Worked Dave YXM after Laurie and Jim on Saturday. However I was unable to copy Dave on CW mainly due to the ECM smog. Used mixed mode CW/QRSS3 The electrical QRM situation has has become very much wo
I occasionally refurbish old communication equipment for Amberley museum. On my last visit, to return a spruced up AR88, I found Dave, the curator of the Radio and Telephone section, fishing out an o
It seems KL1X is right... there's still something wrong with the ionosphere. Aside from the LORAN lines, only 2 dahs came through on 137.7733 kHz at ~0400Z this morning. It is somrtimes a good thing
Jim M0BMU said My loading coil lives outside in a shelter made of plastic sheet over a timber frame. To get rid of condensation, I have an old fan-heater in the bottom of the housing. The 2 heating e
The frequency 137,773.0 was chosen by KL1X for looking for EU stations earlier this year. This was done after some exchange of .jpg s to find out where the Loran lines and noise bands were. Loran is
Alan Melia .. the Kp index rose to 6 again for two periods today. This is due to the high velocity solar wind stream issuing from a coronal hole. However there was also an Class X1.6 X-ray Flare at 1
(1) It would be very helpful if a pre-advertised DX station would say in advance what is the shortest dot length he will use. If Argo is set to a shorter dot length, then all that will be lost is som
On Monday I had a visit from Laurence, KL1X. He was on his way from Surrey to Exeter and by the time he got here it was dusk. I showed him the garden shed transmitter shack and fired up the transmitt
Mike What speed was this? I had a QRSS30 screen running (as well as the QRSS120) and saw what could have been UA9OC sending QRSS10 at 0.15Hz HF of nominal, at midnight. The wrong speed screen makes i
Mike, G3XDV said These are by far the strongest stations you are likely to see. I will try to add my signal to the fray, but need a timer to switch the Tx on at 0500 or so. This is important as I can
Hi John and Joe I can report similar results to Joe's. The 0600-0700 period was best, though DRP was visible in pieces overnight. Thanks for the reports. I was asked by KL1X to QSY from 137.773.4 bec
Väinö Thanks for the capture - it wasn't me This looks interesting but can not interprete exactly what has been happening - and when, the time axis (and freq) is not exactly correct. The time lag of
Hi Jim For tuning LF antennas, I have for some time been using an oscilloscope to monitor the current and voltage waveforms at the TX output. Resonance occurs when V and I are in phase, and the load
. I have had a week or so off from LF and computers to go and work as a volunteer guide and ship keeper on board the replica of the HM Bark Endeavour at Shoreham by Sea harbour. The purpose of bringi
I was working newcomer John, G3JRL, in Weymouth, who was 549. During the QSO someone whose callsign is old enough that he should know better called CQ twice over the top at S9. He then seemingly deli
Hi Ian, In the early days of 73kHz many of us were using the BK amplifier and during these experiments in trying to get maximum power into the antenna many fuses and FETs were blown. Lech Laszkiewicz
