I have been experimenting with a Raspberry Pi Linux computer, using it as a
transmitter. The spectral purity is not very good, but it does work as WSPR
on a lot of frequencies. The power out is about 10 milliwatts, give or take.
Use of a band pass filter might clean up the output.Does anyone use WSPR on 13.56 MHz? http://soldersmoke.blogspot.com/2013/03/wow-raspberry-pi-as-rf-transmitter.html 73 jimvm wb6qzl
