Question: If I have 7.2Vdc on U7 pin 1 on RX... is it possible that a
problem with relay K1 ??? Because on RX, relay K1 should be in
another position as I can figure it out on the schematic !?!?!?!?

Hi,
I verified all voltages in the troubleshooting section... both RX
and TX.
I have a few readings that are not as the manual.
In RX, U7 (RF power module) PIN 1, I have 7.3 and should be to
0 !!! All other pins are OK.
In TX, U5, the leg on the same side of C9 is 5V and the leg on the
side of C65 drop to 2.7V (should be around 4.7 ???)
All other measurements in the troubleshooting section are in the
spec range.
So, If I consider that my problem is in RX..... Is these results
could help ???

Hi to all,
Last week, my transverter XV50 was unable to receive properly...
Only a small voice in the background... no S unit... the guy
normally give me 10 or 20 over S9... After a new alignment
procedure, I was unable to peak R13 to the desired level. I was
unable to get more than 0.043 V. So my conclusion was that Q3 is
dead.
