Thanks for some real world experiences. I have no doubt that if you are running close to the MUF you can run the high speeds with strong signals. Based upon the published numbers, the signal has to be very good, and often well above tests that I have tried using the RDFT based modes which can not handle much below +10 dB S/N at 122 baud.
What has been your experience using this technology on lower bands for NVIS and closer in communication, particularly in the zero to 200 mile ranges? When it is operating at 300 bps, is that also the baud rate? Would it give you about the same throughput as 300 baud packet and how does the bandwidth compare? 73, Rick, KV9U r_lwesterfield wrote: > > My Rockwell ARC-190 v8 HF radio and a Rockwell Q9600 modem at “the > office” into the SCOPE Command network works very well for e-mail > INTERNET access but I do have access to 3khz wide channels.
