The easiest way to do this is to purloin the schematic of one of the
transponder ramp testers as they all show altitude and mode A. The IFR 600
is a bit complex but some of the simpler units could probably be cloned
without too much trouble. The RF portion could be removed from an older
transponder that has bit the dust, mainly because the cavity has died in the
transmitter, the receiver should still work and could provide the decoded
pulse train.Use the decoding from the ramp checker. this will give you a
portable unit to put in any aircraft.
