Also S3 here on a 17 turn 80 cm loop designed for cave radio on 88 kHz and not retuned. Many thanks gentlemen for all your efforts. 73 de John Rabson G3PAI Hi All, for what it is worth I can copy a r
Hi all, I have noted again from Peter's description of the Tesla experiments at the Museum, and from John's Earth Wireless web site, that the addition of several pounds (or kgms) of common salt (and
My problem with Morse (I did use it once upon a time) is getting the words down onto paper these days. After 15 years of using word processors for everything, I've forgotton how to hand write fast e

This reminds me of the day I got my licence. It was January and it had snowed the previous night. Excited by the new licence, I had several successful 160m CW QSOs before I found that the antenna was
Has anyone experimented with phase shifted / delayed audio, i.e. with "raw" audio fed to one half of the headphones and a (variably) phase-shifted / delayed version fed to the other half? This remin
Possible Causes: My money is on the increased field strengths being due to fields and currents under the ground surface, resulting in greater effective height of the antenna. Obviously, this needs m

You don't necessarily need one long earth rod. You can try the same total length made up of several short rods separated from one another by at least twice their length. 73 de John Rabson G3PAI Still
I should have said 'spaced by 2 or more metres' In cave radio experiments we find that one x metre rod can be replaced by x one metre rods spaced by 2x or more metres.
To All from PA0SE I thought CW means Continuous Wave. Am I wrong? No, the term 'Continuous Wave' was to distinguish it from spark! 73 de John Rabson G3PAI
