I've been plugging away for several weeks now with no spots from IO74.
I've a raspberry pi with a 1/4 wave dipole and lpf transmitting on 14.0971. The dipole is in my roofspace and facing east/west. I know transmitter power will be an issue but I'm hoping for at least one spot before I go to the bother of making an rf amplifier.
I don't have a rig but I'm getting a good signal via my computer/sdr dongle 20-30m away from the raspberry pi transmitter.
If someone can point something at me or do some wspr receiving magic I would be very happy :-)
