Also: I do not understand the syntax with the DEFAULT parameter.. What is wrong with this syntax: "KIWI_0 192.168.1.102:8073 ON5KQ JO10os *some password* DEFAULT:0,20:-2, 17:-5, 15:-6, 12:-8, 10:-9" &qu…

Thanks Glenn... I'm sorry, for too much noise in this forum thread... Ulli, ON5KQ

To support my experiments, I have now a 2nd kiwi on my table The Noise-plots from WD are as follows: - Kiwi_0 has a 3m monopole (GP with 20 short radials), LZ1AQ pre-amp in dipole mode. I have adjusted the Noise-plot taking some net-gain (including …
-
Glenn, it is clear, that loss with a given very short radiator will increase dramatically away from the matched situation of the resonant radiator. However in practice towards lower frequencies the noise levels increase also dramatically - what we n…

Hi Glenn, Taking S-parameters and using QUCS is exactly what I was planning to do... However wx outside is that terrible, that I better read a good book inside, rather than open the door and work in de mud of the fields...hi So - just wait a while,…

Glenn, I have now a thin piece of wire (approx. AWG 18) - 6.3m long attached to an old fishingpole - this is my vertical radiator. There are some 20 radials about just 5-6m long. I am feeding this directly with a high impedance pre-amplifier (in fac…

The WD-Kiwi is now running without any Default parameter in the conf. file. But note I am using an active vertical. I adjusted the total antenna plus amplifier signal level as such, that the strongest stations with good propagation just NOT overdriv…
-
Many thanks for all the answers. I deleted the old noise folders now, because obviously they do not show the correct levels, as I didn't understand the Default terminology correctly. Now to begin again, I just don't set any Default parameter - let's…

Hi Gwyn, I read your paper about the Noise measurements from researchgate with great interest... excellent writing! I am sorry, I didn't mention the sources of the pictures above: SDR picture is a screenshot of Simon's SDR-console V 3.0.14 WX-map wa…

A question to the experts: I had carefully calibrated the S-meter with a signal generator in the lab. Now - how should I specify the Default noise levels in each band in de conf file of wsprdaemon? What does for example mean "Default:-10,80&qu…

Good afternoon - spent the weekend to install common-mode filters for my new active 6m vertical antenna. This antenna is a test to achieve a broadband reception with my kiwi-sdr and is now being used with wsprdaemon on a virtual machine. The vertica…

Hi, many thanks of taking my comments constructive - and fully understand, that the character of a museum is most important! And understood, that driving time and limited access time is a problem... You already have identified a lot of things - so …

Rob, I just noticed that on the Marconi T, the kiwi-SDR is heavily overloaded.... checked it at 14h50 utc today. That is the reason less spots on 160m than with the TCI 530 Check, if any pre-amp is the reason, because at the kiwi itself, signals ar…
-
Rob, with your next visit, may be you could also check the many vertical stripes in the spectrum in the higher bands on both antennas. You can see it best, when bands are closed - early local morning/nighttime... I think it is due to common-mode pro…
-
I listened at arround 2h30 in the morning local time at kph on the TCI antenna.... whow - as a European it is amazing to hear ZK1A on 160m that loud at noontime...hi Topband is very quit at kph, not much thunderstorms - we can see, that scatter eve…
-
@rrobinet - The noise graphs are a phantastic feature, Rob. Especially that you provide a website to make them public.... I spent hours to analyse the graph with the reality in my ears...hi A question: Is the graph colour (red/blue) the same as m…

ah - ok... tnx !
-
@WA2ZKD = could you arrange such progress page, please... Even antennas need some time and good wx - chasing noise sources hopefully will pay off as well... Many thanks - Ulli, ON5KQ
-
ah - great !!! However at the moment noise source chasing here... Need some time for real improvements... Ulli, ON5KQ
-
Some tweeking done: - Kiwi S-meter calibrated with my R&S lab-equipment on 20m for -73dbm signal input at the SMA of the kiwi - check whether there is a difference of S-meter reading with same generator input level, when changing bands from 2200…

good morning... I restart everything: - the VMware player with Ubuntu to reboot - Switched off kiwi and disconnect 5V and restarted it (reconnect 5V DC) - Changed wd-conf file from simple schedule to complex (last row in wsprdaemon.conf file, as I o…

Thanks for the answers for my problem with the graphs... I changed /var/www/html permissions (own it with 777 chmod rights) however still no succes. Watchdog log still shows: ------------alert in watchdog log.... Traceback (most recent call last):…

@rrobinet - Hi Rob, many thanks for the great work and support for the kiwi-hardware! I am trying to get the WD 2.5a (latest) work with my single kiwi ... on my windows 10 , I installed VMware Workstation player with fresh installed Ubuntu 18.04lt…

Unfortunately the code has been erased, which is the most important...

John, in the reversed beacon network there is obviously the same problem with google maps (as it is on wsprnet.org) Thorsten, DL9GTB mentioned the following in the rbn-forum how to treat the Google maps problem: ".... I had the same problem. …

Many thank John, for very good advice... One possibility is indeed to move the Kiwi completely outside in my Gardenhouse. Then GPS antenna can be installed easyly outside... But it needs some more work of installation necessary powerlines The outdo…

Hi everybody, I have still problems getting GPS running ... Can somebody suggest a better GPS receiving OUTDOOR antenna, as I hardly can copy more than two GPS sattelites at a time with the supplied active GPS antenna... I understand as the GPS-func…
