Hello To All:
I was operating in the ARRL DX SSB Contest this weekend.
Antenna is a roof mounted HF6V with good SWR's.
After about 100 successful contacts (barefoot) my PROII
began suddenly and quickly turning itself off during transmissions.
I thought perhaps RF was getting into the radio, but I have
operated this radio and antenna with an AL80A before and
never had this problem. After rig turning off, I turned off the power
supply (Astron SS-30M), turned it back on, and the radio would
boot back up again. (The PROI->III series takes about 10 seconds).
This happened about three more times. So I decided there
was a problem or intermittent in the power cord or PS. It checked out
OK on the DVM. Nevertheless, I didn't want to mess with it during
the contest, so I used another, almost new power cord and switched
to my backup PS, a Samlex SEC-1223. This worked fine for
a while then the problem happened yet again. This time however
the radio will not turn back on at all.
I have gone through the new power cord with the DVM and all
connections are solid and not corroded, fuses intact and in place.
I have tried the new power cord with the Astron too and the output
reads the proper voltage but the radio still won't turn on at all.
It may be my imagination, but when this problem first started
happening, when I turned on the PS power with the radio plugged
in, I THOUGHT
I heard a slight relay type "click" from the PROII.
I admit I could be wrong about this.
Is there some sort of relay in the power switch rail?So now the rig won't turn on at all no matter what I try.
Has this happened to you or anyone you knew?
And do you know what the problem turned out to be?
I am hoping and praying that it is something simple
and cheap like a resettable fuse that blew or maybe a
switch or diode.
I don't have the skills to hop on and troubleshoot this
rig, but something like a resetable fuse or diode I could check
and replace. I am very handy with a soldering iron, including
SMT.Or perhaps it's best just to bite the bullet and send it
to Icom Service in Bellevue and have them go all the way
$84 per hour service plus shipping and
insurance both ways.
Any and all thoughts and experiences appreciated.

PS: Finished the contest with my TS-940S/AT. Sweet
rig but boy did I miss the digital IF filters of the PROII.
