the transponder manufacturer (Becker) "recommends" 250 Watt above 15,000'
but to the best of my knowledge there is no FAA requirement for transponder
power

True?

I'm pretty sure that sailplane owners are mostly installing 175 watt
units and flying them to 18k' (and higher in wave windows). Right?

If this 15k' rule is real, I'm supposing that, since gliders aren't
required to have a transponder except in certain airspace (this
airspace is all below 15k' -- except Class A...) that we're generally
free to install anything we want (except 18k' in Class A?).

Bottom line -- 175 watts or 250 watts?

parts - anybody have a dead one that we might be able to salvage from?)

Eric,

I don't believe that is true. I think that is from the specifications
from the Becker transponders. The Microair T2000 is 200w and specs
say 62,000 feet.
