If you can find the circuit for the compression amp of a GRT21 this circuit
works great. Makes your radio sound like a used car commercial. If set up
right it can keep average sideband power up and prevent overmodulation. No
ICs and a fairly small total parts count.. IF you can find the schematic for
the GRT21 you have to be careful, there were two audio input boards. The
compressor board and a straight audio board. The transmitter used one or the
other, not both.

Nonsense... if the original ALC/modulation limiting is in tact within
the radio... this speech processor will not over modulate. However, it
will certainly boost your average power on AM and SSB!

Then why does your processor include amplitude limiting if it isn't
needed? And why does your 2-transistor amp have the gain of only one
transistor?

I await your test data. So how do you intend to make your
measurements?

If the limiter is in tact within the radio... the redunantcy of the
speech processor limiting can be shut off. However, if the radio has no
limiter... the the speech processor must be adjusted to do the limiting
function. So it'll work either way.

What happened to the rest of the post, Brain? Why use two transistors
when you can get the same gain with one? What about your published
non-linear data for your linear amp? What equipment did you use to
make your measurements for real power and harmonic distortion? And
where's that schematic?

And you whine about -me- drifting off-topic.... sheesh!!!

I'll bet 95% of the cbs operating today have the ALC/Modulating limits
circuits defeated. Heck back in the 70's that was the first thing
hackjob socalled techs would to a radio.
