Hi Stefan! At least at my site, QRM/QRN was pretty low this day and so rather the (too) wet soil could be the reason for your weak signal. I watched you grabber and when I saw you were "only" 40db oN
Hello Markus ! Yes, it is Ossi but he now went down for 100mHz. I just saw Stefans trace also on the 4X grabber !!!!! Could you tell him? 73 OE3GHB Gerhard Am Samstag, den 04.12.2010, 13:14 +0100 sch
Hello Horst! The cheapest way is to obtain 2 computer-power supplies from the junk-yard (= for free). Then you have to open both, disconnect the negative supply from earth-potential (but of course NO
Hello Rick, Markus! Or maybe your sound-card does not cope with the actual sampling-rate / FFT setting. I had such effects on different sound-cards, showing me signals where none is. I also tried Ste
Hi all ! I was following the whole discussion about the so called "earth-mode" and the used antennas with interest. Mal told us that he sees those antennas as "lossy dipoles" while others stated they
Hello group, Stefan ! Here are my reports of your experiment today. Was there a CW-transmission? I recorded a part of the signal on 8970 (after QRSS600 transmission) but I'm not sure if the announced
Dear Stefan, group! No, unfortunately in the moment I just can switch on/off the heating in the garage which will cause the DDS to drift, hi! But I could work with carrier on/off the next time. So 90
Mal, Rik! I'm aware, that usual ATX power supplies only deliver high current on the +12V supply, whereas the -12V supply is rated relatively low. And yes Mal, you're right: The +5V output usually del
Lubos, Stefan! I have checked my grabber-archive for yesterdays signal but couldn't see anything on my picture, see attachment. So I guess it is very weak and close to you Lubos. Unfortunately I have
Hi Mal ! Here's another Link: http://www.antennex.com/preview/archive3/powers.htm Mostly the screws of PCB provide the electrical connection between earth and negative side. Sometimes it's enough to
Dear all! I have added a EU-window to my grabber: members.aon.at/grabber because I saw increasing activity in this segment recently. I appreciate this activity down there, because this is where EU st
Hello Stefan, group! Attention the 904km on 6470/5170 were archived to Warsaw, Poland not to Breclav, Czech Republic !!!! 73 OE3GHB Gerhard Am Mittwoch, den 15.12.2010, 12:04 +0100 schrieb Stefan Sch
Also good copy of the 5170 here but on Stefan's last experiment the 5170 was better than today. (compared to today's signals on 8970,6470..) So either noise level is higher today on 5170 or something
Hello Markus, group! Indeed I was transmitting yesterday. The time is shown with the white area on my grabber as you supposed. My generator is not GPS-disciplined and so drifting downward. On the oth
Gentlemen! We are used to receive signals as slow as QRSS60 and slower.....compared to that, what are some few minutes of delay on the reflector? Right, nothing! So from my point of view, I'm complet
Using Firefox under Linux (with some filters and pop-up blockers, sitting well protected behind a router) , I haven't got any problem! And believe me, I am visiting this site for more than one year r
I think there even was a faint trace of his signal on 6470 on this 4X grabber. But it is very weak and yould be somewhat else. Am Samstag, den 04.12.2010, 13:26 +0100 schrieb Gerhard Hickl:
Dear group! In my previous post I told you that the noise is now even louder than 2 weeks ago because the antenna-current increased from 400 to more than 500mA. The more I wonder why my two cats are
Hello Mal and group! ....."a few in parallel".... My PA is using a single IRFP260N and if I want to put another one "in parallel" is it necessary to "decouple" the gates by two resistors (a few Ohms
