Re: LF: ERP DISTANCE ETC

[Roger Lapthorn <rogerlapthorn@gmail.com>]

Mal,

Thanks again for the great encouragement. Would you prefer we just watched TV instead and gave up the hobby?

Here, I've no interest in running high power on any band, rather I want to see what I can achieve with low power, simple rigs and simple antennas. If this results in my best DX being only 20-30km then so be it.

As for your comment on earth antennas, I beg to differ. There is still a great deal to be explored and understood in this area on all bands from sub-9kHz to at least 500kHz.

Lots of figures appearing on here at present are guesswork and misleading. This has happened in the past trying to guess who was running what power, then the conclusion was + or - 6 to 10 dB wich is nonsense ie could be !W or 4W or !W or 10W. For those complaining about no room for large antennas, use the best elevated antenna you can get up and run several K/Watts to achieve the required ERP.

Earth antennas have also been tested in the past are only useful for Cave radio communications, the wheel keeps being reinvented here on LF.
