If you could SEE my TX, "antenna" and ATU you would realise how amazed I am
at this report from G3XVL. My antenna is literally 15m of low horizontal
wire with about 2m of it vertical, a central heating ground and an ATU on
the bedroom table made from a ferrite rod and fed with 700mW from a
2N3906/2N3904. This proves that 500kHz is possible with a
*really*minimalist station. I can only imagine what will be possible
effort on my part.
Well done - it just shows what can be done with RF and a piece of wire....
Assuming your ERP to be around the ~mW level we might be in with a
chance even up to Shetland, given some suitable conditions.
I've been doing some tests on 5MHz recently and have been receiving
stations using TX powers in the milliwat, and sub-milliwatt, range.
I've received G4ZFQ using TX power of 0.3mW at a range of 1061km.
Obviously it's not fair to directly compare 5MHz and 500kHz - at least
it shows what can be done with really low ERP.
Please leave the WSPR running overnight and let's see what turns up in
the wee small hours.
