It would make a lot more sense if someone would engineer a low cost ADSB
compliant transceiver that would interface with a PDA. Then eveyone could
go nuts developing software that would be able to identify not only gliders
but also power aircraft. Once the FAA starts installing the necessary
ground equipment, we'll even be able to see Mode C transponder equiped
aircraft using the ADSB version of TIS.

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.
