Very nice Roger, I checked my spread sheet, it is the same signal strength -26dB, as you received me on your Spiral Top Loaded antenna.

Subject: LF: Ground electrode antenna on 500kHz RX (and TX?)

 

This evening I tried listening with my 20m spaced ground electrode pair "antenna" on 500kHz WSPR. To my surprise it received G3ZJO and G7NKS at -26dB S/N.  I'm tempted to try this on TX on 500kHz and see if anyone can receive me. On sub-9kHz it looks close to 50 ohms resistive but not sure what it looks like on 500kHz.

This was the first time I've listened/looked on 500kHz for several weeks.
