[Drake] TR7 PA problem

[ik2bcp - Guido Tedeschi]

I want to thank very much all the people that answered very quickly to my
message.
Unfortunately, the PIN diodes are all ok, I checked now all the diodes just
to be sure, but I was already almost sure of this because yesterday I
measured the CW RF output from the predriver, which is after the diodes and
the high-pass filters, and it was almost the same for all the bands with the
same Carrier setting.
It seems to be the PA (driver or finals) that losts his broadband (almost
constant) amplification, now I have to remove the PA and check it carefully.
I will let you know if I will find the problem.
Thanks to everybody
73 and ciao
Guido, ik2bcp
