Thanks Martin for your comment. I will make a pre-amp and check, what equalization is neccessary to keep the Kiwi-rx well below clip-level. By the way: What happened to the FFT noise plots on the Grafana-website? Since this morning, they do not app…

Made some changes to the calibration adjustment parameter DEFAULT in conf.file.... There was a mistake in the formula of the spreadsheet. So the cable losses of the longwires were not included. I need up to 200m cables - so although on low frequenci…
-
Rob, I will setup the 2x1m measurement active dipole soon - the efficiency should be close to the value LZ1AQ calculated (about 2db/m from 350kHz to 30Mhz within 3db). Then I will compare my much longer 2x3m dipole with the smaller one on exact the …

Yesterday afternoon, I placed my Northwest antenna new - it was broken earlier. As I already had a 170m Beverage to the east (South Asia, Western Australia) in place, I wanted to have something similar to Northwest also. The Northwest antenna is a l…

Hi, Rob - thanks for the hint. I checked my configuration of Maidenhead locator. I noticed that I configured 'jo10os' (all small letters) and changed it in JO10os (two first letters in cap-letters) - so far, I did not get error message again in the …

many thanks for setting this up, Gwyn - great tool! However I have done nothing to get my data in this database... I would like to thank the person who forwards my data to this database (great service...hi) ... the only what I did, is post the noise…

Rob, some problem shows up regularly - it shows up in the wsprdaemon.log file I do not understand what the code means, but at least I understand it is an error. Do you know, what the problem is and what I need to do ? Currently I do not use Suris…

ok Rob, understood. Back to noise graphs: Is there a possibility (parameter in .conf file), so that noise graphs are only uploaded for specific bands, not all bands the kiwi configuration is set-up for, to listen. So for example: Kiwi listens to ws…
-
Rob - to justify: It is not THAT bad...hi During your morning time I listened again on topband ( during 160m contest) and compared your antennas: Marconi vertical, TCI 530 and also the 8078 port to boost 15Mhz and up a bit... All antennas have about…
-
Hi Rob, I checked again the signal levels of KPH TCI530 antenna at about 8h...8h30 utc in comparison with other TCI 530 from a different location, but close enough so you may compare. I think just south of San Fransisco, west of San Jose, there is a…

P.S.: "I can hear lots of westcoast stations in CW and WSPR spots also...." = I mean, I can hear these stations on my radio in Belgium with my little vertical dipole !!
-
Hi Rob, thanks for detailed information - very clear. Are KPH_HF_77 or KPH_HF_78 really the same receiver streams as on kphsdr.com:8077 and kphsdr.com:8088 ? I connected today at about 17h30 utc, your local morning at 9h30 local time - so well loc…

I just saw the Grafana chart for the first time, Gwyn mentioned above. I am sorry for my all but really calibrated noise charts! Being back after some 'pause', due to health problems, I need to start things up again - therefore I was experimenting a…
-
Many thanks James, I did that and it worked... Interesting new features, I learned. So now it needs some time to find out best antennas and locations...hi Ulli, ON5KQ
-
Many thanks for the information - so I really need to change my settings for the two receivers in the .conf-file To WA2ZKD: Please forgive me not to understand coding in Linux.. What do I need to do, if I want to use your methode by comparing perfo…

Good afternoon, after some time, I am again a happy user of WD installed on my VMware Workstation Player 15 (Virtual machine with Ubuntu 18 LTS). The updates posted on Github can be easily installed on a regualar basis by "git pull"... I …
-
Rob, hopefully you can realize the receivers at kph as planned. In the past the marconi T was not usable much, due unlinearities in the feedsystem, I think. I can imagine how much efford it needs to build something new at a remote location with limi…
-
Rob, thanks for info on that... I need to reinstall everything, as I cannot input this now, because the VM doesn't start Linux anymore. May be it is best to buy a rasberry pi mini-computer and run it native. Which mini-PC, I should buy to run 2 Kiw…

Glenn, "So "How come everybody thinks noise is worse these days?" is a good question." Look at the noise between 3.75 and 5.3Mhz here on5kq.ddns.net:8074 This noise comes from the local telecom operator and is the modems return p…

I had WD 2.5a running on VMware Workstation 15 player Installed Ubuntu 18.04LTS with all additional software necessary. WD runs flawless for some days. However suddenly i realized, that some bands do not spot from one of the two kiwis anymore. I fo…
-
The noise graphs for me are only a kind of indicator, when using different antennas with WD: - the feedsystem losses are more or less known, as you can measure them - The antenna to my best possibilities is modelled with NEC2. We can use the results…
-
Just to clarify: The LTspice calculation for the 2x1m dipole antenna factor was with the pre-amp included ! According to Chavdar he designed it in a way that the antenna factor is nearly constant - at least that is, what I understand from the specif…
-
Hi - to have some better idea of what the correction values must be in my situation with my antennas I plan the following: - build a reference vertical dipole of 2x1m long on a 3m fiber pole (so lowest point of dipole is 1m off ground) The dipole wi…
-
I can't believe it: Just after I sent my last post - the spots appear! 40min delay on wsprnet.org !!! not seconds - almost one hour delay!! Problem seems to be solved, but not realized in real-time...hi Ulli, ON5KQ P.s.: sorry for the noise here.…
-
Stu, I wrote my own index-file to link to the noise_graph.png... renamed the original Apache index file This works - tested with browser : the correct noise_graph.png is shown... Now the only fundamentel problem is : NO spots ! (waited more than 10…
-
Worked the whole evening, with a fresh installation of everything. new VMware Virtual machine, new Ubuntu, all details of WD, which needed to be installed.... Finally: everything works - can see the noise reports also and massive number of spots....…
-
Martin - the system here is totally reset - VMware machine destroyed - I am in the process to build everything new... Old noise files are in http://graphs.wsprdaemon.org/ON5KQ/ I have the system partly reinstalled, but no noise graphs are working y…
-
I think the whole file-system crashed on the VM-ware machine... I will make a complete new install, as I get errors now with files missing and files are written into the wrong folders etc... finish for today Ulli - ON5KQ
-
By the way - I deleted everything with DEFAULT and after in the lines... = no change So the function is disabled anyway - why? Ulli, ON5KQ
-
Martin, If I change the line, so I do NOT have any extra spaces, it doesn't change anything... whatever I input behind the DEFAULT in the line, it don't change the noise graphs.... I don't understand it? That's why I copy and paste the lines here...…
