[Kenwood] Internal HF problem with TS850

[Markus]

Hi,

I already posted my problem before, that my speaker give during transmitting
distored audio back.
The reason is the +14V DC for the TDA2002 audio amp is HF "infected" (TX
frequency).
Wherever I will take the +14VDC for the audio amp, its always the same
problem.
If I supply the audio amp from an another external power supply, the problem
disappear.

I already changed:
- audio final amp
- the 2 caps near pin5 supply of the TDA2002
- the 2 caps (1000�F) at the X46 D/4 "Digital" board (=power board) near the
RF Choke coil L601


- the L601 seems that it went hot, because the tape around the copper wire
seems not new. maybe little overheated a time ago (I bought my TS850 at
second hand)

Somebody had a similar problem, and how did you solve it?
