i used to have one too - and as i remember, these radios were a little lacking in the transmitted audio department - they were deliberately set a little low, easy fix, adjust the fm dev pot on the board a bit.
try and find one that someones modded for the old legals as well - these rigs had a terrific front end on recieve. well, it is a uniden!
good luck!
