Joel, I took a lightning hit with my 847 in 1997. It was a big one, took
out my sat tv, phone, TNC's , KCT card, computer's, etc. I had
disconnected the antennas, power, everything except the modem(remember
them?), that's where it got in, through the phone line, to the rs-232 port.
I had an APRS station I left up and didn't disconnect during the event and
it was fine! Go figure. To make a long story short I sent the 847 in that
was only 3 weeks old to be looked at. Yaesu graciously fixed it under
warranty. I was also Leary about keeping a lightning compromised radio after
a lightning hit but I really didn't want to sell it to anyone so I kept it.
Now 11 years later it is still working the birds! So you never know, good
luck if you decide to go for the repair.

Subject: [amsat-bb] FT847 and Lightning
I appreciate everyone who has responded to my incessant questions here
lately regarding radios, etc.. Tuesday morning, I took a hit to my
VHF/UHF vertical antenna. It came into the ham shack and got the
either the LVB Tracker, the G5400 controller or both (the G5400
controller is sluggish and the LVB tracker doesn't even turn on)
my PC's NIC
my kids' PC's NIC
and reset a couple of GFI outlets throughout the house.
I have been asking the questions of the radios because I have an FT857
that I was not in use at the time; however, it does not have full duplex
capability. I really like the 857 and wouldn't mind having another, but
the FT817 would be (from what I read) a great little receiver and it's a
bit less expensive (I can add filters to it at that cost). As for the
847, I work in telecom and I know what kind of damage you fight from a
lightning strike. I could send it to Yaesu, but when it comes back,
I'll be fighting with it from now on. I just don't want to spend $500
for repairs only to have to send it back six months later for repairs
again. I'll try to fix it, but that's going to be kind of slow - it'll
also make for a good teacher.
As for the rotor controller, I was already going to completely take down
the HEO antenna array and put up either homebrew eggbeaters or
turnstiles. The 22 elements on 2m and 44 elements on 70cm are a tad
overkill for what is up there and they need work. I really want to put
a hexbeam up on that tower anyway. :)
I guess I'm looking for advice. Do I send the radio to Yaesu for repair
or purchase a companion for the 857? Any other advice is also welcome.
Folks, unplug and disconnect everything. We had another lightning storm
last night. At 3am, my wife woke me and said, "Honey, there's
light..." I ran into the hamshack and just pulled everything out of the
wall. It's funny looking back on it, but I still have a sick feeling in
