When or how do you use the FS-1052, Appendix B modes? My current understanding is that FS-1052 is a subset of the MIL-STD-188-110 modem and you can then select the default speeds and maximum speeds, etc.
Isn't this completely legal as long as you set the minimum and default for 75 bps and the maximum at 300 bps? If these modes are as good as has been promoted at the currently illegal speeds here in the U.S. (> 300 bps), they should work quite nicely for the "slower" speeds up to 300 baud, since the slower speeds are going to have the most robust signals possible with these modes. It seems very odd to me that we are not hearing any of this on any digital groups and yet the ALE linking group is recommending to the ARRL that we use this in place of developing new modes. Can those of you who are using these modes tell us more about them and your experiences? Particularly throughput speeds and robustness compared with other modes? 73, Rick, KV9U Steve Hajducek wrote: > Hi Andy, > > It is the same 8FSK modem, however it uses shorter bursts for calling > and sounding and there is a PSK burst mode as well which uses the > MIL-STD-188-110 modem for generation. > > /s/ Steve, N2CKH > >
