Yes..it is a noise filter...remove it and jump pin 2(input) to pin 4(output) with a piece of wire...had several of these go bad...that nf board didn't do much for noise anyway

Rick...I've searched the web night and day for radio repair info. I'm convinced that you are the Mac Daddy Radio GURU....thanx a million times over for the help that you've givin me and other wanna be radio doctors around the world.

Anybody know of any mods for this unit besides the frequency conversion?

If Rick can't help you resolve the problem...chances are it can't be fixed.He is the best!

Many Many thanks Rick....your a genius!!!! Aligning radio now....was a free radio and thought it was worth taking a look at.Thanks again

Doug

NF board is there

Has audio at pin 2....no audio at pin 4

Touched up some solder joints....looks like the NF board has never been touched

Shorting pins 1 and 2 did the trick!!!!

Has very very weak audio at r231 and at pin 1 of J5....about the same as whats coming out of speaker. P.A. works

Thanks again Rick for your time....no audio present at pin 4.
audio IC voltages:
pin 1 13.2
2 6.4
3 0
4 0
5 1.2
6 1.2
7 0
8 0
9 6.6
10 12.5

Yes the squelch works also

yes...audio is clear

Yes the P.A. works. Volume control works but has very low audio. Has 8V at mic board. Almost as though the input to the audio ic is weak. Help!! Thanks again

Replaced the 5 caps...still no good

Sorry...should have said sounds like it's slightly distorted and very low in audio

Thanks Redeye for the response...Had 8 volts at mic board, Changed audio IC again,now it has rx audio but severely choked back.Any other tips? Thanks again

No rx audio, has rx signal,new audio ic. Heard this radio has had audio issues. Tx audio good,roger beep good. Any ideas...thanks
