Andrey, Ko, Henny! Thank you all for the reports. I modified my antenna and this was the first time I was transmitting with more power. 73 es gl Gerhard Am Samstag, den 11.09.2010, 23:20 +0200 schrie
Hello Group! Has anybody an explanation for the kind of signals displayed on my grabber sometimes? They appear not periodically but rather random but always around 137720. I noticed them first a few
Dear Jim ! Thank you for the tip. I really have no idea where it could come from but a motor is a possible source. Until now, I just have seen this signals during the day but that could have to do wi

Hello Marco ! I'm currently also playing around with a MiniWhip and had exactly the same concerns. It's not the original design because the 2N5109 wasn't available and so I used a 2SC24?? (don't reme
Hello Group, Stefan ! Sorry for the delay but here is a picture of the signal I received from DK7FC in JN88hl during his last VLF experiment last Saturday (QRB abt. 600km) I decided to attend to the
Dear group! Today I swapped the RX of my grabber to SDR and the antenna to a PA0RDT-design. I also did some minor changes to my grabber-page. So everything is new and regarding to the tests I did, th
Hello Stefan! Good news! I will be listening tomorrow. I also have set up a grabber page at members.aon.at/grabber/VLF but I'm not sure how well it will work. Because signals in the dreamers band are
Hello Roger! I'd like to participate in your experiment but with 20µW of ERP, I have no hope to receive your signal in JN88hl. Pls QRO. 73 es gl OE3GHB Gerhard Am Freitag, den 01.10.2010, 20:58 +0100
Hello Markus ! Do you think Stefan will transmit again or is the experiment over? Do you have any infos on this? 73 es tnx OE3GHB Gerhard Am Samstag, den 02.10.2010, 15:44 +0200 schrieb Markus Vester
Hi Stefan ! I have sent a report with a screenshot to your personal address. Have you got it? Nearly 20db over noise at QRB 631. 73 OE3GHB Gerhard Am Montag, den 04.10.2010, 23:48 +0200 schrieb Stefa
Dear all! Has anyone tried to lock SpecLab to a 1pps Signal yet? The 1pps Signal is mentioned in the manual as a possible source for calibration (as long as it has "low" jitter). In my job, I also ha

Hello group, dear Stefan! You are right, I am using a PA0RDT-like antenna. The differences are: Instead of the original 2nd transistor, I used a 2SC..something. A RF, low noise, low power (200mW) typ
Hello James ! I had a similar problem with an old Toshiba Satellite notebook. I solved it by setting the cooling method to "Quiet" instead of "Performance" in the BIOS and adding an external fan (120
Hello Stefan ! You're right! Those effects have been observed before. Ossi and I have watched different closely spaced grabbers (like mine and DF6NM) and found very similar results. One explanation f
