I have a friend who is interested in Tesla's work and who is looking for papers & books that he authored. Grateful for a direct e-mail from anyone that can provide any suitable links that I could pas
Since the 73kHz tests on Tuesday I have been monitoring at several times a day and find a consistent and steady noise-level that is about 20dB below the signal at 138.8kHz, and about 6dB below the on
Thanks, Dave has also heard me. The problem this end is that I can't hear anyone! I'm trying my old loop and pre-amp now, but all that's doing so far is to re-create the mains harmonics, which are th
Have been transmitting on 72.2kHz but mains harmonic QRM setting the noise floor so not hearing any signals. Will get my loop out of retirement to see if that can improve things. Will call 15 and 45
All, I'll tentatively say that I will operate from about on 72.200kHz, though I suppose if I cause QRM I can count it as success! It will be a manual changeover from TX to RX. Won't be on the Interne
Don't hold your breath, but I spent yesterday resonating my aerial for 73kHz so plan to give it a try for my first 73kHz QSO. The effort will have it's limitations in that I seem to be only able to g
Plenty of activity, with approx sig level above estimated avg noise here in Newport Pagnell: G3AQC 30dB G3LDO 30dB G3XDV 20dB G3GRO 20dB GM0MRF 10dB Saw some other transmissions, but wasn't around at

At last the high-level QRN has stopped. Transmitting around 72.0 from house over 100m coax to aerial loading coil by which time most of the power seems to have gone! Receiving G3XDV QRSS... and one o
Just to inform that I plan to see if I can get a little more (like some!) current to flow into the aerial during tomorrow's "reception window" on the band. I'll probably start tuning around 8:30am an
Decided to "call it a day" after the CW transmission at 1830BST - the QRSS keyer having failed. Thanks to Derek, Laurie and anyone else who listened out for my test. 73 John, G3WKL --Original Message
Hi, had an interesting but disappointing effort to transmit down to Laurie, G3AQC, this afternoon on 73kHz. It's really my last attempt before we loose the band at the end of the month. Clearly, the
