[Amps] AL-1200 T/R problem

[Dave Hachadorian]

Sounds like oxidation of the normally-closed contacts of the T/R 
relay.  Remove or slice open the plastic cover and use one of 
these:

Subject: [Amps] AL-1200 T/R problem

My AL-1200 has developed a T/R switching issue. In about 5 out of 
10
transmissions the receive does not fully come back after 
releasing the PTT,
A click of the mike button or a dot on the paddle brings the 
receive back.

Any suggestions where to strat lookiong to clear this problem?

Thanks and 73,
Ken VA3KA
