i too had trouble with flaps unrelated to radio transmission.
two weeks ago flaps stopped working - went to cirrus facility which determined a 'relay under back seat had come loose , and
reinserted the same. Flaps worked again but two weeks ago flaps refused to retract after takeoff, would go 100 % back to 50 % light indicated 0 flaps but flaps remained at 50 %. After a while problem cured itself but I am still wondering - no transmission involved. Any ideas ?
