[Elecraft] XV50 problem... I think I'm closer to the problem

[Jean-François Ménard]

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
