Recently, I noticed that when the PTT was used the oil temperature number as 
well as the outside air temperature number went down.  Took me a few tests to 
realize what was really happening and, yes, when I talked on the radio the 
numbers on those two instruments, along with the aforementioned fuel gauge 
numbers, changed.

You are not alone.

I have an EPI 800 (VM1000 forerunner) and all of the temperatures go wacky 
during transmit on either the Garmin 430 or the Terra Comm.  These seem to be 
especially sensitive to VHF RF.  Most temperature leads are shielded and so 
is the computer.  Other composite aircraft with VM1000's experience the same 
problem to varying degrees with King or other radios. I join with you in 
seeking a solution!
