Vic, when you consider the number of cycles the life span is on any type of
vacuum relay, that life span can easily be chewed up in relatively short order
if used for high speed QSK during several contests. However if used for high
voltage switching on occasional use, it could last a long time.

Subject: [Amps] Diagnosing relay problem
I have recently been suffering from intermittent attenuation of RX signals
through my amplifier, which has a vacuum relay (Jennings RJ1-A) in the output
and a HG d'Italia relay from max gain (see here: <a
href="https://www.mgs4u.com/RF-Microwave/RFrelays_misc.htm";
target="_blank">https://www.mgs4u.com/RF-Microwave/RFrelays_misc.htm</a>) in
the input. The problem is that I would like to determine which relay is
responsible before taking it apart!
I can't think of a way, and am considering replacing both of them. Does anyone
have an idea?
Also, has anyone experience with the HG d'Italia relays? I wonder if this was
such a good choice. It is fast enough, but I wonder about its lifespan.
