Hello TE:

Yeah I bought one of them a few years back. It did offer some gain and
punch in SSB and AM, but was most noticeable in SSB.

With other commercial speech processors available off E-Bay, you can
experiment around and compare.

I used to use a Diwa RF-440 Speech Processor, on a Motorola System 500
Mobile Radio with really good results. But had to modify the 440 to
supply the dc voltage to run the mic pre amp.

I also played around with a Cobra 148 GTL and a a few of the different
speech processors. What I found was the speech processor really did help
the unprocessed speech signal. But the gain of the processor had to be
turned down.

I had one radio with a outside antenna listening to the radio with a
speech processor transmitting into a dummy load. This way I could
compare the unprocessed to processed speech audio, in skip conditions
allowing me see what settings had a good punch. This also lets you know
how the thing will sound.

Its all a lot of fun to experiment around.

Jay, thanks for your insight...
