Hi Alan, I think you have struck the nail on the head Alan. Current in = Current out is probably only true if the coil is very short, i.e. this is just an approximation to the truth, which breaks dow
Thanks Dick, That sounds like an interesting station. Perhaps he needs a different type of antenna for receive? John, G4CNN A good strong signal from LX1PD this afternoon. This is the first time I ha
Hi Tom, Very amusing :-) for us Brits, but if we had to write our emails in German, I bet we'd make many more howlers, hi :-( Nevertheless great fun. John, G4CNN And before Andy complains - the origi
Hi All, Dick PA0SE mentioned recently that radiation from the loading coil is approximately equivalent to the radiation from a piece of wire of the same length. This must surely mean that the reducti
Hi John and Paul, I use a version of the KI0LE loop for receive. There is a continuous buzz on the vertical from some local power lines probably under the site here, which makes it very poor for rece
It may be premature, but it looks like congratulations are in order to John and Laurie for something which everyone thought was impossible just a few months ago. Hope it is repeatable. 73, John, G4CN
Hi Alan, Yes I heard this station today, but thought at first, that I had mistaken the call. I heard him first, like you, working Christer, whom I could hear actually and later working F6CNI, first i
Hi Guys, By risking life and limb at the top of a precarious ladder, cutting off as much of the surrounding greenery as possible, I have further reduced my apparent "Ground" resistance by a further 8
Hi Mike, Having had NTL cable Digital Plus installed here some months back, I can confirm that no new QRM on 136 has been observed here that could be attributed to that service. I do not use the E-ma
Hi Laurie, Jim and Mike, Despite high level of QRN good copy of QSO between Laurie and Jim at 19.00 UTC. M0BMU 559 G3AQC 569 Laurie distinctly stronger here in Reading. I found narrow CW filter helpe
Hi All, For those who are unaware of the maintenance program, MSF annual maintenance is undertaken in July. German DCF77 and Swiss HBG services also have down times for maintenance. Their schedules a
Hi All, The following stations are allocated to this range of frequencies: 171 Russian transmitter at Kaliningrad 1.2MW well received here 171 Lvov, Ukraine. 1MW (not heard) 171 Osipovicy, Bielo Russ
Hi All, Trying to find out more about near field effects, I have read that the transition from near to far field happens at the "Rayleigh distance", sometimes called the "far field distance". An esti
Hi All, When Andy queried the formulae yesterday, I later recalled the article in the first edition of the LF Experimenters Source Book, by Lloyd Butler, VK5BR, where he states: 1. The electric compo
Hi Andy, I can manage the maths, although the arithmetic always seems to go wrong, but not being a radio engineer, the formulae are not very familiar. Can you point me to a good source. John, G4CNN O
Hi Steve, Hi Vic, I looked through my list of stations and found that I have heard Vic at least once, so you are at least getting as far as Reading. Unfortunately I don't have a record of the date no
Hi Dave, Yes you are right, I was using a program to decode the CW, although I can now manage to read by ear up to about 20 wpm on a good day. Regular listening on LF has improved my CW enormously af
Hi All, SAQ received 599 here using my KI0LE loop. Unusually for this frequency there was strong QRN of a type which we have often on 136 - what I call the "crumpling a paper bag" sound. Before resta
Hi All, Thought I would look at the new frequency for SXV reported by Costas, and found it overwhelmed by a very strong and wide signal at 123.69 kHz, which is the frequency used by DCF42. However th
Many thanks to Daniel for such an interesting explanation and to Andre for the translation. Judging from the other contributions, it looks as though the thinking has started in earnest for the first
