PSKmail as described on http://pskmail.wikispaces.com/
PSKmail is a narrow band mail delivery system for use by amateur radio hams via short wave (HF) communication. It is only available for Linux (it is time to change to Linux anyway…). Unlike PACTOR, it does not use a special controller, you just need a computer with a sound card. PSKmail uses Fldigi in PSK125 mode.
PSKmail has a client/server architecture. Unlike Packet Radio (Q15X25) the PSKmail protocol only allows 1 connected client at the time. Bandwidth (3dB) is 129 Hz!!!
The PSKmail client is written in GTK2 perl. At this moment the applications is a Mailbox (port 24) allowing down/upload of mail from the internet, and downloading information from the web (ASCII text only), position update and station-to-station messaging via APRS(port26) and chat mode (TTY, port 87).
Version 0.4 has enhancements for emergency communications. This means that even if the internet backbone is down, you will still be able to send messages and files from client to client.
Pskmail now also works together with EVOLUTION and other Linux mail clients. You can then use the mail integrator you are used to (any mbox compatible system).
There’s a PSKLive (LiveCD) available to test with. The LiveCD allows one to operate the programs without accessing the hard drive on their computer.
As for Technicians … the 10m Band is the place we can use PSKmail on HF.
