Made some useful progress on packet radio today. I managed to access a node in Scotland and one near the south coast on 40m, 300 baud. This was using QtSoundModem on the Linux box connected to the FT450D via a Signalink, fed into the random length wire in the loft. Access was via EasyTerm running on the Windows PC at first, but then I managed to compile QtTermTCP so ran that on the Linux box instead. A bit of fun but it proves the possibility of using 40m to interconnect where there is currently no VHF or UHF paths here.
Fingers crossed once I get some wire and metal in the air things will only improve.
