Hi Jim, I hope you don't mind that i'd like to share the email with the reflector, because i've a thought that might be interesting. In my view, the Loomis experiment it is rather the detection of a
I haven't tried this with 300m kites, but even ordinary low-band dipoles can charge quite quickly if they are high enough, so 100uA seems to be a good approximation. This is already comparable with t
Hi Jacek, DC, Yes yes, i already see a new project for summer :-) A floating antenna will charge up to a voltage where the E field strength is high enough to start partial discharges, something like
Greetings, How about using an ancient high-voltage "ballast" triode, as used in colour TVs ? They may emit some X-rays when fed with anode voltages above 30 kV (no risk, no fun) but they are very rug

The HV triodes are a good idea (PD500?). Maybe a GPS-synchronized rotary spark gap? VY 73 Jacek / SQ5BPF Greetings, How about using an ancient high-voltage "ballast" triode, as used in colour TVs ? T
Here some interesting paper about Atmospheric Electric-Field Gradients https://pdfs.semanticscholar.org/f67f/4a4908835530a87613d9922d07e6748ff9ea.pdf Claudio IK2PII -- ZE-Light e ZE-Pro: servizi zim
A steady signal from the 136 kHz sky-current transmitter could indicate that a data bit might be available later from the 10 Hz sky-current transmitter. Agreed, the triggered gap sounds better than a
Hello Jim, Yes, indeed. I'm now preparing the circuit and want to set it up in the evening. Found an IRF820 in the 'junk box', a good choice. Or, maybe even a BS170 will work. It handles 60V only but
...the circuit is completed (attached). First i used a simple rectangular input signal coming from the source, over an ferrite core. The gate voltage was +-10V. But then, obviously due to the FETs in
Well, today: The circuit in operation on the INV-L since last night, 100% WSPR @MF. The reports on the local RX in 20m distance were between 0...+7 dB at night and -11...-9 dB in daylight. On the tre
From observation: when a charged cloud passess by, you can get about 15mm sparks from a dipole for 80m hung between two 7-story buildings. This happens more often than once per second. Say 40m horizo

Hi Markus, DC, Thanks, it is of course a good idea to make the circuit resonant. When i thought about the first circuit i also had a thought about a resonant system but came to the result that this w
