It sounds like your PLL is going out of lock............could be a faulty
trimmer capacitor that is used to warp the reference crystal on frequency.
Check the phase detector input for the reference frequency.

I have no clue how to service modern radios. I'll have to send it to
Yaesu.

I would concur -- I have an Icom 735, and at one time, after being on
for a few minutes it would go blank all across the spectrum -- the
inexpensive plastic trimmer caps for the VFO needed replacing; a
technician replaced them all with new ceramic caps, and that solved
the problem. Sounds like maybe Yaesu is using cheapo trimmer caps,
too. You might check their web site -- see if they have any service
sheets with common problems on your rig. You'll probably have to send
it in for service.

Unfortunately, I don't have the money to do so at this time. Somebody
reminded me that the last time I had it in for service, Yaesu kept it
for several months, and I had to keep calling them to get them to repair
it. The problem was a blown resistor-a resistor that was a common
problem on 8800's. I may not even fix it. Yaesu rigs don't seem to be
very high quality, at least not the HF receivers. I can get an older
Icom off Ebay for $3-400, and I may go that route. I searched for "Icom
receiver" and turned up 36 matches, of which only a couple were radio
mart offerings.
