Great info. It seems obvious that gliders should have a code different
from the generic 1200 so they can be tracked more efficiently and
separated from other general aviation traffic, but I guess there are
only a handful of places in the US where this is the case. Around the
heavily-trafficked Sky Harbor in Phoenix we mix it with dozens of GA
aircraft on 1200, while in the lightly occupied space further south,
the Tucson Soaring Club have been allocated 0400. Perhaps it's time
for some uniform codes?

By common agreement between Nevada glider operations and Reno ATC,
local gliders all Sqwawk 0440. It works well and then routinely route
traffic around us.
