Make sure the radio is locked into the case positively. Push firmly while
setting the locking screw. Also check to see that nothing interferes with
the radio sliding to the back and engage the plug 100%
Experiment by moving the radio in and out a millimetre or two to see if it
makes good contact with the plug in the back.

Before a test flight yesterday I noticed I wasn't getting anything out
of the radio speaker in my not-yet-one-year-young ASG-29. Volume up,
squelch down, nothing.

Last spring I had problems with the flap position sensor not working
when the canopy was open. (I think it still has the problem -- I gave
up checking with the canopy up.)

But when I put the canopy down yesterday, the speaker worked.

wtf. This seems like too much of a coincidence. Has anyone experienced
any similar problems in a recent Schleicher?
