Previous tampering by an owner can bring you down. You have to fix what they did before you can fix the original problem. Good video, thank you.

Oh Peter, I envision a "tech" with his rusty soldering iron with corroded tip -of course-, fumbling inside the nice radios. What a nightmare. Ok, I am awake now 😊 Thanks for your videos

As always, another great video. And once again, the golden screwdriver strikes and leaves his mark. It looks like an amateur (not ham) tried to fix the radio and didn't put all the parts back where they go. So that fixed the radio? Unbelievable. 73 from W Rusty Lane K9POW in eastern Tennessee

I thought for sure this fault would have been related to an overloaded front end: static discharge, transmitting into the reciever, etc. This was a fault located between the ears.

First i thought that the fault is at the TX/RX switching diodes, faulty diodes may generate noise. But the real fault.... i have no words for it. When unscrewing and unmounting any equipment it is ALWAYS recommended to collect all screws, washers etc. in a small box to check at the end of the work, if anything has been left.

I've used this radio as a packetradio transceiver for many many years. Daily a lot of activity on my Gateway from 2m (1k2 simplex) to a 70cm (9k6) Digipater next to me. But in time, the power module f..ckt up and has to replace several times. Afte some replacements, the loosen contacts are unable to solder. It was time for a new trx... Peter, it is a FT-212 RH (not RM) vy73 DF2EAN Frank

@@TRXLab As I wrote, the TRX ran continuously 24/7. After replacing the PA module, I've added a small fan to the heatsink. In addition, a 40°C temperature switch (normal open) from a washing machine (spare part). The fan would turn on above the temperature and turn off below. It worked very well for years, despite the high load from packetradio. If someone retrieved data from the 70cm 9k6 side (e.g. mailbox), it took some time on the 2m 1k2 side. So the FT-212rh was in use a lot. After a long time, the PA module broke again and was replaced with a similar 30w module. but that broke again. A short time later I moved and packet radio does not work at the new QTH.

MOST R.F POWER AMP MODULES ARE SEVERAL AMPS ON ONE CERAMIC DIE, USING DRIVE FROM THE RADIO TO SUPPLY THE SIGNAL TO GET THAT R.F UP TO THE 25 OR 40/45 WATT OUITPUT LEVEL.

THE MODULE REQUIRES A MAX. INPUT OF .6 WATTS, FOR FULL OUTPUT @ 13.8V.

WHY IS THE OUTPUT COUPLED TO THE GROUND OF THE R.F CONNECTOR? SOMEONE FIDDLED WITH A GOLDEN SCREWDRIVER!

PIN DIODE/S MIGHT BE DEFECTIVE.

TO ME, .25 uV IS A DEAF RECEIVER. SWEEP TUNE THE RX SECTION AND REPLACE THE RF AMP AND ADJUST THE STAGES, BUT FACTORY 'STANDARDS' ARE NOT THE GENERAL RULE. I ALWAYS TRY TO GET THE BEST SENSITIVITY THROUHOUT THE ENTIRE RANGE OF THE RECEIVER.

TOO MUCH SILICONE GREASE CAN INCREASE THERMAL PROBLEMS AND AFFECT OUTPUT. LOOKS LIKE THE PERSON GOOPED IT UP. THIN APPLICATION ONLY, THE MORE USED, IS DETRIMENTAL TO STABLE R.F OUTPUT.

POORLY TUNED RX SYSTEM.
