BPSK is the norm, as it is effectively 3dB up in S/N over QPSK. If the link shows burst errors we transfer to the QPSK mode which is targetted against that sort of interference. There are no other parameters to set, just remember that the Tx tone setting can actually cover the whole of this LF band over its 200 - 2999 Hz range so be carefull if you change it! Be listening at 2000z when I can. Andy G4JNT
