I have a Wandel-Goltermann SPM-19 I would like to dedicate to the Spec Lab plotting duties. This unit has had a receive problem every since I got it over ten years ago. So I have primarily used it as
I am now plotting DCF39's signal as received here in North Carolina. The plots are uploaded at ten minuets intervals. The latest plot can be accessed from my main web page at: http://www.w4dex.com/ O
Looks like my best capture of Laurie's and Jim's signal occurred around 0630. Comparing John's captures with mine it's obvious it takes a little better conditions or a little more power to get anothe
I'm up and running on 135 kHz as of 23:00 hrs. Screen captures will be posted at the usual location: http://www.w4dex.com/argo/135khz.jpg Will leave system running overnight in auto mode. Dex Dear Jo
Noise here in NC is about as low as it gets. It isn't often I can run Argo in manual gain mode. This probably won't last long after dark. Screen captures will be available at: http://www.w4dex.com/ar
Push hard, I'm looking. Posting to: http://www.w4dex.com/argo/135khz.jpg Dex a quick look at Steve's site shows that the DCF39 level is -12dB relative level at 2230. I will put out a test transmissio
On several occasions the HBG plot showed an almost instant drop and return of the signal received here in NC. These drops didn't look like propagation events so I emailed the HBG engineer to see if p
I believe the jet stream is in your favor Alberto. Thanks for posting that shot. Nice to see what we are looking for. Dex If our friends over the pond are curious to see how the T/A slot of spectrum
My Argo window for tonight's run can be seen at: http://www.w4dex.com/argo/135khz.jpg Noise level is low right now. Just hearing an occasional static crash. Dex Captures 0f 136.922 from W1TAG will be
No copy in NC last night. Propagation looked fair but S/N was poor. Lots of QRN form somewhere. QRN wasn't local so LF propagation to it's source was also good. Dex
There was a sudden 15 dB drop in the 75 kHz HBG signal received here in NC at just before 0600 UT. Looks like it was down for about half and hour then suddenly came back up to normal. The noise floor
Looks like a few signals starting to come thorough even with DCF39 20 dB down from it's peak and with a Kp of 4. http://www.w4dex.com/argo/137khz.jpg W4DEX
Laurie, I'll do uploads every 5 minuets at: http://www.w4dex.com/argo/137khz.jpg Watching 137.772 to .775 kHz Dexter Cndx looking fairly good, Kp down to 2, so I will transmit from 0500 on137,774.4kH
W4DEX currently seems to be swamped by noise. You are correct about the noise Markus. The 4.5 blank space in the plot is where I disconnected the antenna while a line of thunderstorms passed. We had
The static crashes are chopping things up a bit, but CT1DRP is presently visible here at 0010 on 137773.6. DCF39 can't even get above the QRN here. Turn up the wick Brian! W4DEX
Brian's signal was solid here in NC for about 9 hours straight. The overnight captures can be seen in a directory at: http://www.w4dex.com/argo/20feb03/ G3LDO had a good signal but the 3 is missing a
