I modified three rs-41sg. The problem is that dl-fldigi say checksum error. Also i can’t decode aprs messages, afsk1200 and direwolf can’t decode.

Great blog, btw.

..you have to use the DL FLDIGI software (and not only FLDIGI) and then you have put the check in the upper right corner on RX ID on DL-FLDIGI? For APRS and decoding I use MULTIPSK.'73
