I just got a uhf Mostar from a friend, it Xmitts and I am sure it receives but it has no audio, I seem to remember that the one at the race track had an external skpr on it but I don't remember where on the DB-15 on the back where the spkr leads go. I hope some one will remember this radio and let me know where the spkr lead goes.

The UHF 2 ch Mostar I have had about a foot of external speaker wires coming out the back under the power connector, but when I got the power connector replaced on it I had the shop remove the speaker wires, so now I'm not sure. I took the covers off thinking I could find where they unsoldered the wires but I couldn't. If anybody knows it would be Andy Brinkley.

The external speaker audio is on pins 8 and 15 on the Mostar
