642540ff8f unpack77 now returns logical variable unpk77_success, which will be .false. if there is something obviously wrong with the message. Still to do: set the flag if the unpacked message contains CQ in an implausible place. 2018-09-12 15:06:26 -05:00

af7feaf65a No need to examine every entry in the hash table. Just calculate the hash of OSD-produced callsigns and see if they are in the table. Add OSD decoding to the deep setting for wspr decoding. 2018-09-10 17:01:50 -05:00

0c60db50d3 Experimental -o option for wsprd uses ordered-statistics decoder. Decodes are accepted only if the callsign exists in the hashtable. 2018-09-09 20:30:23 -05:00
