I really enjoyed your "walk through the SAMS schematics as the applied to this patient. I got a TON of confirmation concerning the AM mod control. BASICALLY an audio shunt regulator using the modulation drive to "clamp down" on the mic audio as the modulation rises. A "closed loop" feedback system!
I too kind of wonder if THIS radio hadn't been scavenged to repair ANOTHER RADIO. I can't imagine why they would have pulled SO MANY parts out of that limiter..... when the transistor ALONE would have disabled it.
@dxradioshop I'm working on it,It's on the transmit board fixed a shit load of bad solder joints all ready,I'm pulling the transmit section out tonight.
Hi Stu!!!! I am watching.... but later in the early afternoon.

Glad I could help you learn something new my friend!
But as I say.... it was helpful to see you walk through it.
It is important to see how these radios work. It was fun walking through the steps etc.

No transmit mit 6241
Send it here and I will see what I can do for you

Yeah, there known for bad solder joints
