I saw an auction for a Sampson Modulator which looks to be a way to
apply full plate modulated audio to the output section of a Collins
transmitter or transceiver. it has the "11 pin octal" socket which is
used, aside from relays, only two places I know of, the Collins S-Line
ham equipment and Hammond organ speaker cabs.

First, is that what this is?

Second, since the KWM-2 has no AM position, how is the BFO disabled
for AM rx operation? The audio would be unpleasant even if intelligible
if AM were listened to in a SSB mode.


My guess is that this was actually intended for illicit 11 meter use
but would be usable on any band.


11 pin Octal socket was used on a LOT of equipment in the 50/60s.

Your right tho....sounds like some sort of CB junk to me.

I used Collins S-lines and KWM2s for years. Never ever heard of a outboard
"AM Modulator". Why anyone would want to do that is beyond me.
