Less than 1/2 the size of an SD card this pre-amp allows use of
dynamic and electrect microphones with transceivers that require
carbon or other non-dynamic type microphones. Has adjustable trim pot.
Installation instructions included. Used for 2 1/2 months last season
while a temporary Micro-Air radio was in my ship until I could
purchase and install a new Becker.

shipping in the US. Pictures on request.
