This ceramic insulator have so shitty thermal conductivity, that lack of thermal compound make no difference. Mike

For AM it's simple. I would inject audio from external processor to point marked with red arrow and take out C262 Beware, that you must use at least external limiter to do not overdrive. I use for that purpose external mic preamp, 12 band EQ and compressor/limiter. Sounds insane. SSB is...

Bummer. No schematic - no help. Mike

What is board nr?

Is there any schematic of that radio? I could help.

Same bullsheet I had. Board v 1.6. I hope they improve that radio in next revisions, otherwise its crap. It have potential, but need some love from R&D department. Mike

Show me schematic. Mike

Not worth the time, money and effort. Mike

Sounds like CMC/RF issue to me. Check on dummy load and come back with result. Mike

Easy way to use socket which disconnect internal meter when the other is connected. I've done it many times in different radios. Mike

For 30+ years technology? Bollocks.

From my old database: Find jumper J2, you will notice that it is on pins P3 and P4 If you remove it you will have coverage from 26.000-29.700 MHz If you place it on pins P1 and P2 you will have coverage from 26.000-32.000 MHz Now reset the CPU by pressing the button below J2 To get a channel...

Be careful. Mic socket is connected directly to the processor. One mistake connecting other mic and cpu is fried. Later they added transistor buffer. Mike

Could you measure their capacitance and post the result? Thank you. Mike

If you just ground pin 10 radio will go up one band. No other mods needed.
