Welcome to the Sebago Lake 75M WebSDR located at Sebago Lake in Maine USA. Please sign in below with your ham call or name!

Also visit WA1STH and K3FEF websdr sites. This site opens to the spectrum display, but you can change to waterfall mode if you wish. The receiver is an RTL_SDR. You can order the same dongle by visiting Mike's K3FEF websdr site. Antenna is a dipole set at about 50ft thru ladder line and an antenna tuner.

For e-mail ....see QRZ. Also I wish to acqknowledge Mike K3FEF (and Steve WA1STH) for his help in getting this site up and running. It would have taken me a month to do what Mike did in a few hours! TNX, Peter....N1PS
