FT-1000MP XMITs 50.125 Whistle

[Michael Valentine]

Hello all!

I have an FT-100MP that I dearly love.  However, it radiates a
carrier that drifts from about 50.121 to 50.134 as it warms up for
an hour or so.  Starts low cold and drifts up warm.  This is backwards
from what any normal oscillator would drift.  The main radiation seems
to come out of the keying jack.  The carrier is about 579 with my Kent 
paddle plugged in.  If I unplug it, the carrier drops to 529.  Covering 
the paddle with my hand drops the signal a few S-units.

The frequency is very stable (T9) short term, and FMs only a few Hz 
under 100 watt transmit conditions.  No button setting or band changes 
or display brightness differences seem to have the slightest effect.

Does anybody know what is causing this radiated carrier?  It makes it 
real difficult to work 6 meter DX on my JRC JST-245 while trying to 
coordinate on HF with the FT-1000MP.

Frustrated in Ohio,
