I just don't know of a permanent server on V/UHF FM but there are no reasons not to have one. A point I noted in my tests: as described in QST a year or so ago, the FSK modes (THOR8 and 22, MFSK16 and 32 as used in Pskmail) provide a surprising sensitivity in FM, close to the sensitivity under ssb. This means that exact frequency alignment is not necessary (which can be a problem in ssb on VHF and especially in UHF) and this should allow Pskmail traffic to go through repeaters quite well too. Hope this helps, 73, JohnGreeting- Well then since I have an abundance of 2 meter FM equipment and I can only use one 2 Meter HT at a time I think between job interviews and other things I have to get done around the house I will dig out one of my older FM rigs, maybe my OLD Drake TR-22C and set up New York City's first VHF pskmail server. Of course who am I kidding.......with the way life tends to go it may take more than this week. I also have several older laptops around....mostly with older versions of FreeBSD installed. I wonder if anyone has any real world experience on what the minimal pskmail server needs? I note that fldigi needs X11, which is unfortunate as in server service running an X application is pretty much a waste of CPU cycles. I was looking at trying to set up a server on something in the Pentium II 100Mhz range, just because I have several laptops of that era just gathering dust. They all have sound and the sound works fine for playing/recording ogg audio files. 73 -Brett wa3yre
Hi Brett,I have had the server running on a 500 MHz laptop, that was a while ago and I think fldigi has "matured" since then and requires a bit more muscle. At the moment I am using a 1.4 GHz P4 and fldigi uses abt 10-20% cpu. P2 100 MHz sounds somewhat difficult.
Regarding X you can solve that by using xvfb. To start fldigi under Xvfb do the following in a terminal: Xvfb -ac :99 fldigi -display :99& I use screen as display manager and run the server in another "window". 73 de Per, sm0rwo
