[Yaesu] MK-V receiver issue after electrical storm

[Dave Maley]

Bill;

I had a similar issue, but with a 1000D.  Tha radio uses a pin diode to
switch in the transmitter and a small relay to isolate the receiver.  I
found the pin diode shorted.  Everything worked, but like you said, the
receiver lost performance. The crazy thing is, I used a 1N4007 diode to
replace it, and it worked fine.
