Hello Paul, Also congrats to the QRSS3 5km distance! :-) Who is the next station that can receive your signal? 1nF / 345mH sounds very good! 1250 Ohm, is that the overall (loss) resistance? If not, h
________________________________ Von: [email protected] im Auftrag von James Moritz without filter. Basically, at this scale, everything around 9kHz and below is QRM... Tnx for that
Wow, Michael, thats really just a small dot but with excellent SNR! Next time i will give 6dB even more. I will reach this 1A antenna current! Just to note here, that i can see later how long it took
Dear LF group, Thank you very much for your participation on my todays experiment!! Congrats to all receiving stations! Very well done since my signal was rather weak today:-) There are coming up mor
Aah sorry, this is the link to the distributor for those old TV transformers (sadly witout a picture): http://www.oppermann-electronic.de/html/teslatechnik.html (part number: Tesla 82) 73, Stefan <<w
Hello Daniele, VLF, Thanks to all for trying to receive something! Daniele, your picture shows the typical QRN situation in the summer. The minimum is early in the morning and QRN comes up at arround
Dear LF/VLF, Currently, there are many lightnings in germany. Here near Frankfurt it is overcast, still dry and no thunder to hear but the clouds look dangerous. Thus i will do no VLF TX tests this w
Interesting! So, here you could even check the (positive) influence of all the conductors that could supply the conduction. Who is the RX stn in 3km distance? Has he also tried to transmit a signal a
Thank you Henny and Victor and all others for the reply! I hope the WX will not disappoint us ;-) ________________________________ Von: [email protected] im Auftrag von victor13@onli
Dear VLF, In germany there is a distributor that offers such a TV transformer, of course without the HV cascade, so with an AC output. I have ordered such one (not this one of my picture i sent). The
Mal, That's fine! So you could use 1mm diameter enamelled wire for minimal losses. Also the HV will be rather smaller. Sounds promising... 73, GL Stefan/DK7FC ________________________________ Von: ow
OK Roger, very nice! If you would go to use a PC instead your ears, you could immediately get some "gain" of say 30 dB and thus much more distance. I also like and normally prefer CW instead of ear r
Hello Michael, At least in the autumn/winther, we will successfully get a contact i assume :-) Thank you for beeing QRV! 73, Stefan/DK7FC ________________________________ Von: owner-rsgb_lf_group@bla
Hello Roger, Tnx for infos, vy nice! You have plenty of space for good ground electrode antennas. :-) And you are well experienced with web applications ;-) So SpectrumLab will be no problem for you
Hallo Michael, Danke für den Empfangsbericht. Du bist etwa doppelt so weit von meinem /p QTH entfernt als mein Grabber. Daher hat mich das S/N schon interessiert! Kannst du mir mal ein Bild von der A
Hi Horst, I remember the times in Februar (or was it Januar?) where you gave us that little information about your test on VLF that caused all the following things ;-) Nice to read the mails that cam
Hello Roger, For your ground electrodes, ground electrodes may be the best "antenna" in some 10...10m. I'm not sure how to calculate field strengths but i just know about the 1/d^3 dependency, so twi
Hello Horst! My last mail was written in the afternoon but was reflected just before some minutes :-/ You already have been out and got good results, very fine! I am interested in your 800m long wire
Last Question for today: Is Paul Nicholson also QRV and informed? What about the italian VLF Receiver in Caselle / Sicilia (1430km)? And SQ5BPF, also informed? Also tnx SV8GXC for beeing QRV! nw hr q
