Great work, Stefan. I again tried to see something from as far as Italy (and from a very noisy environment). So, no real hopes but nevertheless lot of fun and interest in your experiment :-) Unfortun
Hello Stefan, Thank you for your reply. Yes I think you are right. So probably I will let time take the decision :-) As long as the CRT survives, I will stay with it (at least I know I can switch it
Hello VLF, results of what Pauls calls an "effective sferic blanking" look really interesting. Where could it be be possible to learn more about this kind of noise blanking and its implementation? Fo
Hi LF/VLF, I have just read that yesterday resulted to be another "spotless sun" day in 2010 (surprisingly quiet for scientist). May be this fact played a role in the reduction of QRN at low frequenc
Hi LF, VLF, currently I have a CRT monitor which of course is a bit cumbersome compared with a slim LCD one. On the other hand, I have done a very simple RF noise test with an LCD TV/monitor I had in

Hello Stefan, VLF, in your knowledge, are Michael's settings for clipper/blanker valid regardless of the rx signal level or they need adjustment for farther stations? Best regards Daniele From: Stefa
Hi VLF, personally, I have had a pretty good reception from here (JN53EM) on first 8970Hz transmission (attached). On 6470Hz, I captured just a faint trace (to be confirmed it was Stefan's actually),
Hello VLF, attached is the best rx I could do at 6470Hz. May be the faint trace in the box is Stefan's. Much worse than 8970Hz at my QTH (JN53EM, very noisy suburban area). I have also recorded about
Hello Stefan, Michel, VLF, I also noticed yesterday that the signal trace on Renato's grabber in Cumiana was clear but looked weaker than captures from more northern (sometimes farther) stations. One
Hello Stefan, VLF, frankly speaking, it is still unbelievable to me that I was able to catch a faint trace of your signal and see it appearing on my PC. This is because of the intense hum at my locat

OK, I will adjust both the spectrum scale and the B slider so that even -120dB are visible on the waterfall. The C slider will be kept untouched. I will record 10 seconds this evening. Also I think I
Hi Stefan, Do you mean I can adjust the Brightness control too? Or simply select a different palette? I'm testing the .usr and it results almost in a blank screen (apart from lower frequencies) becau
