Re: [wsjt-devel] RC4 v RC3 decode

Al, RC3 can decode both 75 and 77 bit transmissions, RC4 can't that could be the reason. Neil, KN3ILZ On 11/25/2018 2:08 PM, Al wrote: I have been running both RC3 & RC4 on the same PC decoding the same digital audio stream. At time I have noted that I get decode for 77bit station in RC3 tha

Al, This is expected behavior. Since RC4 does not decode 75 bit messages, it cannot subtract them. Thus, RC3 will often be able to decode a 77bit messages on the second or third decoding pass, after it has removed interference from 75bit messages. On the other hand, RC4 will not remove the inte

I have been running both RC3 & RC4 on the same PC decoding the same digital audio stream. At time I have noted that I get decode for 77bit station in RC3 that do not appear in RC4. I can reproduce this playing back the same wav files in rc3 & RC4. RC3 decode RC4 decode Also noted whe

Several time now I have had RC4 hang ( stop decoding ) with the 'Decode' button highlighted.  The first noticed condition is that nothing is being decoded to the band activity window ( which would suggest that there are no 77 bit signals ). However, stopping and restarting RC4 produced 77 bit d
