Almost a year and a half ago I ordered, built and wrote about a new kit – a stand-alond WSPR transmitter from Jay Wilson W5OLF. You can read it here.
Jay has just announced three big changes to this kit: Continue reading 'Changes & additions to W5OLF’s QRP WSPR kit'»
A few months ago I wrote about a new transmitter kit for WSPR. A receiver kit for this mode is now available from a different source (also available fully built).
Of more significance than the fact that we hams have a new kit available is the idea that WSPR is a great science project for non-hams…and therefore a great way to introduce ham radio to those outside the hobby. Continue reading 'A stand-alone receiver kit for WSPR'»
Those seeking further info on W5OLF’s WSPR beacon kit can find it here in the QRP Page section.

It was fun and surprising to see what could be accomplished with a watt, even on the low bands. But I had a ton of wires and a rig tied up to the mode. And I couldn’t use the computer’s sound card for other purposes without disconnecting wires and plugging in the speakers. Continue reading 'WSPR simplification & performance improvements'»
