EGT and CHT jump when xmit

[pksgwfac6v]

I noticed today (only because I got a CHT over-temp warning in my headset) that when I key up either com I get an increase varying from 50 to 100 degrees on both the CHT's and EGT's; all other sensors are stable. Only the 8 thermocouple inputs do this. The other 'cowl temp' thermocouple connected to an general purpose input is stable too. All the EMS floating or unused grounds are grounded. Could it be RF? :-?

What's up?

Contact support directly, if it's what i think it is then the 'fix' is simple

Jake - tell me. "if it's what i think it is then the 'fix' is simple" The 3 hour time change means I have to wait.

IF you are satisfied that there are no bonding issues with Com antenna & grounds then an email to support should suffice

The best solution is for us to see your EMS module for a change that solves this when you have some down time. Our support team can help with that at 425-402-0433.
