I have no complete circuit and servicemanual for messure and no oszi.
my Know-how is also Not very high.?Tx, Display is fine.
At Power On the ?palim“ also not ?to hear. speaker and Headphonejack are checked.
What i hear was a quiet Power on ?palim“ on the cw Tone poti. I put a mic ampliphier on this?
btw. The cw-side tone ?is also not to hear in cw-tx mode.
could anybody help me what i can check and give me some meassuring points with voltage Ort so.
At the moment i have only a normal multimeter?
I warnt to give the sound back to this fine little transceiver.
my supposition is a failure in nf amp. like lm 386 dead or faulty voltage.
Thank ?you very much for Reading and any help or even ?a solution?
