G'day Stefan and Edgar, My house is on QF44OX00OR and the property extends to QF44NX (50 acres or 200,000 m^2). I do have permission from some neighbours to lay wires into their properties, so an ext

Hi Dimitris, Interesting, theat LIPD class. So you could even try higher frequencies than 8.3 kHz. Here we are not allowed to transmit above 8.3 kHz. However, i have a special licence to transmit arr
Hi Marco and Stefan, Competing with NWC Harold Holt would be insanity, regardless of the regulation, that's a frequency to certainly avoid :-) You must have a much larger antenna than me as in my cur

Hi Stefan and VLF, well, I am now officially hooked! My signal on 29.5 kHz (VLF's edge) has been detected 22.3 km away in Canberra by Dale VK1DSH. Only casualty is the russian mica capacitors (K31-11
Hi Dimitris, My congrats! That is a good success and progress! Can you tell more details? How much power was used? How much antenna current? Was it the 3 turn loop? What type of receiver was used on
Hi Stefan, Yes, see answers below! The amplifier output power was about 50 W. Calculated current based on measured parameters about 2.2 A RMS Yes! E-field antenna (miniwhip) to an upconverter and HF
Well, what do you know! The unexpected losses are not just the capacitors (their contribution is probably small). It is also the coaxial cable that I used between the antenna feedpoint and the ampli
Hi VLF Congratulations Dimitris :-) Anybody mentioned an activity rush in VLF ? I'm working on this right now https://www.dropbox.com/s/1vkmlm8kn80688l/IMG_20190210_104522_952.jpg?dl=0 73 de Luis EA5
Hello VIGILANT, You are going to grow a sunflower and use it as an antenna? That's, errr, different :) A change from wet string! -- Best regards, Chris mailto:[email protected]
Hi Luis, Looks good! My first large loading coil was my laundy basket. My wife wasn't terribly impressed but for a period, it served both as loading coil and a laundry basket :-) 73 and good luck wit
