The range of audio levels coming out of the SQRX on SSB is difficult to 
match to the FM transmitter. If you recall we've had problems with too 
strong stations on SSB up causing the FM transmitters to behave poorly 
and overdeviate. I can only imagine it would be 100 times worse on Field 
Day. It's a good mode when everyone behaves though!
