I promise I will double check it.... but it will take a day or two!!!!!!!!
I am "promised to the Missus" for some tasks here at home..... and THIS is how i stay married for 52 years!!!!!!!!!! :)
I promise I'll check!!!
Don;'t know the board number and the SAMS doesn't show it....
I'll have to crack it back open and take a look......
Well... for one... there is not a single mic audio amplification stage before the audio chip. Literally.... passive components.... no gain....... anywhere in the path on the...
The actual "first" problem I found is covered in the MicCircuit image below.
RCV was great to the ears to begin with.
XMT carrier was great on the scope and spectrum analyzer.
But modulation was "non existent". Seriously.... I would say no more than 5%.
R58 (33K) and R59(5.6K) were swapped...
Okay... I only woke this one up to let you all know the final answer. The final act occurred today (Sat, April 4).

If I can find a way to get it to you... I have about a 380-ish Mb ZIP file of everything I have on the Console V (and Sidebander 5 too). Factory service manual, operator's manual, a number of schematic images.....
I tried to upload it here but it blew out .... saying the file was too big.

To make things more clear, I am posting two pics more!!!! The area of concern is on a page split... so I have screen shot each area to try to get the most of what is involved here.
Part One shows the microphone and the mic jack with the wiring trailing off to the right.
Part Two Shows the...
Dan, most likely I haven't done a good job in describing what I meant. I'm going to try to write in support of the pic I uploaded:
If you will, look right in the middle of CKT TRACES 19, 80 and 81.... where R57, R59 and C83 meet together. That is the "tie point" I was trying to describe...
