For this distance you can use 80 meters day and night, and 30m during daylight. I use 10 Watts and a 4x40m horizontal loop from home, and a 7.5 m linear loaded bended vertical on the camper. This works24/24 for distances from 20-100 miles. During night hours I use the pskmail server in Stockholm, which is 700 miles away.
My 'local' server is 10 miles away, and I can work it day and night with 5 Watts on 30 meters using PSK125. It runs 25 Watts into a dipole. 73, Rein PA0R > -----Ursprüngliche Nachricht----- > Von: [email protected] > Gesendet: 26.12.06 21:48:51 > An: [email protected] > Betreff: [digitalradio] Regional communications ? > > My entry in to amateur radio was via 10 meters and the quest for DX, I > had no real interest in "local" communication.
