Hi Howard, During the daytime, 160, 80, and sometimes 40 meters are NVIS capable depending upon world location, but for sure 40 meters is usually open for lower angle distances and can be very good. NVIS just means that you can get the close in stations as well as more distant station, so there is no skip zone.
Linux has not been very successful here in the U.S. with most ham computer users. Even the ones who are very techy, such as myself, find it mediocre as an operating system. Several of my ham friends have tried it over the years too and abandoned it. A nearby ham, who is very tech oriented decided a few months ago that he was going to really get into Linux, until he really tried it and realized it just was not going to work for him and he is an electronics engineer. That has been the case with most other hams I know and some of us, myself included, really, really, wanted to like the OS, even with its shortcomings. But it just has not been very practical at this point because like so many things in life, the trade-offs are too great:( 73, Rick, KV9U Howard Brown wrote: > GM Rick, > > I have been listening for PSKmail stations for some time.
