While doing other things, I let the rig running with WSPR on 30 meter with 5 watt this morning. My signal is heard all over Europe, and best results are: W3HH Florida, USA, YV4GJN Venezuela (7944 KM) K1JT New Jersey USA and W1XP Massachusetts USA. I used my inverted V dipole antenna.
Julian G4ILO wrote about interference on 20 meter. [link] Now I have interferences on 20 meter what just looks like interference on 30 meter (screen shot from 14.076 KHz JT65A freq.) Not all the time, but so now and then. I don't know what the source is. Some say it is from flat screen TV's, but I don't have the problem at night, but just at day time. Pretty annoying.
