This behaviour on 500kHz mirrors closely that which we get on 160m. Certainly in the winter months and to some extent in the autumn the nearer continentals are audible on top band throughout the day

Or more likely the 32nd harmonic of the 15.625kHz TV line ocillator rate. UK, UA and VK all use the 625 line PAL standard (though parts of USSR are Secam). The line rate is actually locked to the col
And looking at Dave's site at http://www.wireless.org.uk/links.htm I see he has an out of date link to my pages. Having moved away from BT Internet all my @btinternet.com pages will now come up 'not
Since I have now changed my vertical to a 160m one and won't be on 500kHz until the spring I shall now be unsubscribing from this list for the time being. 73 Dave G3YMC http://www.davesergeant.com
Indeed. With all the problems I had with a small loop on 136kHz and the high circulating currents (20A ish at a few watts) I would imagine on at a 1/18th of the frequency would have an efficiency not
And might explain that when I rejoined the reflector yesterday I then received a whole batch of mails from Tuesday. I thought it was just being nice to me by sending the last 10 messages.... 73 Dave
For once I am afraid I agree with Mal... ROS created quite a stir when it first appeared on HF earlier in the year. Their first suggested working frequency on 20m put it splattering right over the IA
I remember calling you with that big signal from Puckeridge Jim with my 136kHz loop and getting no response.... I was a bit surprised as I was working quite a lot of stuff at that range and further s
It is important to differentiate between 'permitted' as a licence requirement or 'actual' bandwidth. The UK has never had bandwidth (for any mode) specified in its licence for any band, only a genera
Gary First one error - it should be GW4ALG Steve on the links page, not GW3ALG. Sadly no longer on 136, or anywhere else for that matter, as he has totally given up the hobby. I am puzzled by your in
Yes, I am getting more and more confused about how you are using these transformers and what you are trying to do with them. If you are talking about transformers with a tapped primary (designed for
As far as the UK licence it means nothing and he has no authority to add it. Only /A,/M,/P are specified in our licence, anything else, including /QRP, are not allowed by inference. 73 Dave G3YMC htt
It should be borne in mind that all these types of LOPT's are now antiques. Split Diode type line output transformers have been universal in TVs and monitors for the last 25-30 years. So you are real
Multi-hop sporadic E, normal this time of the year Graham, and absolutely nothing to do with any auroral activity. I heard no sign of auroral notes on 10m myself - was down there till around 9pm in C
Not sure that mains transformers are appropriate for 9kHz. Probably better would be switch mode psu transformers (normally operate 25kHz75kHz) and you could probably design what you wanted with readi
