Trent,
I looked it up and I think it's a DX Engineering speech processor. They
made 2 units, one for Collins 32-Sx transmitters, and one for the KWM-2
transceivers. Here are the model numbers:

LC-1-32S (for transmiiters)
RF LC-2-TR (for transceivers)

I believe the "RF" model is a true RF speech processor, while the other one
is just an audio compressor.
Hope this helps....

Anyone know who made this speech compressor and maybe even what type
batteries it uses?

Thanks in advance,
