Steve Franke	cbfcb76193	AP decoding basically works. Make data_dir setting work on the Mac.	2019-02-07 18:48:38 -06:00
Steve Franke	71cb6d9f50	Use 4 different Costas arrays to prevent false syncs as received frames move ... through the analysis window. Add a random 77-bit vector to each message so that tone transitions occur even if the message contains a long string of 0 or 1 (like a CQ). Add alternative sync calculation as an option (sync2), for testing. Add basic framework for AP decoding.	2019-02-05 19:18:50 -06:00
