Hi Steve I suggest you take a look at the following URL- it is VERY inexpensive and I believe will do everything that you could possibly want. http://www.qsl.net/zl1bpu/ There's a simple hardware de
I heard what I think were Jason signals on 137.5 at about 09.40 clock time this morning. Can anyone confirm who (if anyone) was transmitting and the power they were running? Thanks Steve G8GSQ
Apologies if this is old information for anyone, but www.wires.co.uk might be of interest. Every size of copper wire you can imagine, and Litz (they call it stranded enamelled wire). For those with w
Steve, I'm struggling with a poor set of options for an aerial at this house. The greatest vertical section I can get while still allowing top loading is 8-9m, but the lower 3-4m would be up against

Hi Steve that is not unusual for any long pole supported at a clamp with "line" contact. I presume you were using "U" bolts ?? snip Yes - your description of the installation is quite accurate and i
My aerial experiments have come to a halt. I was using a lightweight fishing rod (fishing people call them whips) to support a vertical wire. The rod is neat cosmetically and easy to handle. I had it
For some time I have been "playing arround" with an idea for an alternative antenna. I intend to give it a try when I find some time (during winter), but meanwhile I have put the idea on my webpage :
That's in comparison with horizontal top loading. If a drooping top hat is all one can manage, it's generally better than none at all. However, consider that the far field radiation will be proportio
top-load It "works fine" to be sure, and it's possible that this is the only physical shape possible for your surroundings, BUT did you verify that there is no loss from drooping the top hat radials
Hello ... I challenge that. My umbrella antenna 18m high with 5 pieces of top-load radials sloping downwards (each about 7 m long) works fine (see sketch at http://www.qru.de/station.htm), with an a
Hi all, a quick crude calucation from Ed's drawing suggests that the Rrad of the aerial he was using could well have been in the order of 6 to 7 ohms. How many broken computers from people drooling
Go for several routes. There's nothing to say we have to stick to one: 1 national society magazines such as RadCom and Radio REF 2 this reflector 3 specialist periodicals such as Sprat 4 Practical W
Thanks to all for their comments on and off list - I'm very grateful. Having given up vhf contesting I was hoping longwave would prove interesting and so it is, with lots to learn - and a nice bunch
Can If the frequency is very close to 136.0kHz, this is something that has fooled many of us into trying for hours to read the 'Morse'. It is probably the result of a mix between several other stati
Sorry if this turns up twice, but it's some hours since I sent the original. Listening sporadically and briefly today (Sun) morning and yesterday evening I could hear a keyed beacon at about 136.0kHz
Yesterday evening and this morning I'm getting a keyed beacon at about 136kHz, just below the level wher my ears or the computer can decode it. Can someone tell me what it is, or is it a phantom? Tha
I got it working without any problems, but got strange results. I tried the 'T' antenna, just changing the frequency to 136kHz. The calculated radiated power is -26W and it signals errors. I payed ar
