Received at RST 229 on 136 kHz at 1335UTC using a 25 turn 30cm diameter loop (resonant at 88 kHz for cave radio). Not audible on Marconi T. Location is 20 km north of Felixstowe. This message was sen
Another approach, possible with some receviers, is John Rabson (G3PAI)'s logging software, referred to in a previous reflector email ;-) I have written some simple software to control the Lowe HF250
I have obtained a copy of the patent spec for this invention. From a patent spec someone skilled in the art ought to be able to make a CFA without assistance from the inventor. Having read the spec I
Between 1030 and 1045 UTC today, at a rural location about 5 km east of Ipswich, I heard: G3GRO/P (569) workinjg GW4ALG (229) G3KEV (589) G3YXM (569) The RX was a CM Howes DC2000 modified for LF, plu
On Sunday next between 1045 and 1130 UTC I shall be speaking at the East Suffolk Wireless Revival on 'LF Radio - how to join in'. If you are in the Ipswich area please drop in. Talk-in will be on 145
DCF was S9+20 dB on my simple RX and loop, but nothing else heard near Ipswich except _lots_ of QRN. Many thanks to people who did transmit. 73 de G3PAI This message was sent by XFMail --
... It was loud and clear by ear around 0230z (4:30AM CET). Level about 0230z is 0430 CEST, surely? (CET = z + 1 hour, CEST = z + 2 hours) 73 de G3PAI This message was sent by XFMail --
About 30 yrs ago, there was an LF TX at Ongar Radio which (I was told) used a horizontal halfwave on 90 kHz (ish). Do any ex-PO people know anything about it? 73 de G3PAI This message was sent by XFM
In 1961 a retired RO told me of the night when his ship was about to enter port in Alaska. He called the Alaskan coast station on 500 but was answered by a station in New Zealand. 73 de G3PAI the rem
This sounds like LORAN (aka Galloping Horses) on 100 kHz. It does spread (legally - G3JKV? has had it checked). There are two or three tranmsitters in NW Europe, incdluing one at Lessay, on the Frenc

Early in January, I have to talk to a local radio club on progress on LF. Does anybody keep a list of the current DX records? I would like to get in touch with them at the beginning of January to che
Daniel, Si vous permettez, je fais un traduction. [By your leave, I will provide a translation] Although I am an F1 [VHF only] I am interested as an SWL in LF. Here I am building an indoor loop one m
We use this technique of grounding both ends of a wire in Cave Radio work as it enables us to communicate to a greater depth than does the conventional method, which uses resonant loops a metre or tw

Christer, With the figures you give I estimate you will be getting about 100 KV across the inductor. An air-cored coil , of substantial size, would seem to be the best way of doing things. By the way
Long Delay Echo? 73 de John Rabson G3PAI ... I noticed another weak signal had been recorded at around 137.740kHz. It turned out to be sending the same data as GM3YXM/P but with a mystery delay timin
