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 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 appreciate any 500kHz WSPR reports today. 73s Roger G3XBM -- http://g3xbm-qrp.blogspot.com/ http://www.g3xbm.co.uk http://www.youtube.com/user/g3xbm G3XBM GQRP 1678 ISWL G11088 --0016e6dbe59f20b89c048972bec0 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable In the next few hours I've a new experiment on 500kHz WSPR using my ea= rth electrode "loop".
