0ca6cbb575 wsprd: improve decoding and reduce the number of false decodes 
Hashtable entries now include the 4-digit grid obtained from the most
recent Fano decode of the callsign. The stored grid is used to validate
OSD decodes. OSD decodes of type 1 messages are accepted only if the
callsign is present in the hashtable and if the grid matches the grid
stored in the hashtable.

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
