Do you have a copy of the schematic diagram. If so I may be able to help, I have all the Galaxy schematic diagram but not this one.

It sounds like it is a fault on the EB-2000 echo board if so, just try this one disconnects J2 and J3 and connect them back to back (E.G. mic I/P to mic O/P and PTT I/P to PTT O/P) and give it a try, if it ok then the echo bridge IC is duff. If ok try TR40 could be O/S. Question is it the same on FM and AM?.
