Now it's time for Mal to crank up a few kilowatt into one hell of a large antenna. You have a listener on this side of the pond Mal. Be the first to cross the pond before Stefan does it...hi hi Mike
Mike that is very similar to the DBM mixer I built for LF using a simple and very stable Clock Osc it tunes to DC I was told that DBMs like 50 ohm terminations and I put a 3 Db term on each port,,, a
Hi Bill, Group. Just returned from a one week trip inland (Ottawa). Yes, I'm near St John's and have acquired an ITT mackay 3031A which might be satisfactory for VLF RX. Any comments on the suitabili

The Dreamers band is now becoming more a Nightmare band A simple VLF experiment to exchange reports amongst radio amateurs requires a Phd with the ability to manage a frequency stabity of 0.000000000
Dear Mal, People like to experiment, to try the impossible using all means at their disposal. Not many of us have the opportunity, or indeed the wish, to run many kWs and these days most don't have t
Thanks to Stefan and Clemens for the helpful info. Tonight the RX with the 100m wire was used to copy the Alpha sigs on 11.905 kHz at about 20 dB above the noise. The RX is noticibly less sensitive a
A good day Jim. I am being REAL Like other challenges it's a personal challenge and that fact that its been done by others is irrelevant e.g. Everest, swimming the channel, marathons, snickers.... Ha

Dear VLF, The recent discussions shows that the band is becoming alive, not just by QRO but also QRP stations, vy fine. So, there are more and more stations who can receive the signals on 8,97 kHz. W

Mike In the UK most are opposed to big signals if what you read on here is true. If I lived in the USA it would be a different story, especially way out west, some amateur radio stations in Californi
Hi Joe, from what I can find in the web it tunes down to (only) 15kHz. That's probably because below 15kHz synthesizer sideband noise would be an issue. My Sony CRF-1 tunes down to zero Hertz but you
Ah yes that NOV thing. Over here 9kc and down is free to use. Bummer for the UK guys stuck with the NOV thing. Mike WE0H Mal wrote: Mike In the UK most are opposed to big signals if what you read on

Hi Bob, For sure those Mini Circuits mixers are good. I am laying out a circuit board right now for a transverter that uses one of those. It's the G3XBM 500kc Transverter that Roger designed. http://
Put this in front of the receiver and it'll work to DC. http://sites.google.com/site/g3xbmqrp/Home/saq I think that would be an easy receive converter for someone to build. That way a guy could use h
