Guido PE1NNZ extended this effort with DMA based PWM modulation of fractional divider that was part of PiFM, allowing to operate the WSPR beacon also on HF and VHF bands. Dan MD1CLV combined this effort with WSPR encoding algorithm from F8CHK, resulting in WsprryPi a WSPR beacon for LF and MF bands. I think you may need to use a beaglebone black instead.
This looks like a real international effort:Ĭredits goes to Oliver Mattos and Oskar Weigl who implemented PiFM based on the idea of exploiting RPi DPLL as FM transmitter. 4 Actually yes if its on the Actually yes if its on the same network it should work, EXCEPT there is a bug in the raspbian kernel that prevents 'Full-Speed' microphone devices working, your ham radio probably is a full-speed device. (Oh yea, and a ham radio license.) The site says you can get 10 milliwatts out. All you need is a simple low pass filter and an antenna.
Ham Pi is a distribution for the Raspberry Pi produced by Dave Slotter, W3DJS. Cheap, easy to use SDR dongles are an immensely powerful tool for learning about radio technology.
Hampi is a Raspberry Pi computer image file that has over 100 amateur radio applications pre-installed.
