W5OLF WSPR kit
7 November 2014 | by Jay has been working on new versions of his little WSPR beacons. All being well I should receive a 10m 500mW out version in the next few weeks.
Jay is writing the manual(s) and has asked me for my feedback, which I shall, of course, provide. The new version is a single board (again) but transmits continuously, randomising the TX frequency on each TX burst to minimise interference to/from others. It needs several minutes to thermally stabilise but uses the uP to generate everything needed such as the WSPR tones, so no PC is needed. The transmission is started manually on the start of an even minute with a push button. The PA can be separately enabled.
This should be fun. I’ll give more information when it arrives and I get a chance to try it on the air.

I’ll look forward to your report. Have been thinking of playing around with WSPR.
