Yes , ref , your 8K test's some time ago , I remember
you reached TH3 ??
You mean TF3HZ? Yes, and 4X1RF. Not only, here is the summary of my /p
tests https://dl.dropbox.com/u/19882028/VLF/VLF_11th_all.png
But that was with 500W on a 300m vertical, not from this tiny antenna
i'm using here in JN49IK. The 300m kite permission expired in the end
of July. So now i'm limited to 100m again.
The ERP is about 20 dB lower here, i.e. below 1 mW. I can't make much
more here, the isolators do only withstand 35 kV rms and i'm very close
to that...
, Gary also had a trace from your signal.
short range ... Kent ?
Well , OP4H test , ground tests have been carried out in
the usa and several miniature test ranges using the
output from a sound card and a remote Rx at the end of the
garden , giving levels round -45 -50 dB with 'real' noise .
OK, in the near field this is much easier as we have seen. Anyway, good
start.
