Bill Somerville	cccb38dbef	Pass hints to fst240sim, genfst240, and packjt77::pack77 on WSPR msgs ... Due to an ambiguity with message encodings between 77-bit QSO modes and 50-bit beacon modes with message types 13.n3 4.0 and 0.6 a hint needs to be passed to ensure the right encoding is emitted. The hint only effects ambiguous messages, others will be encoded strictly according to the message content.	2020-07-17 19:09:21 +01:00
