Hello All, Below is a quote from the Stefan's web page concerning his latest "Dreamers Band" DX contact Congratulations again Stefan. "100m Vertical wire antenna, coil/antenna voltage was abt 15kV rm
Yes... That coil inductance number was what I calculated based on a guess of what the "C" would be. Now that I can read the capacitance... the inductance would be higher. Sadly. My next step is to se
Alexander, I just tried to email you an alternate address. My email to you got bounced also. I do not know what the problem is. Please try email to [email protected] Folks I am sorry for th
Hi Jim Thank you for the formula for calculating "C" of a wire. Also the information about adding additional wires is valuable. There are 2 methods I could try with my 55 meters of wire. With the use
Alan, There is no free lunch. It sounded too simple to be true.. But installation of the system you describe would not be very difficult. Keeping it stable and in one place as you say would be proble
Hello Folks, Thank you for all the help with measuring my antenna impedance. Let me explain further what I was using to measure with and then add some updates. The homebrew bridge I was using was bui
Hello Stefan, Thank you for the response. I hope to increase the "C" with top wires? The coil I have calculated is very large as you say. Using one of Reg Edwards programs, it appears that a coil 1.2
Hello, I see from previous posts that a number of aprox 6 PF what size wire is this for? Increasing wire size should in "C" as should several conductors in parallel spaced a few feet apart. PauLC W1V

Yes I got Alexander. Thank you!! Paul C W1VLF --Original Message-- From: [email protected] [mailto:[email protected]]On Behalf Of Alexander S. Yurkov Sent: Monday, M
Hi Stefan, Thank you ! I forgot to explain that I have additional "L" at the antenna. See the link again as it is updated with the info you have asked about. http://rescueelectronics.com/9-Kilohertz.
Here is an update on the W1VLF 8.97 Khz transmission system. I have in the last week built and installed a variometer into the loading coil. To resonate the antenna I find that I need 395 mhys. The v
Stefan On page 60 and 61 of the Low Frequency Experimenters Handbook Peter Dodd RSGB there is an example putting a coil near the top of the antenna In this case the transmitter is on 137 Khz and a of
Hey Guys, Here are some pix of the completed inductor for 9 KHz Jay W1VD will set up his receiver to see if a tiny bit of data can be passed from my QTH to his More on what happens. here is the link
Stefan, Rik, Dreamers Band Folks. Thank you for all the references on places to look for info on the LF/VLF antennas and the elevated coil. Shortly I will leave to check out several possible formers,
Hi Jim, Thanks for your insight on the topic. The proof is in the pudding I guess. I will not know the answer until its actually try it. Right now I need to get my coil wound get on the frequency and
Stefan, Thank you for the explanation I will read several more times . To better understand. Thank you again PauLC --Original Message-- From: Stefan Schäfer [mailto:[email protected]
OK Rik, "But, with or without trees:, the better the ground system (rod's) the more efficient the antenna will be." SO.... Is it then possible to say that the current I see in the single grounded rad
John, Yes.. I do fid that interesting! Do you have anymore detail on how you are making this observation?? PauLC W1VLF You may find this of interest. We have found at 87 kHz (cave radio frequency) th
