The slower speeds are better when the condx is worse, 75 bps and long interleave gets through just about anything. I have not really had to use it at that speed , 1200 bps gets through nicely too. I don't know how good the implementation in RFSM is, my experience is based upon years of daily use of the Harris RF-5710(A) modem so I need to use RFSM for a while to be able to say. Trouble is RFSM just doesn't play very well on linux, it hangs at times.
