I have been looking for information on the CFA antenna and found some on internet. Links to them are found on my webpage : http://www.qsl.net/on7yd/136lit.htm (3 last articles) Who would not be inter
I found only two papers reporting field strenght measurement, one from supporters and one from a dectractor of CFAs: 1) WA6HZT and N6YIP in Antennex (June 2000) report a loss of 24 db respect to the
PROPOSAL TO ESTABLISH A LOW FREQUENCY CENTURY CLUB AWARD (LFCC) By Les Rayburn, KT4OZ ... 0-100Khz (VLF Endorsement): Award would be granted to those operators who could verify reception of stations

Congrats to Peter and Jack. Regarding transatlantic tests : based on the CFH plots there seem to be 2 periods with the best chance on enhanced propagation, one arround 00-02 UTC and and arround 05-07
I would appreciate it if we could keep the LF reflector free of 'commercials', especially if they have no connection at all with LF. 73, Rik ON7YD -- -- FASTNET 2001 Just do it! www.Hamble.co.uk Hamb
600 watts of RF puts about 4 amps into my long wire so if Jack VE1ZZ gets 12 amps into his long wire, he must have 5 or 6 KW of RF! 73, Tom G3OLB Or very low loss : 4 Amps with 600 Watts = 37.5 Ohm l
Hello group, I received the logging results from G4CNN, M0BMU, OH2LX, PA0SE, G3NYK and G8AFN so far (and ON7YD off course). Also got a mail from G3AQC that he will send a 'paper plot' to Alan. I will
OK, let's hope that CFH stays on all night and give it a try ... Datafiles (if possible zipped) can be sent to me, I will sent them to Alan and whoever is interested. 73, Rik ON7YD Cheers de Alan G3N
Hello Bob, I am using the version that was available at the time of the eclpise (11 aug 1999), it has no possibilities to adjust the recording speed or put time ticks on the trace. I will check the l
On Sunday an unusual noise aleted me to a PSK31 signal on 137.6, I swapped programs to see Geri just finish working DL7YA on X-mode, and then continue with Wolf DF0WD also cross-mode. Hi Geri, I cou
In order to get a better understanding of transatlantic propagation on 136kHz it would be interesting to record the Canadian Naval station CFH (on 137kHz) on a number of (European) locations during t
I got already some direct replies on my previous mail. The aim would be that the CHF signal is recorded at several locations (all over Europe) during the same period. I think that we should take a ni
Last friday I took advantage of the fact that CFH was transmitting a steady carrier to record the signal using the eclipse software of ON5OO. The recordings of Alan and me overlap from 00 to 07 UTC (
Hi Rich, i just had a look in the junkbox ... nothing arround these frequencies here. If you don't find the 10836 or 10564kHz xtals you might consider using a xtal on the 3rd overtone, that would be
Hello Bill, Congrats on the QRSS reception of LEK. A distance of 1500km seems very good for just 1W input. Would be interesting to know at what time you copied LEK. CFH (on Canadian naval station on
Hello group, I saw Jim (M0BMU) with a solid 'O' beaconing on 71.65kHz friday night. I could heard the signal going on and off, but QRM/QRN was to bad for a normal CW copy. John (G4CNN) seemes to have
My experience is that the core material is not so critical for a transformer. In my PA (450W out, variation of the G3YXM design) I use a 'double-U' core that was slaughtered from the HV transformer o
