Hello from Iowa in the US - EN31do, Very interesting. Such technology could be reasonably expected to exist. I agree with your observations totally. Granted that my anecdote is about 10 years olde: a
Well, now that you ask - and this is true - a friend of mine's parents built a bomb shelter back in the early 50s when Stalin was "about to push the button." According to Bill his parents went first
Pictures of the site and equipment would be great to see! Doc. Below the answer from Hans Andor Johannesen -- 73 Hartmut www.h-wolff.de Locator: JO52hp -- Original-Nachricht -- Betreff: RE: Akraberg
Good afternoon, here in EN31do. Please do not flame me. I have the top US Commercial 'Phone license (since 1954 - with radar endorsement), extra ham radio license, and 40 years in broadcasting mostly
Thank you - I learned something today and that makes it a good day. I knew it had nothing to do with receivers of any kind. My misconception was since it was such a powerhouse that its signal strengt
Items: 1. I thought this was a list for people interested in radio and LF/VLF, etc. specifically. 2. I very rarely have posted although I read the list regularly and have been trying to learn. In thi
Ah! Crystal sets! More of the joy of analog.... Doc, Mal, I did build a "crystal radio" with a razor blade as detector when I was 14 years old. It had to be rusty to work properly and even then it wa
Hello from Iowa, EN31dx! Perhaps you have already received this information, in which case I apologize for repeating it. Pretty exciting news for me - on the verge of retirement. Doc Gruis __________
Interesting. Here in the States I have had much better luck in using a capacitor to couple to the telephone lines. The intensity of the noise does not seem to be quite as intense. This has worked for
Hello from Iowa in the U.S. (EN31dx) Two observations: 1. I am very concerned by the lack of apparent cooling whether by air-conditioning or at least by a fan when this ATU is used at QRP levels! ;-)
I really don't know if there is the practice in Europe of directional AM broadcast stations, i.e., 540 to 1600 (or 1700) KHz., but it sure is practiced here in the U.S. The mention was made of the fo
Thank you. At the present all the U.S. allows is i watt input to a 50' antenna and that 50' includes loading coil, and transmission line, and such. I have been partial to some off center or center l
I have been a bit out of the circuit the last couple of days regarding this thread. Yours seems a very thorough investigation. Please excuse me if I revert to my MW BC experience. At a number of inst
Hello from Iowa in the U.S. A question for you: what is "Clover?" That is a new one to me. Thanks in advance and 73, Doc Gruis. _____________________________________________ Alan Melia wrote: A very
Ahhh! I wish I could fulfill your request and send a comparison between the old and new antennae! But, of equal importance to me, is to find another radio-active person subscribing to me theory that
You might check the LWCA homepage. It seems to me that there used to be an experimenter located in Cedar Rapids, Iowa, USA, that operated in the audio range and that he was a member of that group. I
100%. I meant to be brainstorming more than advising. Doc. The problem with loop to loop operation at these frequencies is that is subject to the inverse cube law of magnetic induction rather than an
Dave and all - Try this URL for the document. The list indicates it is indeed there. I put "sky-wave" into their search spot, and there are more than one matching references. http://www.itu.int/plweb
Andre - Okay. You are oh so right! I copied the URL and pasted it into my previous post so for once it was not my terrible handwriting. But if you go to this address you reach the ITU: http://www.itu
Ahh - are those "O" symbols the letter "O" or the number "0?" -;) On my L.F., 10 meter and VHF beacons I added a "hold" circuit that continues the carrier until the ID cycle begins again and is keyed
