Re: Bare bones WSPR
- Hot shit FM radio works! I bought a computer didn't think i just put another transmitter on the shelf!
Am i correct in thinking that a TNC could be eliminated, and the Rpi just generate and send its own aprs packet?
Maybe the first raspberry pi to transmit CW on the Ham radio bands!
- I haven't worked out how the modulation is done. WSPR is fine because that is pure FSK but APRS would be AFSK on FM.
But you can do APRS on a Pi using 'soundmodem' and 'xastir'. I ran it together with bluetooth and my GPS puck, but can't really think why I would want anyone else to know where I am!
- APRS works best when you can receive and transmit signals.Can anyone confirm/comment on the power output, its got to be low!LPF are must I knock out my DTV when transmitting on a 2m jpole!Thanks againMathison kj6dzb
