Thanks Dave - 10 watts into a 140' sloper with a poor ground.
I can't play your recordings - I get the message ' Windows Media Player
cannot play the file'. Any clues?
G3JFS has also been testing this evening with a 579 signal here.

Subject: LF: (500) G3OLB and antenna measurements
Coming in fine in Bracknell Tom on 502.6. 569 peaking 579. Recording
at http://my.opera.com/davews/blog/2007/06/05/500khz-recordings
Been looking again at my antenna impedance today. I have optimised
and calibrated my G3LDO 3-meter impedance meter and now can make
fairly accurate measurements sitting in the shack at the other end of
my 22m of coax. I now know that the antenna resonates at 492kHz and
has a resistive impedance of 26ohms there. If the weather holds off I
shall be doing a few 'tweaks' over the next few days.
