The first Schumann resonance is not at (300000/40000)=7.5 Hz, but higher, usually around 7.7-7.8 Hz. I was astounded when I observed it for the first time about 12 years ago and found that the freque
Hi Victor Your findings agree with mine, the Schumann fundamental resonance is high and does not agree with published data. My reason for not displaying the Spectogram, just my tracking Plot of SR1,2
Hi Eddie, two possibilities,the data are not correct,or we are seeing something else... 73 Victor --Oorspronkelijk bericht-- Van: [email protected] [mailto:owner-rsgb_lf_group@blacks
Hi Scott, I am using a E-probe 100X1cm,4 m above the roof.Amplifier is a cascode with a fet 2N4393 and a transistor BC550c at 10 ma,output stage a BD139 emitterfollower at 100mA/28V. Gate seriesresis
I raise my head for the chopping block again. Among the urban noise and carriers, due to low QRN today, this is what I have seen before and is conducive with the Second Schumann Resonance (red marker
Hi Victor / Eddie What are you guys using as your antenna for this? Thanks, Scott Your findings agree with mine, the Schumann fundamental resonance is high and does not agree with published data. My
Hi Victor Agreed. It is said that the SR is higher, I searched for data and examples. IK1QFK is off air still, exact frequencies are difficult to see from his capture, I can see that SR2 shows strong
Hello Marco Thank you for your input, yes I was astounded to see them then confused by the frequency differences. Maybe some captures on the web have been calibrated to put the theoretical frequency
HI lf, not amateurradio but very interesting,zevs and the Schumannresonances.No sign of the 60Hz powergrid,yet.. 73 Victor Attachment: schumann.jpg Description: JPEG image Attachment: zevs.jpg Descri
Hello Marco, thanks for your very plausible explination.I don't have a very quit location(city of Utrecht),so very pleased to receive anything at all. As doctor Spock would say: "facinating" 73 Victo
Hi Scott I am using my 9kHz DJ7FC E Probe un modified, optimised for 9kHz, it was a long shot but I took a look for ZEVS and there it was. 73 Eddie G3ZJO What are you guys using as your antenna for t
Hi Victor Undefined boundaries to the frequency bands, correct frequency regions, it looks convincing to me. What antenna and RX are you using now. 73 Eddie G3ZJO On 12/07/2011 08:17, victor13@online
