Worst than that.... I just connect my wideband NGen... I'm using my
rf probe too....
Now,
NGen OFF
Read at antenna jack 0.0 vrms
Ngen ON
Read at antenna jack = 0.5 vrms (ajusted my ngen to give me that result)
Read immediately at C28 on antenna jack side = 0.5 vrms also
====» Read at C28 on C1 side = 0.0 vrms !!
Am I on the good track ?!?!?!?
Further reading give me also 0 at C3 and C48

If someone could just give the actual Vdc of BOTH side of C3 (located
in RF section near U1) in RX state, it would be greatly
appreciated !!!
XV50 - No antenna (no signal) using Fluke DMM:
L2 side of C3 measures 4.2VDC; C48 side measures 0VDC
With N-gen at antenna using RF Probe:
N-Gen off:
L2 side of C3 measures ~1.0mv, C48 side measures ~1.0mv
N-gen on:
L2 side of C3 measures ~16mv C48 side measure ~16mv.
I measured the C48 side at both C3 and at C48 to see what drop there
might be across K2 relay contacts. There was minimal difference; less
than 0.1mv;
