Really not sure what this thing is. I got such a good deal yesterday on 2 generations worth of CB equipment from a widow on craigslist for $75. Bunch of pre amps, antenna switches, ext speakers, 3 portable SSB units and 5 base stations. I also got this small enclosure that doesn't have anything to plug a cable into and just has an on off switch and a pot with +/- symbols on the front. It had a 9v battery clip inside. Does anyone know what this thing does?
