Hi Andy, you certainly do not harass people, rather, I learn from you and you help folks. Your presence here is very valuable IMO.
Back to the beep: I replaced every electrolytic connected with the beep, checked most but not all the resistors (ohmmeter and visually), no luck, same applies to diodes, they work. Visually no burned resistor. And nobody was there to cut one (I saw this in a Tagra Pacific II once).
I did not check yet: the 2 green small value caps and TR33 for example.
And symptom did not change: there is a roger beep (releasing PTT triggers it, it has its duration), the only problem is that it is "silent".
The circuit gets 8V, since it works, well to my understanding of things.
Could not be the 2.2uF, as the beep has its "duration", but i replaced it, it was a grey one, so a pretty old one, maybe it'd have never failed but who knows.
What i would just like to understand, is what actually makes its "voice"?
The green caps give its frequency, could they be the culprit?
If the beep actually is there doesn't it mean that TR33 works?
After all it's just a beep, but it's nice to "brainstorm" on it, at least I learn something in the end
