Ernest: you could use a Garming GTX 327 transponder, but you can also use the Dynon Serial to Gray Code converter for $80 and drive any transponder with it that you can get. A Terra transponder, if you can find one, might be an expensive way to go driven by the converter.

Subject: transponder recommendation
Transponders seem to be like hammers. Everybody needs one, and within
very wide limits it's hard to tell one from another.
I'm going with the Dynon EFIS, and it has serial output for an altitude
encoder. If I buy one that accepts serial input, I won't have to buy
and maintain another piece of equipment to produce the Gray Code that
most seem to want. Other than that, I have no extraordinary
requirements. It'll squawk 1200 nearly always. Maybe an occasional
7500, if I have to point the nose at the beach instead of the mountains,
because the wife is with me. Power is a n on-issue. I live in the
crowded east coast, and the annular slot antennae I built is supposed to
give me 6dB of gain in the direction that ATC will be (down).
What is a good choice for a cheap, minimalist transponder that accepts
serial input?
