I have been struggling with a client setup that refuses to properly decode/encode RSID.
I think I am finally on to something. My server is set on USB, 10.147mHz. Same for the client. No functioning RSID with fldigi 3.13BJ under Linux and XP. HRD under XP decoded RSID fine.
However, I can set the client on LSB, 10.149mHz, and RSID works. This effectively inverts the MFSK and BPSK. The BPSK won't care, but the MFSK must care.
Rig is an FT-817 set in DIG mode, normally USER-U. But, changed to USER-L for a working RSID.
