Hi Tommi;
That was our experience as well with RFSM8000 here in Canada. I could pass a 30K .jpg file in about 3.5 minutes under good conditions. I am far from knowledgeable on the US regulations but apparently RFSM runs at too high a baud rate to be a legal mode in the US. It is a pity since it works so well and does pass emails directly to the internet through a gateway . As you pointed out, it requires a pretty strong signal to work. Not sure if any more work is being done on this mode over the past year or so.
