Howdy,
I have an Aeromech 8140B20 encoding altimeter with a KT76 transponder.
Mode C is intermittent with ATC. Is it more than likely this is an
altimeter problem or transponder problem? Sometimes when it is not
reporting, i cycle the transponder off then back on and it starts
reporting again. Thanks in advance,
Brian
Also, sould an aeromech and aerosonic encoding transponder interchange
as far as the connections are concerned?

I've had this problem. Luckily each time its been right before our IFR
cert. My avionics guy says that there is some timing thing in the
transponder and it gets out of sync making it intermitant. The
avionics guy can tune it up and it will work great.
