Looking at the manual, there is a relay in the circuit near the antenna connector, looks like that is the T/R relay. There is a bunch of relays on the output filter board. Lots of places for Deoxit! Good luck with it.    Mike Cumbo, ND4S

Hi Folks

I am going to be acquiring the above T/RX, in a non working condition, 
well not 100%, low RX and no TX.

Is there any other faults that are known about that i should be aware 

No manual at the moment, i think seller states one with it.

Is there a relay involved with T/RX changeover?

As always any and all advice/help much appreciated

This is my 2nd request as the 1st one didn't seem to go anywhere, please 
ignore if 1st one surfaces.
