[digitalradio] 2 Meter FM Digital Modes
Is there anyone out there who is active in using digital modes on 2 meters? I would be especially interested in experiences with digital modes such as MFSK and DominoEX. There has been a number of presentations on this particular aspect of the hobby and it would be interesting to know how what is being used for equipment and software. 73 philw de ka1gmn

I'm limited to 25W out of a Moxon, and I'm down in a floodplain where LOS isn't particularly good. Want to set up a sked? -- Mike Andrews, W5EGO mi...@mikea.ath.cx Tired old sysadmin

Phil, We have been running a 2 meter FM net in FM02 using DominoEx 8 with great success for over a year now. Various transceivers are used, such as FT-897, IC-746Pro, IC-2000H (FM only) and others. We have had checkins from as far away as 200 miles. Antennas are all horizontally-polarized beams. Local stations mostly use 2-element quads and distant stations use 14 dBi or greater antennas. Software is either fldigi, Multipsk, or DM780. Many signals are under limiting and under the noise threshold, but by using DominoEx, we still get good print. The mode is very tolerant to mistuning (unlike MFSK16) and fairly resistant to multipath interference. 73 Skip KH6TY Phil Williams wrote: Is there anyone out there who is active in using digital modes on 2 meters?

In my reply, IC-2000H should have read IC-2200H. 73, Skip KH6TY Phil Williams wrote: Is there anyone out there who is active in using digital modes on 2 meters?
