To make something universally acceptable in the US, if it only works between
gliders it'll have to be cheap and small. Such a device would be much better
received if it warns of both power and glider threats.
I hope some clever person will modify a Zaon MRX by adding another,
perhaps externally mounted, RF "front end" that transmits an ID code and
the altitude every few seconds, then listens for other units. The
estimated distance (based on the strength of the received signal) of the
"threat" is displayed along with the transponder derived "threats". The
developer would have to do some reverse engineering on the MRX to gain
access to the altitude signal (or just use another pressure sensor) and
to mix the info into data stream to the logic/display, but could end up
with a small, cheap enough, add-on to the MRX. Ta da! Transponder and
glider proximity alerts in (maybe) one small box.
Or, a person even more clever might convince Zaon to do it instead.
