What you see is a variable talkback module for
export radios.
First off, we install them in our radios if you want us too! We even
warranty any of our work for life, but that goes for all work we do!
Ever have a Galaxy radio that in order for your talkback to work
your echo board has to be on. But the problem is you squeal like a
pig! Why? Because you can't shut off your talkback without turning
the echo off. The only thing you can do is either lower your mic
gain which stinks because now people can't hear you as good, or shut
off your echo, and that's the reason you bought the radio in the
first place! Variable talkback allows your talkback to stay on, but
you lower its volume so you don't squeal! Why cb shops offer this is
stupid, and 9 times out of 10 when they do offer it the monkey tech
installs it wrong! Do yourself a favor and if you want variable
talkback call us!
