Hi,

I have an FT-1000MP, the original, not Mk-V, not field, vintage is
1999. Recently I have noticed that if I turn the radio on 75 meters,
the receive is low.... until I just tap the mike or key, then the
signals jump up 10-20db, stay there for a while, and eventually, after
4-6 minutes, fade down, until another mike tap is applied. This will
continue all night. Antenna is a resonant dipole. It seems to happen
only on 75/80... preamp problem? should I switch to flat?
Suggestions?

Thanks!

Perhaps you're building up a static charge on the antenna in the dryer
winter weather? Then when you transmit it's being discharged? Not sure if
this would be workable with a transitter in line, but I used to put an NE-2
neon lamp across the antenna/ground connections outside (no series dropping
resistor). This would only let the static build up to about 70 volts before
discharging..

hhhmmm, could it be a dirty (or bad) relay? I have a Yaesu FT-102
(vintage around 1984 or so) It had trouble with one of the relays till it
were replaced.
It had the same symptoms as you describe.
Give Yaesu a call and ask for a tech.
Good luck.

Ya know, I spent good time EARLY this morning before work telling you what
the problem is and the fix and sent it to you directly. Too bad the
message bounced back.
Why is your e-mail address NO GOOD???

Sorry about the mail being bounced. I logged on to find that the
spammers filled the account up with junk. I emptied it out. Once
again, sorry, and I hope you didn't lose your early morning
email...its appreciated.
