It is on now Chris. QRSS3 on 137.675kHz, but you are orthogonal to the loop and I would not expect you to see me  .....but life is full of surprises!

Hi Roger,

I'm not surprised it works better with an aerial!

Will look for you on 137.675, what time are you starting?

Subject: LF: Earth electrode "antenna" changes: reports needed on 500kHz + 136kHz please

Today I've changed my earth electrode antenna system: instead of running the wire to the far electrode along the garden fence only about 1.5m in the air I've now made the wire form a loop, bringing the wire up in the air some 4m, running it back to the house about 17m to the top of my pole, then down 6m vertically and into the house. This means the area enclosed by the loop part in the air has increased some 3 to 4 times but that part within the ground between the electrodes is unchanged. On 500kHz WSPR I'm ~6dB stronger with M0BMU at 69kms than it was on the original earth electrode antenna.

This evening I'm going to try 137.675kHz QRSS3 beaconing with this new set-up and would appreciate reports.
