For those wanting to correlate solar flares with enhancements in sky-wave reception at LF, may like to look at: http://moondog.astro.louisville.edu/flares/info.html Mike, G3XDV (IO91VT) http://www.de
Spent some time working on my new mast which should be up in a week or two. Listened on 136kHz when I could. Very strong signal from the US RTTY signal so it looks like the DX season has started, des

A really interesting discussion, and some useful data, though as with all computer simulations it is vital to include some practical knowledge so as not to be misled by the results. Thanks, Dick and

Spent Saturday getting the parts for my new antenna so no activity. Sunday 19 September In the morning, I heard HB9ASB (549); G3BDQ (599); PA2NJN (539); G4GVC (599); PA0SE (579); DJ5DI (539); DL3FDO
Spent most of this weekend putting into action plans for a better antenna (both physically and electrically) which I have been drawing up for some time. The result - still an inverted-L -is a slightl
I commented that my antenna current had gone down following the change from one top wire to three. I have re-engineered the far end and have improved things. It seems that the far end insulation was

High winds this weekend but the new antenna stayed up well - the old one would have needed to be lowered. Saturday 2 October Very low noise but also low activity. Heard G3YXM (599); PA0SE (579) Worke
I have a sked on the 73kHz band with Peter, G3LDO, on Tuesday morning (the 5th)between 0700 and 0745UTC. Frequency will be 71.90kHz. Any reports would be welcome. I will be testing on Monday evening
A couple of tests on 73kHz have flagged up a possible problem on ther band. I transmitted for some of the evening of Monday 4 Oct on 71.91kHz but was not audible with G3YXM. I also listened for Dave'
Peter, G3LDO, and I transmitted beacons on 71.70kHz this morning in an attempt to check whether our abortive tests of yesterday were connected with the noise coming from Rugby. This frequency is as f
My last e-mail referred to a web page showing the results of the 73kHz tests. I forgot to mention the URL - and it was put up in a few minutes so is not yet linked from anywhere else yet. It is at: h
Funnily enough, that is a possibility that Peter, G3LDO, and myself were discussing this morning. The noise appears to decay fairly linearly with frequency, whereas I might expect it to be more expon
Received a QSL yesterday from Walter, DJ2LF, for our QSO last weekend on QRSs. I was delighted to see that it was not only Walter's first G contact, but was also my best DX at 835km - he is at JN59NO
I gather from later mails that the tests between G3LDO and G3XDV may have been on QRSS. If that were the case then the interrupted carriers I heard on Tuesday and Wednesday may well have been them,
