OK Roger

I shall look for you. As a reference your signal at approx. 13:00

2013-01-06 13:10 G3XBM 0.475652 -14 1 JO02dg 0.01 G3ZJO IO92ng 79 270

Seems you are not decoding me at the moment.

Later today I intend to transmit for several hours using my 20m spaced earth electrode "antenna" normally used on VLF. The wire between the 2 electrodes is at most 1.5m above ground and runs between the house and a ground stake at the bottom of our small back garden. Signal levels are likely to be down on those obtained with my 6m long (1/100 wavelength) vertical, but I am interested to know by how much.

So, if you copy my WSPR signal later today at a lower level than usual, you know the reason.

I expect to set up after lunch and start TXing around 1400gmt.

WSPR reports on the earth probe antenna will be MUCH appreciated.
