Hi Ian That experiment confirms that WHATEVER configuration of other earths is used, the system prefers to have the coil earthed back along the screen of the coax and then by any tortuous route you c
Hi Laurence bb) To confirm Ill be active from Accra Ghana from around 16th-24th June 2003 on 136Khz receive, part time. Im hoping to have email reflector access but cant guarantee at this moment. No
Jim & LFers Getting back to the topic of LF antennas, another useful type of feed method for LF antennas is the "450ohm unbalanced air line", or, to the layman, the "bit of wire hanging in the air".
Hi Hugh Has anyone else tried this with their LF/VLF receivers ? I have put a microphone on my SLM and have been receiving bats. I used a tiny electret condenser mic capsule on the input of the D2006
The choice is not entirely arbitrary - as I recall, 50ohm coax gives the best power handling capability for a given size of cable, while 75ohm gives the lowest loss. This is probably academic in amat
HI Jim. This looks like a nice tuning aid and judging by your signal it must be working, the only other signal from the South that moves my S meter is G3YXM, the others could certainly benefit from
When I put up the antenna and switched on the 73kHz station at around 1730 local I later heard/saw Jim BMU but his signal was down. The band seemed quiet and as I tuned across the band there was a ch
Hi Ian Been copying Peter and calling him between last posting and this without success, and even Jim is down to M - and that is stretching it a bit. Weather rotten but that means antenna current is
I hereby promise faithfully that I will call CQ on the quarter and three-quarter hours from 1800z on. Freq. 72KHz +/- I have just monitored Jim MBU working Ian again. Nothing seen of Ian. I can see
I have just retuned my 60KHz antenna slightly and am trying to listen for Andy's beacon on 71.9KHz 10s currently without success. Transmitting on and off QRSS3 on 71.95 Regards, Peter, G3LDO
Hi Ian and 73ers I thought I saw something after Jim this AM but we have a bit of a family upset and had to quit the shack rather sharpish. Also had GI0GDP over to assist in making field strength mea
Received this via G4FKK "QRM and QRN levels are low in Ghana at the moment and I'm receiving a constant signal from DCS39 at good visible levels (abt -61dB), with a 1.5Hz Doppler shift. I'm monitorin
Back again after a short period in hospital. My first serious encounter with our National Health Service, which in my opinion now, is much maligned. Nearly 90 e-mails waiting to be read, nearly half
Your signals received at G3LDO on the morning of 12 July over a period 0040 to 0034UTC. Correction 0040 to 0134UTC Its that negative time stuff again! Regards, Peter, G3LDO
Hi Joe Will be on again tonight (tomorrow morning 0000 UTC). Your signals received at G3LDO on the morning of 12 July over a period 0040 to 0034UTC. My Argo settings set incorrectly at 10sec instead
Bryan Is 24in wide 24 ft. long [inside the ridge of my roof } of aluminium foil tacked to the rafters not better as a top capacity than 100ft of top-wire down the garden ?. Don't even think about it
Bryan Of the earth return loss resistance, how much of the resistance is the actual earth rod(s)-to-soil contact and how much is the earth path ? With an inverted L antenna , is not a counterpoise of
John, W1TAG said: -- It is occasionally useful to suggest to the newer readers of this reflector that despite the advice given by G3KEV, significant fun and useful knowledge may be had by LF experime
Had a good last evening on 73, QRN was pretty bad. Spent some time looking for MI0AYZ, sorry we did'nt make it Ian. Saw Peters QSO and captured part of Ians transmission,see attachment Finally had s
