Sadly Marcin there is probably no answer to your question. Over the early years of LF activity I tried to make sense of the various "recipes" that were floating around. I found that in general they d
As to getting good contact between the rod and the ground is important..... mild steel rusting is likely to give poor and non-linear contact. Copper-clad steel is probably the best bet for hammering
Hi JB, yes I think I remember that....do you have any measurements of the improvement? I guess "used" cat litter is even better :-)) Alan G3NYK I've used bentonite clay (cat litter) around my ground
Hi John, interesting.....thanks for the plug :-)) Good nights rarely occur when Dst is lower but are not guaranteed when it is at or higher than -20nT. I still haven't got a grip on that on the level
Hi Markus I am wondering whether the WSPR or Opera results could help me understand some underlying variations in propagation that I dont seem to be able to pin down. Stefan reports two nights with s
Thank you John......those details tend to confirm the comment I made to Graham. the results from different receivers are dependent on their location. This is ratherwhy I suggested that one receiving
Hi Jay thanks for that observation. That iswhat I had believed but wanted to be certain. There is obviously a "coast effect" at Dave's, probably similat to Joe VO1NA, though he is closer to Europe to
Chris, It should not be necessary. The E-field probe couples to the incomming wavefront capacitively and extra wire adds little to this. The secret is the "size" of the segment of wavefront you inter
Hi John Kp=7 now and Dst -150nT but it may take a little while to diffuse South so the more southerly stations may make it tonight, just. Then further North there will be auroral noise and it has wip
can i work out the antenna current from this? Not really this is the current in the coax. If the current and voltage are not in phase then by definition you have reactance in the coax termination. Yo
Hi Chris well it may depend where abouts in its rotation the movable coil is. If you think of tuning a coil with a ferrite slug you can get a peak when the core is in the middle of the coil. However
Hi Chris Im glad the tap idea helped. It is quite difficult at a distance to think of things that might cause the effects but it looks like we nailed one. Your suggestion of RF getting into the syste
Hi Mike it is interesting to see that your "Good Conditions" were just before a bout of geomagnetic activity :-)) The Dst was nothing special last night (-40nT) but it plunged to -80nT around noon to
Hi Laurence yes I can imagine...... the impact was at around 0800z The bottom of the Dst was around 1500z. NOAA SEC shows the aurora right down to the Alaskan coast. Alan -- Original Message -- From:
Hi Joe I have not the faintest idea ! We have no access to the blacksheep server so it just does its own thing. However you must remember this s/w is many years old it was up dated about 6 years ago
I stopped myself from saying "a Wolf in Blacksheep clothing".... whoopsI just did! :-)) Alan G3NYK -- Original Message -- From: "Mike Dennison" <[email protected]> To: <rsgb_lf_group@blacksh
Ok Joe I am not totally sure that is the reason but we have seen problems occasionally with HTML. It is certainly worth a try. Alan G3NYK -- Original Message -- From: [email protected] Joe To: rsgb_lf_gro
Whilst as Mike says these ferrite RF-current meters are easy to make, a local friend of mine sells a kit which was originally intended for HF aerials but after a prod from couple of us was tested and
