31 May 2016 Assuming it's legal to transmit VLF using earth modes, and this seems an grey area, is anyone using Ebnaut for this communication method? if I tried to master the complexities of it, not
Chris should be able to hear any signal from you, already have electrodes in place about 50m apart and over 4m deep into the water table. Lot of noise on them with several volts from a local mw tx! N
Sounds interesting. I've managed about 50km with 250W and a 700m long wire. But that was in 3.8 mHz, which is fast mode for VLF. But it was one of the standard modes these days :-) Before TXing EbNau
Hello DK7FC, Wednesday, June 1, 2016 Thanks for the reply G4WGT is just over 50 miles away as the crow flies. What's my best way to generate a very very stable carrier at VLF? I have a 10 MHz and 1PP
Tuesday, May 31, 2016 Hello Dave (GW8GLO), Only saw your post below tagged on to the bottom of Stefan's reply to me, I don't see it in my e-mail from the reflector for some reason. I am quite keen to
Hello Dave, GW8GLO, Tuesday, May 31, 2016 You don't see to be on QRZ, how far away fro my home QTH are you? I am IO82qv, UK post code SY13 2BT. Wondering if you are nearer or further away than G4WGT?

OK Chris I have built some time ago a elf transceiver that is sound card based using a usb card. It works from about 10hz to 20khz, needs finishing but it is working. All I need is a good high power

Chris, Some years ago (before my stroke!) I had correspondence with OFCOM about earth-mode (through the ground conduction) communication at VLF. Basically they did not want to know and were not at al
They weren't overly concerned when some of us were trying with normal rf transmission. We had to liaise with the team of storm watchers at the met office but it was all very relaxed Jim G7NKS From: o
That's encouraging as I contemplate the blank NoV application in front of me. It is necessary to supply some detail to calculate things like ERP and field strengths. Tricky without building and testi
Hello Roger and all the other VLF folk, Thursday, June 2, 2016 Sorry for the late reply, work has taken me away from play, but I want to thank you all for some very helpful replies. I am hoping later
