Thanks for this; I just learned something wonderfully obscure:One correction. The Swift actually has a different FCC ID. An FCC report indicates it is 2AO24-17001, not MH8A. They are still compatible, though.
MH8 is FCC ID for PPS; A is the PPS transmitter.
2AO24 is FCC ID for Shearwater; 17001 is the SWIFT.
