30m WSPR transceiver kit
By now, you probably realise that I just love WSPR. With quite simple equipment it is possible to be decoded across the planet consistently with real QRP power levels. I am always on the look-out for new ideas, although until my health improves I am not in a position to build too much myself. See http://www.knology.net/~gmarcus/WSPR/wspr_v4.pdf for an example of a complete 30m WSPR transceiver.
This is NOT a new circuit – it has been around for some years – and it still needs a PC for the WSPR software. Some TX-only WSPR beacons use microprocessors to generate the WSPR TX messages, thereby freeing up the PC and consuming little power overall. Some sync to GPS to avoid timing issues too.
G3XBM, Will you or someone other ham be building this WSPR rig.
I ask as my building days are well past me.
Hoping your health improves, Vince AF6YG
