HF/50/144/440/1200MHz

All-Mode, Multiband, Engineered for Excellence
Kenwoods new TS-2000/2000X/B2000 all-mode multibander may be compact, but its equipped with all the features you would expect to find in a top-of-the-line rig.
IF Digital Signal Processing
The TS-2000/2000X/B2000 is serious about digital signal processing. Kenwoods advanced digital technology converts analog waveforms into digital data in real-time, enabling such digital processing as IF filtering, slope tune, auto notch and AGC. IF-stage DSP on main-band transmit and receive including V/UHF bands allows the greatest range of control and unprecedented performance.

DSP Detection

IF-stage DSP means that the TS-2000/2000X/B2000 offers significantly lower distortion and higher quality detection in all modes. (FM: digital AF filter)

Digital Filtering

There is absolutely no need to purchase optional filters: digital IF filters are available for each mode (FM: digital AF filter), offering performance superior to anything possible with analog circuitry. When operating in SSB/FM/AM modes, this digital filtering enables both high- and low-cut frequency variance. Employing slope tune, you can thus cut out
noise with minimal effect SHIFT Desired on sound quality. In AM signal (CW) mode, the high-cut frequency can reduce interInterfering signal (SSB) ference by controlling the IF pass bandwidth useful for receiving shortwave broadcasts. In CW mode, the WIDTH funcWIDTH tion is supplemented by Desired center frequency shift, signal (CW) allowing adjacent signal Interfering interference to be tuned Interfering signal signal (SSB) (CW) out. The WIDTH function also provides noise reduction capabilities in FSK with 4 steps available: 250, 500, 1000 and 1500Hz. And thanks to AF-stage DSP, independent control of high-cut and low-cut frequencies (12 steps each) provides slope tune capability in FM as well.

IF Auto Notch

Since it is working with a DSP notch filter Beat digital signal, IF Auto Notch (main band, SSB mode) can provide Conventional notch filter slope extremely sharp filtering Target signal of carrier frequencies from broadcast and continuous beat sources. The interfering beat is removed far more accurately than in conventional analog systems, and Auto Notch will even track changes in the beat signal (tracking speed can be varied in 5 steps).
Hi-cut slope tune Interfering signal (SSB)
Lo-cut slope tune Desired signal (SSB) Interfering signal (CW)

IF AGC

The digital AGC circuit (main band only) delivers very fast release characteristics, surpassing even the best analog designs. You can select a custom release time (20 steps) for each mode, except FM.

AF Digital Signal Processing
DSP is also executed at the AF stage, offering Beat Cancel and CW Auto Tune functions. It also enables you to achieve remarkable noise reduction and apply custom enhancements to your transmitted voice.

Beat Cancel

Automatic Beat Cancel, available for the main band (SSB and AM modes), immediately eliminates multiple beats interfering with a desired signal. It works well in combination with IF Auto-Notch (SSB).

Beat Canceled

Noise Reduction
There are 2 types of noise reduction: LEM (NR1) and SPAC (NR2). LEM (Line Enhancer Method) available for all modes on the main band and FM/AM on the sub band automatically forms a filter shape around the target signal for a custom, dynamic noise reduction capability. The degree of enhancement can also be set manually for mainband use. The SPAC (Speech Processing/Auto Correlation) Line Enhancer Method Formed filter function utilizes a special staNoise Noise tistical/correlation algorithm to pull out weak signals that Signal are buried deep in noise. SPAC Method Although available for all Extract signal modes on the main band, its from the noise Noise Noise especially useful for tough CW conditions. The correlation time setting can be adjusted in 10 steps between 2ms and Signal 20ms.

Manual Beat Cancel
A new Manual Beat Cancel function, which operates as a manual AF notch, can be used in all modes though it is particularly effective in CW.

TX Audio Shaping
You have 3 ways to tailor audio quality with DSP: the TX/RX equalizer (SSB/FM/AM), TX filter bandwidth (SSB/AM), and speech processor (SSB/FM/AM). The TX/RX equalizer offers 4 frequency response settings on SSB, FM and AM: high boost for improved clarity, formant pass to minimize extraneous sounds, bass boost for stronger sound, and conventional mode for an analog sound. On SSB and AM transmit you can choose between 6 TX filter bandwidth settings according to your microphone and operating requirements. The speech processor works across three bands (SSB, FM and AM) for high compression and minimal distortion.

CW Auto Tune You no longer have to adjust the VFO while operating on CW CW Auto Tune does it for you automatically by adjusting the VFO to your preset pitch at the touch of a button.
High-duty Transmitter Section
This transceiver is the perfect choice for contesting, mobiling and FSK applications, delivering up to 100 (AM: 25) watts on HF/50/144MHz bands. Output is 50 (AM: 12.5) watts on the 440MHz band, and 10 (AM: 2.5) watts on 1200MHz*. But theres more than just power: the built-in TCXO ensures excellent frequency stability 0.5ppm (except in FM mode).

*Minimum output is 5 watts for HF/50/144/440MHz bands, 1 watt for 1200MHz.

CW Features

In addition to the new Auto Tune function, there is a full range of CW features. The full/semi break-in switching and delay time settings are fully adjustable. In semi break-in the delay time between key release and active receive mode can be set for between 50ms and 1000ms. When using VOX operation the delay time can be set for between 150ms and 3000ms. Other CW features include pitch control (400-1000Hz), side tone monitor with 10-step volume setting, DSP-based rise time adjustment, and CW reverse mode.
Built-in 1200/9600bps TNC
The simple 2-chip TNC is compliant with the AX.25 protocol for Sky Command and DX cluster tune.

Dual-Channel Watch

Provision of main and sub bands enables dual-channel watch. This all-mode multibander can simultaneously receive two frequencies, even on the same band, allowing such combinations as HF+V/UHF, VHF+VHF, UHF+UHF and VHF+UHF (the sub band is used exclusively for 144/440MHz reception on FM/AM). This means, for instance, that you can pick up local information on V/UHF while operating HF on the main band.

FSK Features

When operating in FSK mode, you can select shift frequencies (170, 200, 425 and 850Hz) and switch both KEY polarity and Hi/Low tones to suit your RTTY device. Additionally, the FSK reverse function lets you match transmission methods to the other party if necessary, for example changing the BFO frequency from LSB (normal) to USB (reverse).

Satellite Communications

Satellite operations are enhanced with the IF-DSP, 10 dedicated memory channels, Doppler effect frequency adjustment (manual) and the ability to choose either normal or reverse shift for the trace.

FM Features

As well as switchable Narrow/Wide deviation modes, the TS-2000/2000X/B2000 has built-in CTCSS functionality with 38 EIA-standard sub-tones settings plus 1750Hz tone burst. Other features include DCS (104 codes), both crossband and fixed-band repeater operation, and 1200MHz ALT.

Kenwood Skycommand System II Plus
The TS-2000/2000X/B2000 is fully equipped for Kenwoods Skycommand System II Plus. With just a handheld transceiver you can relax in your garden while DXing from your shack. Alternatively, you could enjoy HF access via the multibander in your parked car while taking in a baseball game. Conventionally two extra transceivers are required for KSS operation a Commander and a Transporter but the TS-2000/2000X/B2000 has Transporter functions built in. This means you can operate it remotely with a single mobile or handheld unit, such as the TH-D7A or TM-D700A, transmitting 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 (with LCD confirmation), switch memory channels, and much more all remotely. Kenwood Skycommand System II Plus is the most sophisticated version yet developed, enabling full-duplex operation with access to such HF functions as RIT/XIT, mode switching (USB, FM, etc.), splitfrequency operations on/off, and memory shift. Control is effected via simple TNC, compatible with the AX.25 protocol. In addition, if a second TS-2000/2000X/ B2000 unit is used as the Commander, you have control over noise reduction, noise blanker on/off and antenna switching among other functions.

Introduction

This document summarizes the extensive battery of tests performed by the ARRL Laboratory for each unit that is featured in QST "Product Review." For all tests, there is a discussion of the test and test method used in ARRL Laboratory testing. For most tests, critical conditions are listed to enable other engineers to duplicate our methods. For some of the tests, a block diagram of the test setup is included. The ARRL Laboratory has a document, the ARRL Laboratory Test Procedures Manual, that explains our specific test methods in detail. This manual includes test descriptions similar to the ones in this report, block diagrams showing the specific equipment currently in use for each test, along with all equipment settings and specific step by step procedures used in the ARRL Laboratory. While this is not available as a regular ARRL publication, the ARRL Technical Department Secretary can supply a copy at a cost of $20.00 for ARRL Members, $25.00 for non-Members, postpaid. Most of the tests used in ARRL product testing are derived from recognized standards and test methods. Other tests have been developed by the ARRL Lab. The ARRL Laboratory test equipment is calibrated annually, with traceability to National Institute of Standards and Technology (NIST). Most of the equipment is calibrated by a contracted calibration laboratory. Other equipment, especially the custom test fixtures, is calibrated by the ARRL Laboratory Engineers, using calibrated equipment and standard techniques. The units being tested are operated as specified by the equipment manufacturer. The ARRL screen room has an ac supply that is regulated to 117 or 234 volts. If possible, the equipment under test is operated from the ac supply. Mobile and portable equipment is operated at the voltage specified by the manufacturer, at 13.8 volts if not specified, or from a fully charged internal battery. Equipment that can be operated from 13.8 volts (nominal) is also tested for function, output power and frequency accuracy at the minimum specified voltage, or 11.5 volts if not specified. Units are tested at room temperature and humidity as determined by the ARRL HVAC system. Also, units that are capable of mobile or portable operation are tested at their rated temperature range, or at 10 to +60 degrees Celsius in a commercial temperature chamber. ARRL Product Review testing typically represents a sample of only one unit (although we sometimes obtain an extra unit or two for comparison purposes). This is not necessarily representative of all units of the same model number. It is not uncommon that some parameters will vary significantly from unit to unit. The ARRL Laboratory and Product Review editor work with manufacturers to resolve any deviation from specifications or other problems encountered in the review process. These problems are documented in the Product Review. Units used in Product Review testing are purchased off the shelf from major distributors. We take all necessary steps to ensure that we do not use units that have been specially selected by the manufacturer. When the review is complete, the unit is offered for sale in an open mail bid, announced regularly in QST.

Transmitter Output Power

Test description: One of the first things an amateur wants to know about a transmitter or transceiver is its RF output power. The ARRL Lab measures the CW output power for every band on which a transmitter can operate. The unit is tested across the entire amateur band and the worst-case number for each band is reported. The equipment is also tested on one or more bands for any other mode of operation for which the transmitter is capable. Typically, the most popular band of operation for each mode is selected. Thus, on an HF transmitter, the SSB tests are done on 75 meters for lower sideband, 20 meters for upper sideband, and AM tests are done on 75 meters, FM tests are done on 10 meters, etc. This test also compares the accuracy of the unit's internal output-power metering against the ARRL Laboratory's calibrated test equipment. The purpose of the Transmitter Output-Power Test is to measure the dc current consumption at the manufacturer's specified dc-supply voltage, if applicable, and the RF output power of the unit under test across each band in each of its available modes. A two-tone audio input, at a level within the manufacturer's microphone-input specifications, is used for the SSB mode. No modulation is used in the AM and FM modes. Many transmitters are de-rated from maximum output power on full-carrier AM and FM modes. In most cases, a 100-watt CW/SSB transmitter may be rated at 25 watts carrier power on AM. The radio may actually deliver 100 watts PEP in AM or FM but is not specified to deliver that power level for any period of time. In these cases, the published test-result table will list the AM or FM power as being "as specified." In almost all cases, the linearity of a transmitter decreases as output power increases. A transmitter rated at 100 watts PEP on single sideband may actually be able to deliver more power, but as the power is increased beyond the rated RF output power, adjacent channel splatter (IMD) usually increases dramatically. If the ARRL Lab determines that a transmitter is capable of delivering its rated PEP SSB output, the test-result table lists the power as being "as specified." Key Test Conditions: Termination: 50 ohms resistive, or as specified by the manufacturer. Block Diagram:

CW Keying Waveform Test

Test Description: The purpose of the CW Keying Waveform Test is to determine the device under test's RF output envelope in the CW mode. If the transmitter under test has several CW modes, these measurements are made at rated output power for each mode. A picture of the oscilloscope screen is taken of the results under typical operating conditions and in any other test conditions that result in a waveshape that is significantly different from the others (more than 10% difference, spikes, etc.). The first and second dits are shown in all modes. If the risetime or falltime become too short, the transmitter will generate key clicks. Most click-free transmitters have a rise and fall time between 1 ms and 5 ms. The absolute value of the on delay and off delay are not critical, but it is important that they be approximately the same so that CW weighting will not be affected. Some transmitters used in the VOX mode exhibit a first dit that is shorter than subsequent dits. Other transmitters can show significant shortening of all dits when used in the QSK mode. The latter will cause keying to sound choppy. The first dit foreshortening is expressed as a "weighting" number. In perfect keying, the weighting is 50%, meaning that the carrier is ON for 50% of the time. Key Test Conditions: The transmitter is operated at room temperature at rated output power into a 50-ohm resistive load. The power supply voltage is nominal. Attenuators are adjusted to obtain 3 volts RMS to the oscilloscope. Test Result Summary: Captions (Figures on next pages): All Figures are 10 ms/division., unless otherwise noted. Figure 1. This shows the first and second dits in Full QSK mode.

Transmit Keyer Speed

Test Description: This test measures the speed of the internal keyer on transmitters so equipped. The keyer is tests at minimum, midrange and maximum speeds and the time from dit to dit is measured using an oscilloscope and used to calculate the speed using the "Paris" method of code speed calculation.

Transmit Composite Noise

Test Description: The purpose of the Composite-Noise Test is to observe and measure the phase and amplitude noise, as well as any spurious signals generated by the device under test transmitter. Since phase noise is the primary noise component in any well-designed transmitter, it can be assumed, therefore, that almost all the noise observed during this test is phase noise. This measurement is accomplished by converting the output of the transmitter down to a frequency about 10 or 20 Hz above baseband. A mixer and a signal generator used as a local oscillator are used to perform this conversion. Filters remove the dc component as well as the unwanted heterodyne components. The remaining noise and spurious signals are then observed on the spectrum analyzer. The lower the noise as seen on the plot, the better the transmitter. Key Test Conditions: Transmitter operated at rated output power into a 50-ohm resistive load. Transmitter operated at room temperature. Frequencies from 2 to 22 kHz from the carrier are measured. Ten sweeps are averaged on the spectrum analyzer to reduce noise. Block Diagram:

Receive Frequency Range

Test Description: This test measures the tuning range of the receiver. The range expressed is the range over which the receiver can be tuned. Most receivers exhibit some degradation of sensitivity near the limits of their tuning range. In cases where this degradation renders the receiver unusable, we report both the actual and useful tuning range. Test Results: Minimum Frequency

FM SINAD and Quieting

Test Description: The purpose of the FM SINAD and Quieting Test is to determine the following at a test frequency of 29 MHz and additional test frequencies on any VHF and UHF bands: 1) The 12 dB SINAD value. SINAD is an acronym for "SIgnal plus Noise And Distortion" and is a measure of signal quality. The exact expression for SINAD is the following: SINAD = Signal + Noise + Distortion Noise + Distortion (expressed in dB)

If we consider distortion to be merely another form of noise, (distortion, like noise, is something unwanted added to the signal), we can further reduce the equation for SINAD to: SINAD = Signal + Noise Noise (expressed in dB)
If we now consider a practical circuit in which the signal is much greater than the noise, the value of the SIGNAL + NOISE can be approximated by the level of the SIGNAL alone. The SINAD equation then becomes the signal to noise ratio. The approximation now becomes: SINAD = Signal Noise (expressed in dB)
For the 25% level of distortion used in this test, the SINAD value can be calculated as follows: 1 SINAD = 20 log (1/25%) = 20 log 4 = 12 dB 2) The level of unmodulated input signal that produces 10 dB of quieting if specified by the manufacturer. 3) The level of unmodulated input signal that produces 20 dB of quieting if specified by the manufacturer. The more negative the number, expressed in dBm, or the smaller the number, expressed as voltage, the better the sensitivity. Test Results:

Blocking Dynamic Range

Test Description: Dynamic range is a measurement of a receiver's ability to function well on one frequency in the presence of one or more unwanted signals on other frequency. It is essentially a measurement of the difference between a receiver's noise floor and the loudest off-channel signal that can be accommodated without measurable degradation of the receiver's response to a relatively weak signal to which it is tuned. This difference is usually expressed in dB. Thus, a receiver with a dynamic range of 100 dB would be able to tolerate an off-channel signal 100 dB stronger than the receiver's noise floor. In the case of blocking dynamic range, the degradation criterion is receiver desense. Blocking dynamic range (BDR) is the difference, in dB, between the noise floor and a off-channel signal that causes 1 dB of gain compression in the receiver. It indicates the signal level, above the noise floor, that begins to cause desensitization. BDR is calculated by subtracting the noise floor from the level of undesired signal that produces a 1-dB decrease in a weak desired signal. It is expressed in dB. The greater the dynamic range, expressed in dB, the better the receiver performance. It is usual for the dynamic range to vary with frequency spacing. Key Test Conditions: AGC is normally turned off; the receiver is operated in its linear region. Desired signal set to 10 dB below the 1-dB compression point, or 20 dB above the noise floor in receivers whose AGC cannot be disabled. The receiver bandwidth is set as close as possible to 500 Hz.

Two-Tone 3rd-Order Dynamic Range
Test Description: Intermodulation distortion dynamic range (IMD DR) measures the impact of two-tone IMD on a receiver. IMD is the production of spurious responses resulting from the mixing of desired and undesired signals in a receiver. IMD occurs in any receiver when signals of sufficient magnitude are present. IMD DR is the difference, in dB, between the noise floor and the strength of two equal off-channel signals that produce a third-order product equal to the noise floor. In the case of two-tone, third-order dynamic range, the degradation criterion is a receiver spurious response. If the receiver generates a third-order response equal to the receiver's noise floor to two off-channel signals, the difference between the noise floor and the level of one of the off-channel signals is the blocking dynamic range. This test determines the range of signals that can be tolerated by the device under test while producing essentially no undesired spurious responses. To perform the 3rd Order test, two signals of equal amplitude and spaced 20 kHz apart, are injected into the input of the receiver. If we call these frequencies f1 and f2, the third-order products will appear at frequencies of (2f1-f2) and (2f2-f1). The greater the dynamic range, expressed in dB, or the higher the intercept point, the better the performance.

Key Test Conditions: Sufficient attenuation and isolation must exist between the two signal generators. The two-port coupler must be terminated in a 20-dB return loss load. The receiver is set as close as possible to 500 Hz bandwidth. Block Diagram:

Swept Dynamic Range Graphs
The following page shows one of the highlights of ARRL test result reports -- swept graphs on receiver two-tone, third-order IMD dynamic range and blocking dynamic range. These graphs are taken using National Instruments LabWindows CVI automated test software, with a custom program written by the ARRL Laboratory. Dynamic range measures the difference between a receiver's noise floor and the receiver's degradation in the presence of strong signals. In some cases, the receiver's noise performance causes receiver degradation before blocking or a spurious response is seen. In either case, if the noise floor is degraded by 1 dB due to the presence of receiver noise during the test, the dynamic range is said to be noise limited by the level of signal that caused the receiver noise response. A noise-limited condition is indicated in the QST "Product Review" test-result tables. The Laboratory is working on software changes that will show on the test-result graphs which specific frequencies were noise limited. These will be incorporated into future test-result reports. Being "noise limited" is not necessarily a bad thing. A receiver noise limited at a high level is better than a receiver whose dynamic range is lower than the noise-limited level. In essence, a receiver that is noise limited has a dynamic range that is better than its local-oscillator noise. Most of the best receivers are noise limited at rather high levels. The ARRL Laboratory has traditionally used off-channel signals spaced 20 kHz from the desired signal. This does allow easy comparisons between different receivers. There is nothing magical about the 20-kHz spacing, however. In nearly all receivers, the dynamic range varies with signal spacing, due to the specific design of the receiver. Most receivers have filter combinations that do some coarse filtering at RF and in the first IF, with additional filtering taking place in later IF or AF stages. As the signals get "inside" different filters in the receiver, the dynamic range decreases as the attenuation of the filter is no longer applied to the signal. Interestingly, the different filter shapes can sometimes be seen in the graphs of dynamic range of different receivers. In the case of the ARRL graphs, one can often see that the 20-kHz spacing falls on the slope of the curve. Many manufacturers specify dynamic range at 50 or 100 kHz. The computer is not as skilled (yet) at interpreting noisy readings as a good test engineer, so in some cases there are a few dB of difference between the computer-generated data and those in the "Product Review" tables. Our test engineer takes those number manually, carefully measuring levels and interpreting noise and other phenomena that can effect the test data. (We are still taking the two-tone IMD data manually.) The graphs that follow show swept blocking and two-tone dynamic range. In the blocking test, the receiver is tuned to a signal on 14.020 MHz, the center of the graph. The X axis is the frequency (MHz) of the undesired, off-channel signal. In the two-tone test, the receiver is tuned to a signal on 14.020 MHz, the center of the graph. The X axis is the frequency of the closer of the two tones that are creating intermodulation.

FM Adjacent Channel Selectivity
Test Description: The purpose of the FM Adjacent Channel Selectivity Test is to measure the ability of the device under test
receiver to reject interference from individual undesired signals while receiving various levels of desired signal. The desired carrier signal will be at 29.000 MHz, modulated at 1000 Hz, and the offending signal will be located at adjacent nearby frequencies with 400 Hz modulation. (NOTE: The SINAD Test in 5.3 must be performed before this test can be completed.) The greater the number in dB, the better the rejection.

FM Two-Tone 3rd-Order Dynamic Range
Test Description: The purpose of the FM Two-Tone 3rd Order Dynamic Range Test is to determine the range of signals that can be tolerated by the device under testing the FM mode while producing no spurious responses greater than the 12-dB SINAD level. To perform this test, two signals, f1 and f2, of equal amplitude and spaced 20 kHz apart, are injected into the input of the receiver. The signal located 40 kHz from the distortion product being measured is modulated at 1,000 Hz with a deviation of 3 kHz. The receiver is tuned to the Third Order IMD frequencies as determined by (2f1-f2) and (2f2-f1). The input signals are then raised simultaneously by equal amounts until 25 % distortion, or the 12 dB SINAD point, is obtained. Frequencies 10 MHz outside the amateur band are used to test the wide-band dynamic range. The greater the dynamic range, the better the receiver performance.

Notes 1, 2
Notes: 1. FM Narrow for all tests in this table. 2. Test is noise limited. In FM, this results in a reading that is somewhat inaccurate. The actual dynamic range is probably a few dB worse than the figures indicated. While this may sound opposite of what is expected, the presence of noise means that a stronger signal is required to have a product equal to the measured SINAD and the result is a number that appears better than it would be if there were no noise.

IF Rejection

Test Description: This test measures the amount of first IF rejection for superheterodyne receivers by determining the level of signal input to the receiver at the first IF that will produce an audio output equal to the MDS level. The test is conducted with the receiver in the CW mode using the 500 Hz, or closest available, IF filters. Any audio filtering is disabled and AGC is turned OFF, if possible. The test is performed with the receiver tuned to 14.020 MHz for receivers that have 20-meter capability, or to a frequency 20 kHz up from the lower band edge for single-band receivers. The greater the number in dB, the better the IF rejection. Test Results: Frequency

Test Description: This test measures the audio power delivered by the receiver. The manufacturer's specification for load and distortion are used. For units not specified, an 8-ohm load and 10% harmonic distortion are used. Test Results: Specified Distortion 10% T.H.D.
Specified Load Impedance 8 ohms
Audio Output Power 2.31 W
IF + Audio Frequency Response Test
Test Description: The purpose of the IF + Audio Frequency Response Test is to measure the audio frequencies at which the receiver audio drops 6 dB from the peak signal response. The frequency-response bandwidth is then calculated by taking the difference between the lower and upper frequency. Test Results: IF Filter Use/Unit Mode CW CW USB LSB AM
Nominal Bandwidth Hz 500 WIDE WIDE WIDE NARROW
Low Freq (Hz) 551 Hz 288 Hz 445 Hz 471 Hz 146 Hz
High Freq (Hz) 1042 Hz 1717 Hz 2356 Hz 2269 Hz 2476 Hz
Difference (bandwidth) 491 Hz 1429 Hz 1911 Hz 1798 Hz 2330 Hz

Squelch Sensitivity Test

Test Description: The purpose of the Squelch Sensitivity Test is to determine the level of the input signal required to break squelch at the threshold and at the point of maximum squelch. This number is not usually critical. A result anywhere between 0.05 and 0.5 V is usually useful. The maximum can range to infinity. Test Results: Frequency 29.0 MHz 52.0 MHz 146 MHz 440 MHz 14.2 MHz

S-Meter Sensitivity

Test Description: The purpose of the S-Meter Test is to determine the level of RF input signal required to produce an S9 and S9+20 dB indication on the receiver S meter. This test is performed with the receiver in the CW mode at a frequency of 14.200 MHz. The nominal IF filter bandwidth is 500-Hz. A traditional S9 signal is a level of 50 uV (an old Collins receiver standard). The Collins standard S unit was 6 dB. This is not a hard and fast rule however, especially for LED or bar-graph type S meters. Test Results: Frequency Preamplifier V Notes 1.02 MHz OFF 1.07 mV 1 1.02 MHz ON V 14.2 MHz OFF 110.0 14.2 MHz ON 24.MHz OFF 170.MHz ON 14.MHz OFF 58.MHz ON 5.MHz OFF 62.MHz ON 4.84 Notes: 1. Amateur transceivers often have a high-pass filter with a cut-off below 1.8 MHz to reduce interference from nearby AM broadcast stations. Poor S-meter sensitivity on 1.02 MHz is an indication of this.

Notch Filter Depth and Attack Time
Test Description: This test measures the notch filter depth at 1 kHz audio and the time required for auto-notch DSP filters to detect and notch a signal. Test Results: Frequency

Notch Depth

14.2 MHz 14.2 MHz 14.2 MHz

>40 dB 30 dB 70 dB

Notch Type (note 2) Auto, 1 tone Auto, 2 tones Manual, Beat Cancel
Attack Time 25 ms N/A N/A
Notes: 1. On receivers where the AGC is controlled by the DSP filtering (such is the case with the TS-2000), notching out a strong carrier can produce a change in AGC voltage, with a resulting change in level of all other received signals. On the TS-2000, the audio output level changed 30 dB when the notch was engaged. To get an accurate measurement of notch depth, AGC is turned off on such systems (if possible). With the AGC off, a notch depth of over 40 dB was measured on the TS-2000. 2. The TS-2000 has several kinds of notch options. There is a multi-tone, automatic DSP-based notch, an automatic beat cancel function, and a manual beat cancel function.

BIT-Error-Rate Test (BER)
Test Description: This test measures the data throughput rate for 9600-baud packet communications. Slower baud rates such as 1200 baud are not significantly effected by the transceiver's audio circuitry, which is why the microphone jack and speaker jacks can be used for TNC connections at slower speeds. At 9600 baud and above, the circuitry used to filter voice signals must be bypassed in order to get a clean signal through. The transceiver can still introduce noise and distortion to signals between these points however. 9600-baud communications is generally considered to be a "strong signal" mode. Therefore, if the BER is poor near the 12-dB SINAD level, this should not be seen as a reason to exclude a particular transceiver from consideration. However, if a transceiver performs well at low levels as well as high levels, it will give decent performance over a wide range of band conditions. A BER of less than 1.0x10-5 is exceptional. A level near 1.0x10-4 is quite good and a level of 1.0x10-3 is all but unusable. For more information on BER, see "9600-baud Ready Radios: Ready or Not?" in May 1995 QST.
