Hello Mark, On the Mixw program, for RTTY 45 bauds, it is reversed internally, to keep compatible with traditional RTTY which is transmitted in LSB, if you are in USB. Multipsk does the same. So with these softs, you must stay in USB for all digimodes (including RTTY 45 bauds) and all bands, this to simplify the operations.

I think it is because many of the sound card programs give you mark high and space low when the rig is using USB. A newbie asks which sideband to use and someone invariably says LSB. USB/LSB depends on which software package that you use and its defaults. I use MixW and to get mark high space low you using the defaults with AFSK, the rig should be set to USB. I don't think many inexperienced operators actually check to see what RF frequencies they are actually transmitting. 73, Mark N5RFX
