I have a very noisy EM Environment. Optimizing takes time. My environment is variable.
Thursday I think it was I had a completely new interferer which kept me reduced or in interferece most of the day, on all three systems 689, 791, 1439. Near Field Magnetic and Electrical. Never did chase it down... then it vanished sometime overnight. We have to live with such situations, and adapt and optimize as best we can.
Shielding ferrites of no use for magnetic interference. Some effect for electrical. Watching your signals for a bit, I suggest shielding would be a waste of time for you.
I have 3 different types of E probes. It is not so much the 'size' of the probe, it's the height above earth, and isolation from structures, trees, etc. The 'surface area' (size) is important, but 'bigger' isn't necessarily 'better'. The assembly is EXTREMELY sensitive to charge state, and in fact operates with a LOSS as far as 'power' into the Controller amps. The E field assembly, including the Coax, is NOT an antenna.. It mirrors the electric charge state of the Earth / Atmoshere 'capacitor'.
See
https://forum.blitzortung.org/showthread.php?tid=2749 for a quick look at 'propagation / detection".
my three stations, respectively, (in mm) 350*2 - 150*3 - and 250*4 ---but all are 21 feet above earth, no significant difference in performance, though the gain settings vary for the E channels.
For H field, I Use a modified Ferrite build, 300*7.5 core, finding these the very best size and option for many reasons, in my situation. Here's a link to the V1 version. 50mb PDF:
https://sferics.us/misc/CSS%20Thingie%201b.pdf I currently use a Version 2, which I won't describe presently.
This project is not about 'competition' to be on top of list, though that is a great ego kick,.. it's not about 'detecting' strokes. It's about LOCATING strokes accurately, and for that goal, generally only about 17 stations within the region will actually be used... the BEST data channel from those. Everybody else's Involved Data classes them as 'detector's.... You are computed on Region 3 Server (Amerucas) so your data within region selection should be 'North America) though Canada 'sort' is possible.
I'm workwing on a page which shows how your signals are computed. It's still very much draft. but it may help.
https://sferics.us/resource/SignalEval.htmlYou're running 'automatic' mode. This will drive your gains up and down. Suggest full manual, no automatics at all.
You'll chase your own tail trying to optimize in automatic.
You're apparently using stock 200mm ferrites. You need to add on your configuration data on BT the diameter, which I think is 8mm.
On that same page,a the antenna config should be HA=0, HB=1 HC=2 (undefined if not used), E ALWAYS on 3, 4-5 undefined for sys BLUE
Set all Thresholds (triggers) at 100mv and apply/save.
Set all gains at 10*10 HP ON.
Disable H Channel C, since your'e Not using it.
Gain settings affect the Analog Chain.
Threshold is a digital function. 100mv is the 'sdtandard' base which 'Effective Gains' are computed. Try to leave this at 100.
