Flexible Circuit Board Repairing Keep the temperature of the soldering iron around 270 C during repairing. Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). Be careful not to apply force on the conductor when soldering or unsoldering. Notes on chip component replacement Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be damaged by heat.

SECTION 4 MECHANICAL ADJUSTMENTS
1. Clean the following parts with a denatured-alcohol-moistene swab: playback head pinch roller rubber belt capstan idlers 2. Demagnetize the playback head with a head demagnetizer. 3. Do not use a magnetized screwdriver for the adjustments. 4. After the adjustments, apply suitable locking compound to the parts adjusted. 5. The adjustments should be performed with the power supply voltage unless otherwise noted. Torque Measurement

TEST MODE This set have the test mode function. In the test mode, FM Auto Scan/Stop Level and MW Auto Scan/Stop Level adjustments can be performed easier than it in ordinary procedure. <Set the Test Mode> 1. Set the power select switch (S501) is A position. 2. Turn ON the regulated power supply. (All LEDs on the set lights up, and the clock is displayed.) Note: Press the [OFF] button, if the clock is not displayed. 3. Push the preset [4] button. 4. Push the preset [5] button. 5. Press the preset [1] button for more than two seconds. 6. Then the display indicates all lights, the test mode is set. <Release the Test mode> 1. Push the [OFF] button. 2. Return the power select switch (S501) to initially set position. See the adjustment location from on page 17 for the adjustment.

SWLing on the Road with Sonys XR-CA660X

By Ken Reitz KS4ZR

have to admit that Im a refugee from satellite radio. For years Ive had either Sirius or XM units in the car, but, as time passed and subscription fees climbed, I called it quits and sought an alternative. As a lifelong SWLer, I was disappointed in the lack of international broadcasters on either satellite service. Sure, XM carries the BBC World Service, and Sirius carries a truncated version as well as the wheel of rebroadcasts from World Radio Network. And, just recently, Sirius added CBC Radio One and CBC Premiere Plus, while XM added Canada 360 and Franc Parler. But, I was looking for more diversity, a wider range of broadcasters, some really esoteric music and an end to cables disease, constantly rising monthly rates. Thats why I turned to old fashioned shortwave radio in the car. Over the years Ive looked at mobile SWLing using portable shortwave radios, downconverters (tuning devices which convert your existing in-dash AM radio to tune the shortwave bands), even mounting my general coverage ham transceiver in the car. But, they all had drawbacks. I found that portable radios were cumbersome, not easily tuned, poor audio quality and susceptible to ignition and other electrical noise. The downconverters were easy to mount and hook up, but most were also susceptible to ignition noise and required a certain amount of mathematical gymnastics to determine the frequency. With the exception of the LFB Short Wave Converter* most were also poor performers. The ham transceiver was very sensitive but was bulky, not easily mounted (and a high risk of theft), suffered from poor audio but was less susceptible to ignition noise. The only thing left to do was to install a real in-dash AM/FM/SW radio.
ping. The Beckers price is high and SW coverage limited, so I checked out what Sony had to offer. In North America there is only one Sony dealer still selling in-dash AM/FM/SW radios: Durham Radio in Ontario, Canada. Worldwide, the only other Sony dealer selling these radios is an on-line retailer in the United Arab Emirates called Jackys. Jackys price is considerably cheaper, but the express shipping and customs duties make the final price more expensive than Durham Use small wire nuts to connect the new wiring harness to your Radio. stock speaker and power wires.
