All it takes is one third harmonic to ruin your whole day.

Thank you all!!
That was exactly it, the LM-1877!
Actually, now that you mention it, I recall seeing it in my Forest Mimms books
from Radio Shack years ago.
And Mike, thanks for confirming the details of the circuit operation for me.
Thanks again!

It kinda sounds like I may be one of the few people that is a VE on here (at
least that reads regularly).
The last time I checked, the Technician test is about 35 questions out of a
pool of around 350 questions. The General test is also 35 with around 400
questions in the pool, and the Extra
Some time back I sold a few of the Spectrum 900mhz paging transmitters, and at
the time I couldn't find the manual so I sold them without the manual. Guess
what? I found the manuals! At that time several asked me if I had the manuals,
now I have them scanned in PDF format. Manuals are complete.

Good luck, these are long files, not too bad if you have a fast connection.

Taking a bit of a guess, since the board appears to be some sort of
encoder or decoder for audio,I would suspect that it could be used as
a single tone burst encoder or decoder. The CG module position would
have provisions for PTT and audio out as well as disc. audio in and
squelch
Thanks, that was it.
And you know what. Now that I see it, I do recall reading about that power
op-amp in one of my Forest Mimms books years ago.
Also it is interesting in that they used a 2W driver in a bridged configuration
to drive a transistor amp. I guess higher power op-amps were not
