Hi all, i hope i have not sent this request for advice twice but here
goes (again).
I have the above radio, the fault is no rf out either in the 5 or 50
watt setting.
There appears to be no output on connector 39 on the exciter board, i
have checked all voltages on U1, and all the trannies, all appear to be
within spec, just a few millivolts out.
There is no increase in current rate when changing from RX to TX,
voltages appear to be ok on the finals board.
What is U2 , a quad uhf modulator barrier diode array, that is the only
item that i am unable to test, is there a suitable replacement?.
thanks in advance
