I often hear your beacon at good strength -
best times for a sked Chris?

Hi Rog,
Just back from a few days away.
Thanks for Adrian's report which I've QSP'd.
No, I haven't received the MP3 file yet.
The ground system here is a single 2m copper pipe rammed into
the earth at the bottom of the aerial vertical section.
The local water table is high and only about 2 feet down !!
I think my success is due to a 2.5 m x 10m metal corrugated roof
which runs under the aerial top section !!
I often hear your beacon at good strength.

Chris, Adrian is usually identifiable here
during day, similar to G3UNT, at MDS. You might like to QSP
rprt.
Did you eventually get that MP3 file from last
Sunday [XIZ/KEV].
Interesting F/S results & ur Tx info -
only managing ~300mA [4W] here with high Input-Res / gnd loss
~40R, also tree/forest-loss.
You must have a FB gnd
system.
72, Rog.

Thanks Dave,
I've forwarded your E-mail on to
Adrian.
I'm sure he'll be pleased.
My aerial current is about 0.5
A and the TX puts 4 watts into a 50 ohm dummy load.
Good luck with
the F/S measurements.
