My FT1000MP has developed a very odd problem. So odd that its solution 
is defying the local authorized repair facility in NH.

Whenever the rig goes from transmit to receive the frequency display, 
and the radio, goes up anywhere from 10 to 60 Hz. This transition from 
transmit to receive can occur either via PTT, the MOX switch, or VOX. 
The effect is cumulative so after making a few transmissions I am a 
couple of hundred Hz up in frequency (both the transmitter and 
receiver). The problem is somewhat heat related. It takes 5-10 minutes 
after power up before it happens and then as the rig warms up the 
frequency hop gets larger.  It happens on all bands and I think all 
modes but I'm not entirely sure. I just operate SSB.  I of course have 
reset the microprocessor but that doesn't help.

As I mentioned the local repair facility is at a loss. They have put a 
few hours into trying to find the cause and have come up empty handed.

Anybody out there experienced such a problem?  Any ideas as to solution?
