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.
