This was sent to the LF reflector but didn't seem to get there Give it another go have Three or four years ago, at an LF convention at Windsor, this aspect of saving material from the LF reflector wa
coil to the insulator. I found that the nylon cord had burned through. I switched off the transmitter and replace the coil with a length of copper wire to support the insulator. Should read "replaced
I had a similar experience to Mike this afternoon. While running the 72kHz transmission I noticed that the support insulator support cord near the loading coil had parted and the antenna was held onl
I hope to be on 71.6+kHz around 1600 UTC (30th Oct) late this afternoon for an hour sending normal CW and QRSS. I have repaired the faulty module but will still only be firing on two (about 600w) unt
I have in the past found power MOSFETs can partially fail, where they appear to be working when simple go/no-go tests are applied, but quickly get hot and fail when put back in the circuit. so it is
I hope to be on 71.6+kHz around 1700 UTC tonight for for an hour or so after I have added more mH to the coil to get it to resonate at the bottom of the band. The antenna was folded over during the s
I have a faulty Decca PA module and I suspect that one or more of the IRF250s have blown. While faulty FETs in the old BK amplifiers were easy to locate because when they failed they developed a shor
I hope to be on 71.6+kHz around 1800 local tonight for about an hour I did manage to get on 72kHz around 1820 with two modules of the Decca Tx firing. Unable to get the antenna resonance down below 7
Hi Mike Will be on 71.735kHz QRSS at various times today and Sunday (if the antenna is still up). E-mail me if you want an inband or crossband sked. I hope to be on 71.6+kHz around 1800 local tonight
Hello LFers, I am QRV on 136 again after several months using the fold-over mast for other non LF experimental projects. I have a new loading coil made up from a Decca loading coil and made a outside
Hi Arnie Still working hard to get approved the use of the 136 kHz band here. So far it seems that we will get it soon !!! Thats good news We don't have access to high power MOSFETS as you may imagin
Hi Ian Thanks to all those who replied to my posting. Will be on 71.75 QRSS3 ot 0900z tomorrow, Saturday for a sked with Laurie. Other reports (even negative), or QSOs more than welcome. Also will be
Hi Dex I'm working on building a dedicated system for monitoring LF signals. For a test I am presently recording HBG 75 KHz and posting to a web page which updates every 15 minuets. Time on the Spect

Laurie said: Although there was rather poor copy of signals from G3AQC and G3LDO (thanks Peter for joining in ), last nights experiment was really quite successful. At the time when signals were seen
Laurie said At the moment the Kp index is down to 1 so this should be ideal for a T/A crossing. I will be on tonight from about 23:00UTC Freq 72.401 QRSS120 Hope some of you will be able to watch,and
Hi John, Not seeing anything from you at this point. I thought there was a signal earlier, but it was well before 0015. Am getting some pieces from Laurie. OK I will be shutting down at end of this t
Is anyone else transmitting on 72400.28? John Andrews, W1TAG I started transmission on 72.4003 at 0015UTC. I notice that the frequency has drifted to 7240032. I had left the door of the transmitting
Gee, Mal, if all of us follow this general statement of yours, you will have few new stations to contact (as you were complaining about only a month ago). All debates aside, at least the loop allows
Fine! I personally don't mind as I find them interesting - the question is do the majority of the reflector users mind the scope of the reflector to broaden to include such technical intrigues? I mu
