Sorry, I forgot to attach the broadband capture I mentioned in my message below. Regards D. From: Daniele Tincani <[email protected]> To: [email protected] Sent: Sun, February 6, 20
Plase see the attached capture. It was local for sure (did not appear in any grabber, including Cumiana). That said, any idea about what could have caused it? Regards Daniele Attachment: SLcapt.jpg D
Hello Markus, yes first I had a look at Stefan's grabber and at Renato's grabber for confirmation. Cumiana it is probably not working at present. About the signal I'm seeing here, I'm convinced that
Hi VLF, I don't know if this info is relevant, anyway I noticed a single mast (probably) near 30°58'19.34"N, 34°54'38.07"E on Google Earth. There are many interesting (may be) structures in the area,

Hello LF/VLF, please be so kind to allow me to post just a picture I took yesterday morning during my first VLF /p rx test :-) It shows hills behind Livorno, Italy. The exposure is very bad, just ima
Hello LF, I would like to improve a bit my home-made pre-selector for LF/MF. I would appreciate very basic advice on "mechanical" aspects like the following: the pre-selector has some molded inductor
Hi VLF, please let me share with you my hope of having found finally a pretty good place for /p VLF monitoring :-) Altough easily reachable by car, it is secluded enough that I think I could even lea
Hello VLF, is any of sub-9KHz stations planning tx experiments for this evening (around say 18.00-19.00UTC) that could be detected in Italy? Many thanks in advance for replies. Regards D.
Hello Chris, I have no doubt that that 11.7Hz-spaced lines on my SpecLab screen have a local origin. I am just curious about their source. Following web page http://g3zjo-radio.blog.co.uk/ mentions 1
I see a constant trace at 82Hz, but it appears to be 7 x 11.7Hz, as I see other similar traces at 6 x 11.7Hz (70.28Hz) and 8 x 11.7Hz (93.72Hz), etc. Does anyone know about a possible origin of these
Hi Eddie, I didn't realize you are the author of the web page that I mentioned in my message below :-) My compliments also for the very nice grabber page. Regards D. From: qrss <[email protected]> To
Hello VLF, could some of you be so kind to re-send the two Eddie's JPEG's that I forgot to save? Many thanks :-) Daniele From: qrss <[email protected]> To: [email protected] Sent: Thu, May
I have found that a PWM Fan Controller (like the ADM1031 from Analog Devices) can use 11.7 Hz as the PWM frequency driving the fan. I suspect that in my case the 11.7 Hz signal come from inside my PC
That's just fantastic! Now to solve my problem with 11.7 and harmonics I only need to choose between morphine and a clean-shaven nose (or both). 73 D. From: qrss <[email protected]> To: rsgb_lf_group
Hello Stefan, as far as I know, you should avoid loading a resonant loop too much so I would say that a preamp with an high input impedance is better (so no 50 ohms load at the transformer output in
Stefan, in fact I tried to compare a small and simple-to-build active loop for VLF reception (ref. http://www.vlf.it/easyloop/_easyloop.htm) with a short E-probe based on your design and with another
