GM Rick, I have been listening for PSKmail stations for some time. NVIS could be valuable at times but it would also be useful to have servers available on 40 and 80 meters under current conditions. These servers would be reachable from distances greater than NVIS and compensate for weak propagation in the 100 to 500 mile range.
I think the guys in Europe are way ahead of us with this software. They don't seem to be so afraid of Linux.

If PSKmail becomes popular here in the U.S., we will likely have many more servers than at present. Something that has been lacking with all other systems is the minimal use of the lower bands for NVIS operation. As long as there is a path close to (but not exceeding) the MUF, the signal quality will often be the best, but the longer paths may not be open, when shorter ones are open most of the time. We have at least one group here in my state that attempts to use an 80 meter 300 baud packet BBS but I know they have a lot of retries and probably time outs with the messages not always getting through on NVIS. This means that other protocols need to be developed since PSK250 is probably no better and maybe not quite as good as 2FSK300? Another thought .... is it possible to use PSKmail on VHF? It would seem like a good fit for moderate distance communication, local to maybe 100 miles? Maybe even with FM and vertical polarization, which 99% of active hams already have available? Has anyone tried this in EU or other parts of the world? 73, Rick, KV9U Russell Blair wrote: > Rick, well the only I have heard today was VE7SUN @12:00 UTC, 30m > seems dead hr in Texas. > Russell >
