Just read your mail. I have switched the WSPR= Rx on & will monitor Rx only.

I monitored du= ring your last WSPR test but nothing decoded.

A= small step-up transformer should allow me to better match the earth loop= and therefore increase the ERP some 4-6dB. To make a valid test I'll= run the beacon for periods with and=20 without the step-up transformer to see if a clear pattern emerges. You'= ;ll have to guess which is which.

So, (as always) I'll much app= reciate any 500kHz WSPR reports today.
