If gliders everywhere were assigned a separate code, like the 0440 in

The Zaon MRX does not do anything with the squawk code except to
report the host aircraft code. Target tracking and reporting is based
only on signal strength which is interpreted as target distance.
Based on the the designers response to intelligent muting I have no
doubt that intelligent muting based on squawk code would be a non-
starter.

It was a general observation that applies to transponder detectors. I
think it would require less processing power and provide better muting
if the unit could determine which threat was a glider and which was an
airplane.

I would like to hear from MRX-equipped (or similar units) pilots that
fly with other gliders equipped with transponders. I've done a limited
amount of it, and with only a few gliders at a time. By setting the
altitude warning band tighter and ocasionally using the mute button on
the MRX (though I'd like the mute to automatically reset after 5 or 10
minutes), I wasn't bothered by excessive alerts.
