than that of the mixer, the deterioration of the two-tone characteristics is minimized within the pass bandwidth. For second roofing filters, two 6-pole MCFs of 500 Hz and of 2.7 kHz respectively are equipped as standard at the time of purchase of your transceiver. Which filter is used is automatically determined according to the final pass bandwidth, i.e. depending on the conditions including the bandwidth selection made with WIDTH or LO CUT/ HI CUT controls on the front panel. For example, in CW or FSK mode, if WIDTH is 500 Hz or less, the 500 Hz filter is selected and if WIDTH is 600 Hz or more, 2.7 kHz filter is selected. In SSB mode, if the difference between the HI CUT and LO CUT frequencies is 2.7 kHz or less, the 2.7 kHz filter is selected and if the combination produces exceeds a difference of 2.7 kHz, the up-conversion path is automatically applied. (In SSBDATA mode, if WIDTH is 500 Hz or less, the 500 Hz filter is selected.) In AM and FM modes, because the pass bandwidth of the down conversion path is too narrow, the signal is received with the up conversion path. These operations are used in the amateur radio bands of 1.8 MHz, 3.5 MHz, 7 MHz, 14 MHz and 21 MHz, and for other amateur radio bands including WRC bands, and for other frequency ranges of general coverage receiving, up conversion is used regardless of the mode and pass bandwidth. (Since this switchover is determined by the CPU taking various conditions into its criteria, the conversion path cannot manually be selected.)

The final amplifier of the TS-590S is a push-pull amplifier using two pieces of RD100HHF1 MOSFET from Mitsubishi Electric Semiconductor (Pch 176.5 W). The drive amplifier also uses an RD100HHF1 MOSFET and the pre-drive amplifier employs an RD06HHF1 MOSFET and they, despite being 13.8V final circuits, amplify the signal reasonably in a stable and continuous manner with low distortion. Figure 2-1 shows the graph of IMD characteristics and Figure 2-2 shows the graph of harmonic spurious characteristics. Superior distortion characteristics and clean signals are acquired in this way.
Figure 2-1 Transmit IMD Characteristics
Figure 2-2 Transmit Spurious Characteristics
2.2 High-speed Relay-controlled Antenna Tuner
TS-590S has a built-in high-speed relay-controlled antenna tuner that was first employed in the TS-570S. In contrast to the variable capacitor type antenna tuner, it employs a small and lightweight relay to achieve a sufficient matching range and a fast tuning operation with digital control. The control speed has been further accelerated over previous models. When you return to a previously used operating band or frequency, the antenna tuner easily and quickly re-tunes.

2.3 REMOTE Connector

The transceiver has a REMOTE connector that has the same pin assignment and specifications as on previous models. Pin 6 is the ALC terminal. When you use a linear amplifier or transverter, we recommend you connect the external accessory device to the ALC terminal in order to control the output to be within an appropriate range. The ALC signal is a signal to shift the voltage in the minus direction (in Kenwoods devices) when the output level requires regulation to satisfy the requirements of the external accessory device. Generally external accessory devices have a VR for adjusting the voltage. In the TS-590S, a negative voltage (approximately -10 V) is applied to the ALC terminal to decrease the internal gain. As well, for the purpose of controlling a linear amplifier and other external device, the transceiver is equipped with a relay output terminal and an RL terminal (Pin 7) to which an approximately 12 V voltage is output. The relay output and RL terminal output are coordinated with internal controls and can be adjusted in the linear amplifier control setting menu No. 53 (HF bands) or No. 54 (50 MHz band). Table 2-1 describes the possible settings of the menu, and Figure 2-3 and Figure 2-4 provide the timing charts. If using equipment that is not designed for full break-in and requires a delay for internal switchover, such as TL-922, select 3. In this way, you can increase the delay between the case when the transceiver is switched to transmit and the case when the signal is actually sent out. Note; however, if the full break-in setting is selected in CW mode (and if the delay time is set to FBK), the transmit start time cannot be delayed.

Figure 2-10 Output Characteristics of DRV Terminal at 136 kHz and -20 dBm

3 LOCAL OSCILLATOR

In the first local oscillator, instead of the conventional PLL/VCO system, a 14-bit DDS (direct digital synthesizer) is adopted to provide the output signal directly to the mixer. During the down conversion, the oscillator frequency is lower than that in up-conversion operation, and, therefore, the output has far better C/N (carrier-to-noise ratio) characteristics that contribute to superior reciprocal mixing*1 characteristics.
Reciprocal mixing: First, the signal sourced from a signal generator (SG) at a frequency far from the receive frequency is injected. Then, the output level of the signal generator is changed to measure the level at which the signal is detected as noise. The higher the value, the lower the noise that is produced due to adjacent undesired signals occurring and therefore quieter reception is possible.
Figure 3-1 Comparison: C/N Characteristics
Figure 3-1 is a graph to compare the measurement results of TS-590S and of TS-480S at 14.200 MHz. For example, at the 10 kHz point, if the receive frequency is 14.200 MHz, an unmodulated carrier signal of 14.210 MHz is supplied from a signal generator to the antenna terminal of the transceiver. In the TS-480S, if the output level from the signal generator reaches -45 dBm, the noise level starts to rise. However, in the TS-590S, you can see the noise level goes up if the signal sourced from the signal generator is raised to -25 dBm. Figure 3-2 shows a graph of C/N characteristics plotting the data measured at the TS-590Ss first local oscillator.

Figure 4-7 Clear Weak Signal by Eliminating Interference with Manual Notch Filter (from above, Disabled to be Enabled)
There are two settings on the manual notch filter: Normal and Wide. You can choose one of two bandwidths for the notch filter (Figure 4-8). For a simple beat frequency, Normal is effective. If there is an interfering SSB signal, or in the event the target signal is also trimmed by LO CUT/ HI CUT, a Wide setting of the Notch filter used in combination with LO CUT/HI CUT may be effective.
Figure 4-8 Results of Amplitude and Frequency Analysis of the Manual Notch Filter
The shifting of the notch frequency with the notch knob is not actually done by switching the notch filters depending on the knob position. In fact, within the DSP, the notch filter frequency is fixed and the frequency shift is made possible by altering the IF signal frequency. The auto notch filter inherited from the TS-2000S and the TS-870S also has been improved to deliver better capability to track the beat frequency. The enhanced notch filter has good effect even on a relatively weak beat signal. The auto notch filter is sharper, like a needle, than the manual notch filter and can minimize the impact of the notch on the audio.
4.3.4 Digital Noise Blanker (NB2)
Refer to 4.6.2 Noise Blanker NB2 (IF Processing).

4.4 Demodulation

For the demodulation of the RX signal in SSB, CW, FSK and SSB-DATA modes, we have employed the proven PSN (Phase Shift Network) design again. In the previous models (TS-2000S and TS-870S), the selection of the PSNs characteristics was interlocked with the passband setting of the IF filter, and when the passband is narrow, a PSN with a good sideband suppression was selected. On the other hand, on the TS-590S, the order of the PSN is decreased by tuning the PSN only to the opposite side band that was not fully removed by the digital IF filter. In this way, the low frequency range of the PSN stretches out substantially and the poor group delay characteristics in the lower frequency range, which is a drawback of a PSN, is also improved. As a result, the low range reaches farther with less attenuation than that reached in the previous models. In SSB mode, the digital IF filter has a setting of 0 Hz in LO CUT and this means the cutoff frequency is set to the carrier point so that the low frequency range can be stretched out maximally. Enjoy distinctly different audio from that of previous transceivers. The same demodulation process is used in SSB, CW FSK and SSB-DATA modes, except that the selection of PSN characteristics and of digital IF filters varies depending on the mode. In AM mode, an absolute value detection circuit is used for demodulation as in the previous models.

4.5 Modulation

Following is how the TX signal is processed. The audio signal captured from the microphone or an external terminal is first processed by the bandwidth-limiting filter, microphone gain control, speech processor or VOX, and then, in SSB and AM modes, the signal is modulated and output as an IF signal; in FM mode, a CTCSS tone signal is added. In CW mode, the waveform of the keying input is shaped and then the signal is multiplied by the modulating carrier to be transmitted as an IF signal. At the same time, the signal is multiplied by a carrier for monitoring to produce a CW sidetone. In FSK mode, the keying input is processed by a baseband filter for bandwidth limiting, and then the signal is processed by frequency modulation with the 24 kHz center frequency to obtain an FSK modulated wave. As in CW mode, for the purpose of monitoring, the audio center frequency based on the FSK tone frequency setting in the menu mode is processed by frequency modulation to obtain the monitoring audio. In SSB mode, the proven PSN design continues to be adopted for modulation. Unlike for demodulation, for modulation enough sideband suppression must be provided for the bandwidth of the modulation input. The characteristics of the PSN are designed to deliver sufficient suppression according to the characteristics of the bandwidth-limiting filter (Figure 4-9).
Figure 4-9 Opposite Sideband Suppression Characteristics of the PSN for SSB Modulation
The bandwidth-limiting filter for transmission that can be set in the menu mode is applied to SSB and AM modes, but in SSB mode the filter is made sharper at 3 kHz.
4.6 DSP-based Auxiliary Circuits (for RX)
4.6.1 Beat Cancel (AF Processing)
Beat cancel (BC), as its name implies, is designed to cancel unpleasant beat interference. Like NR1 (line enhancer), BC uses adaptive filter technology. With this technology BC tracks and cancels a beat signal just like shaping a band elimination filter. BC is especially effective when there are multiple beats that are equivalent to or lower in strength than the target signal. The adaptive filter can self-adjust its characteristics while tracking multiple beats and effectively cancel them.

5.11 Expansion of Voice Guide Function (Optional VGS-1 Required)
The optional VGS-1 voice guide and storage unit can be installed on the transceiver. The voice guide and audio recording function that are acclaimed by sight-impaired operators become available. The following are the details of the VGS-1 and new functions added for the current version.

Figure 5-7 VGS-1

Voice Guide Function
On the TS-590S, in addition to the conventional audio announcements, the readings of the multimeter (SWR meter, ALC meter and COMP meter) can be also announced. Also, by setting the auto announcement to be disabled in the menu mode, the announcements can be made only when the VOICE key (that is to be assigned to the PF key) is pressed.

Voice Storage Function

A maximum of 4 channels can be used for storing voice for transmission. This is a very convenient option for an operator who participates in a contest in SSB mode. (The CW message memory function is available on the transceiver and does not require VGS-1.) Channel 4 of the voice recording channels for transmission can be assigned for recording a received voice signal. Anytime upon a press of the [REC] key, you can store the voice signal received over the past 30 seconds in flash memory and replay the voice as required.
Hints and Tips What are the projections on the rear panel for? On the rear panel of the TS-590S, projections are placed near some connectors.
Figure 5-8 Projections on the Rear Panel
We have provided these guides to meet the demands from sight-impaired operators who wish to set up the transceiver without help from someone else. If two identical connectors are placed side by side, you can not tell them apart just by feeling them. The projections are provided so that the applications of the connectors can be easily distinguished. These projections will allow a sight-impaired person to understand the positional relationship of the connectors and to connect cables easily by feeling the rear panel with their fingers. Also, a transceiver is often placed on a rack and a user is sometimes forced to connect cables without seeing them. The projections will also help you in such a situation. This careful attention is also part of Kenwoods efforts for accessibility improvement based on easy operation. Projections are provided near the following connectors: DRV, RX, ANT, ANT1, and ANT2.

7.3 Main Control Knob

We have designed the main control knob located in the center of the front panel, focusing on easy handling and good appearance. For the encoder, a 250-pulse magnetic encoder is adopted, which enables the pulses are multiplied by 4 using software to produce 1,000 pulses per revolution so that a user can tune to the desired frequency smoothly. Each of the aluminum parts is machined with CNC (computerized numeric control) and treated with spin finish. We also paid careful attention to the color of the main control knob; we have colored the knob with a color alumite treatment. We made samples repeatedly until the desired color was finalized. The alumite color is adjusted to match the rubber color of the knob ring and the paint color of the front panel in order to express the integration and massiveness of the entire panel. Not only for the main control knob, easy handling was our priority when designing the sizes and locations of other controls (knobs and keys). We carefully studied the sizes and layout of the knobs so that a finger will not hit the adjacent knob when a user turns a knob. Though the TS-590S has a relatively compact front panel as an HF transceiver, the controls are positioned for comfortable operation.

8 EXPANSIVE APPLICATION SOFTWARE
8.1 Windows Related Software
This chapter describes the Windows related software to be used to control the TS-590S from a PC. Following are the Windows related software products that can be used with the TS-590S.
Table 8-1 Windows Related Software for TS-590S

Name ARCP-590 ARHP-590

Description This software enables control of the TS-590S from a PC. This host program is used on the host station PC when the TS-590S is remotely controlled over a network. The software is used in combination with ARCP-590. This VoIP software is to transfer the TX and RX audio signals when remotely controlling the TS-590S over a network.
Note: The software is composed of ARVP-10H and ARVP-10R.

ARVP-10

ARUA-10
This software enables use of the microphone and speaker of a PC in place of those on the TS-590S. It enables the audio signal from the PCs microphone to be transfered via USB audio and transmitted from the TS-590S. Also, the audio output of the TS-590S can be emitted from the PCs speaker via USB audio.

Caution: When the USB connector is used for input/output of the audio signal on the host station, ARUA-10 is not required neither.
8.3 New ARCP-590 (Amateur Radio Control Program for TS-590S) Freeware
ARCP-590 (Amateur Radio Control Program for TS-590S) is software enabling control of the TS-590S from a PC.
Figure 8-1 Main Window of ARCP-590
ARCP-590 is available free and can be downloaded from Kenwoods website. URLs from which ARCP-590 can be downloaded: http://www.kenwood.com/i/products/info/amateur/software_download.html As with ARCP-480 for the TS-480S, the new ARCP-590 program is designed to control virtually all of the functions on the TS-590S transceiver.
8.3.1 Basic Specifications Inherited from ARCP-480
The basic specifications of the ARCP-590 are inherited from ARCP-480 for the TS-480S. In addition, ARCP-590 conforms to the new functions of the TS-590S.

8.3.2 User Interfaces

ARCP-590 supports Japanese and English user interface languages. A user can use ARCP-590 in the language the user is the most familiar with. The ARCP-590 comes with a function to automatically connect to the TS-590S when the software is started. If you habitually control the TS-590S from a PC, the function saves the effort to establish a connection each time. To enable this function, from the Tool pulldown menu, select Setup and in the Setup dialog box, click on the Connect automatically at startup checkbox to activate. In addition to the tuning control method used in ARCP-480 for TS-480S, ARCP-590 has new methods to change frequency as follows: 1. Frequency change with the main knob 2. Frequency change with Tune up and Tune down buttons 3. Frequency change with MULTI/CH up and MULTI/Ch down buttons 4. Frequency change with the direct input mode 5. Frequency change with the mouse wheel 6. Frequency change by clicking on the frequency display section In method 1 and 2, you can now select the tuning step from the Tuning step dropdown list.
Caution: In the event you are using KSN over a network or you have selected a setting other than Preset from the Tuning Step dropdown list, the response may be slower. In such a case, select Preset. This is because the way to control the TS-590S differs in Preset and in other settings.
In method 5, by turning the mouse wheel, you can change the step selected from the MULTI/CH Step dropdown list. By turning the mouse wheel while pressing down the [Ctrl] key, you can change the step selected form the Tuning Step dropdown list (this function is available in ARCP-590 Ver. 1.01 or later). In ARCP-590, a status bar is added in the bottom part of the main window. You can check frequentlyused items in a single glance, such as modulation line, transmit output power, microphone gain, keying speed, connection destination, time in UTC and local time.

Figure 8-2 Status Bar

The ARCP-590 has newly adopted a listing by category in the menu function. The new listing by category as well as the conventional general listing allows quick access to the desired function.

Figure 8-3 Menu Function

The ARCP-590 enables a user to set the delay time for switching from transmit to receive in order to address the delay that occurs when using KNS over a network. Formerly, the last part of the transmitted voice was sometimes cut off when switching from transmit to receive due to the difference of delay time of control commands and of audio signals. In order to solve this problem, the timing to actually switch back to receive can be delayed for the time period specified in ARCP-590 after the user operates the switchover. From the Tool pulldown menu, select c. In the Setup TX Control dialog box of transmit control you can select delay time from the Switching the delay time from transmit to receive while the transceiver is connected to the network dropdown list for switching back from transmit to receive when controlling over a network connection.
8.3.3 KNS (Kenwood Network Command System)
As with ARCP-480 for the TS-480S, the ARCP-590 also enables control of the transceiver using KNS over LAN or the Internet. Install ARHP-590 program (explained later) on the host station PC to construct the system.
Figure 8-4 Conceptual Image of a KNS Configuration
In ARCP-590, the number of connection destinations that can be registered has been expanded from a maximum of 10 to 100. The ARCP-480 and ARHP-10 for the TS-480S are supplied with the VoIP function to send and receive voice over the network connection, but the VoIP engine is not compatible with newer Windows OSs. Thats the reason the VoIP function is excluded from the new ARCP-590 program. In order to use VoIP capability, construct a system using ARVP-10H and ARVP-10R (explained later) or generic VoIP software. KNS Welcome Message function is added so that the KNS host administrator can leave a simple message to a KNS client user; or a KNS client user to the another KNS client user. The KNS welcome message can be edited or deleted either from ARCP-590 or ARHP-590. In ARCP-590, select the Edit KNS Welcome Message from the Tool pulldown menu and you can edit or delete the welcome message in the Edit KNS Welcome Message dialog box. In ARHP-590, select the Edit KNS Welcome Message from the Tool pulldown menu and you can edit or delete the welcome message in the Edit KNS Welcome Message dialog box.
Figure 8-5 KNS Welcome Message
Refer also to TS-590S KENWOOD NETWORK COMMAND SYSTEM Setting Manual on the Kenwoods website.

Caution: You must comply with all radio and domestic laws, regulations and rules of the country or region where you are connecting with the KNS System via the Internet.

8.3.4 Visual Scan

ARCP-590 is capable of visually showing the location of the current RX frequency on the display and of shifting the current RX frequency to the center of the scan span. The scan center frequency and the scan span can be stored for each amateur radio band. It is ideal for checking the condition of respective bands for specified frequency ranges.

Figure 8-6 Visual Scan

Note: During the scan, the receive audio of the transceiver is muted.

8.3.5 Audio Equalizer

In ARCP-590, the setting of the audio filter can be configured with a graphic equalizer-type interface. ARCP-590 has 18 bands from 0 Hz through 5,100 kHz.

8.4.1 Basic Specifications Inherited from ARHP-10
The basic specifications of the ARHP-590 are inherited from ARHP-10 for the TS-480E. In addition, ARCP-590 is compatible with the new functions of the TS-590S.

8.4.2 User Interfaces

ARHP-590 supports Japanese and English user interface languages. A user can use ARHP-590 in the language the user is the most familiar with. In ARHP-590, a function to automatically run the program when Windows starts is added. Using this function, upon restart of the PC, ARHP-590 can be activated and a connection is made automatically. To enable this function, select Setup from the Tool pulldown menu and in the Setup dialog box, click on the Activating automatically when Windows starts checkbox.
ARHP-590 allows a user to check the operating status of ARHP-590 and TS-590S even after minimized. You can check the status of the power of the TS-590S (Power ON or Power OFF) and your connection and transmission statuses.

For details of Kenwood Network Command System, refer to 8.3.3. KNS (Kenwood Network Command System).
8.4.4 Disabling AF Gain Control from ARCP-590
ARHP-590 has a capability to disable the AF gain control from the ARCP-590. While AF gain is controlled from ARCP-590, the audio volume of the TS-590S may be adjusted in an unexpected way. Therefore, we have added a function to disable this control. To enable this function, from the Tool pulldown menu, select Setup and click on the Prohibits control of AF gain from ARCP-590 checkbox.
8.5 New ARUA-10 (USB Audio Controller) Freeware
We have released ARUA-10, the USB audio control software to allow the PCs microphone and speaker to be used in place those of the TS-590S. ARUA-10 is available free and can be downloaded from Kenwoods website. URLs from which ARUA-10 can be downloaded: http://www.kenwood.com/i/products/info/amateur/software_download.html Refer also to TS-590S USB Audio Setting Manual on the Kenwoods website.
Caution: For USB audio, time delay is unavoidable due to its operating principle. Therefore, USB audio cannot be used for a latencycritical application (e.g. operations in a contest or pileup where a quick response is essential). During the operation with KNS over a network connection, ARUA-10 is not required.

8.5.1 Basic Functions

If ARUA-10 and ARCP-590 are used in combination, you have only to connect the TS-590S and a PC with a single USB cable to use the microphone and speaker connected to the PC in place of those on the transceiver. To use ARCP-590 over a USB cable connection, the virtual COM port driver needs to be installed. If you use only ARUA-10 over a USB cable connection, the virtual port driver doesnt need to be installed. If you use the built-in USB sound function of the TS-590S only, the function runs on the Windows standard driver.

8.5.2 Operation

ARUA-10 bridges the TS-590Ss built-in USB sound function (USB audio device) and the sound device that controls the microphone and speaker on the PC. A voice signal from the microphone connected to the PC is input into the modulation input of the TS-590Ss USB audio device. The audio output of the TS-590Ss USB audio device is emitted from the PCs speaker.
Figure 8-10 Flow of the Audio Signal

8.5.3 Setup

Configure the necessary settings to use ARUA-10. Right click the ARUA-10 icon in the Windows task tray and select Device Setup in the menu and the Setup dialog box will appear. In the Device tab, you can set up the device to input/output the audio signal.

To connect ARVP-10R to ARVP-10H, after above setting is complete, click the Connect button in the main window. To disconnect ARVP-10R and ARVP-10H, click the Disconnect button in the main window.

8.6.6 Adjusting Volume

ARVP-10H and ARVP-10R have no function to adjust volume. Instead, use the volume mixer or volume control in Windows to adjust volume.
8.7 New Virtual COM Port Driver
To connect the TS-590S and a PC via a USB cable to control TS-590S, the virtual COM port driver needs to be installed on the PC. URLs from which virtual COM port driver can be downloaded: http://www.kenwood.com/i/products/info/amateur/software_download.html If you connect the TS-590S and a PC using an RS-232C cable, the virtual COM port driver does not need to be installed. Also, if you connect the TS-590S and a PC via a USB cable and you use only ARUA-10, the virtual COM port driver does not need to be installed either. If you use only the built-in USB sound function of the TS-590S, the function behaves using the Windows standard driver. To view the COM port number to which the virtual COM port driver has assigned the USB port of the TS-590S, open Windows Device Manager and check Port (COM and LPT). Locate the entry named Silicon Labs CP210x USB to UART Bridge (COMxx) and xx in the COMxx represents the COM port number assigned by the current virtual COM port driver. In the example of Figure 8-16, you can see the indication of Silicon Labs CP210x USB to UART Bridge (COM4). In this case, COM4 is the COM port number assigned by the current virtual COM port driver.
