[1000mp] Important question

[Steve Fraasch]

Yuri:

In the spring, I left my MK V connected to my high dipole as a nasty snow squall came thru.  The precipitation static was very strong.  I was at a ballgame practice during the storm and was unable to disconnect.  When I returned, I entered the shack and noted that the receiver was dead.  I had determined that Q6451 (2SD667D) on the tuner main unit had blown open.  When I ordered a replacement from Mouser, this part was available in both a low and high VCE max version.  I immediately wondered if Yaesu had installed the lower voltage version.  I replaced it with the higher Vce max part, and since then no problems.  I am careful though to disconnect the antenna when a storm comes thru.  I am not sure this is your problem, but I thought I'd mention it.

73,

Steve, K0SF

I have 80 and 160 m antennas very close to each other (within 20 feet
probably) and I use BPF's on each radio. Still blew the front end on one of
the MPs Mark V (80 m ) while operating the other one barefoot on 160... I
just wonder if adding stubs would help?
Thanks.
