It could be that more have been used than we know about. I had an e mail this week from G3XZX who has been conducting low power 73 KHz tests over distances of only a few kilometres. Maybe there are
But be aware the in contradiction to the above the core material is far more critical for use in low pass filters or any other resonant circuits. There the 'red' Amidon cores can be used. Or use air
Jim Many congrats on your report from USA. While you were beaconing last evening I noticed a strange phenomenon on your signal which I can best describe as being similar to the aircraft flutter heard
Welcome and congratulations to Alan G3XZX in Exmouth. Alan and I completed a QSO on 136 KHz this morning followed by a cross-band to 71.8 KHz, where Alan's 12 watt signal was a perfect copy 559 despi
Hello John I applied about the same time and it came through in a couple of weeks. 73, Tom G3OLB Hi Bill and Colin, Congrats on getting going on 73kHz. Can you tell me how long you waited for your NO
Come to Devon with a big reel of wire under one arm and your 600W PA under the other! (Mine has RIP inscribed on it). I once used a 132ft loaded cliff on 160m by throwing the wire off the side of Ber
G3KEV Just to show that you are NOT a sad old twit with a very large chip on your shoulder, why don't you offer your unreserved congratulations to those who, unlike yourself, have the operating skill
Martin Start, as I did, with an old long wave ferrite rod antenna in series with your wire. Sliding the ferrite in and out of the coil will resonate it. Not much good for transmitting but easier than
Hello Martin and thanks for the report! Loran is very evident here in Devon on my TS-850 'barefoot' (no preamp). There are some quite strong signals from ON,PA0,and DL which you should be hearing on
Yes, that's a thought because I think Laurie was testing as well last night and he is about the same strength as Jim with me. A very low frequency heterodyne.
Dave I was also eavesdropping on Ron & Christer's QSO while working in the shack and Christer was no stronger than usual here in the South-West. However....I worked him one night a few months ago and

Andy and co. I intend to be there. Talk in for mobiles on 136? 73, Tom G3OLB Although the planned forum still several weeks off, it would be helpful to get an idea of how many people are going to be
Thanks Alan for the direct e-mails. I use a driver transformer wound on a chunky ferrite tube with 5 wire ribbon cable, one primary and 4 secondaries, instead of the H bridge driver chip. Seems to wo
Alan What a convenient piece of timing! I was intending to play with an absorbtive load at the third harmonic on my Tx this weekend, so your diplexer design arrived at the right time. I gave up on th
