137.675kHz QRSS3 beacon report

The <20uW ERP 137.675kHz beacon was copied again by G3XIZ 48km to the west of me last night. I'm pleased with this report as the power from the PA was less than it was a week or so ago, yet he still managed to copy me. Work is now progressing on the class-E PA based WSPR beacon which should run about 10W from the PA (ERP around 20-50uW).
