Welcome
Rob Robinett
I have created this group to communicate with users of my Wsprdaemon (WD) WSPR recording program.
See www.wsprdaemon.org for details about installing and using WD and exploring the spot data services associated with it. Rob

Re: Welcome
ON5KQ
Good idea! - welcome...
Currently lots of problems here with my 40m transmissions. The TX-ant shows faults of connection problems - the usual problem how to reliably connect copper(wire) with Aluminium (tubes). However the current terrible rain/storm weather doesn't permit any antenna service/maintainance at the moment. See you in the evening meeting this wednesday... Clints latest post in his blog about the kfs receiver equalization filters he has made. is excellent and very useful for many, I think... Some background, history and theory about such filters can be found at wikipedia also... https://en.wikipedia.org/wiki/Zobel_network Amateurradio is sometimes about very ooold technology... so old that it vergotten...hi Ulli, ON5KQ

KFS Four channel Kiwi system
craigmc@...
Now available is a four channel Kiwi system at KFS, Half Moon Bay, CA. Each Kiwi receiver is connected to a different TCI antenna; Omnidirectional, Northwest Sector, Southwest Sector, and Southeast Sector.
A Landing Page where you can select between antennas is here: http://69.27.184.58:8080/ Feel free to pass this link to others. Enjoy! Rob’s wsprdaemon is gathering data on all four antennas. Craig, W6DRZ

MP1584 Buck converter 3A
ON5KQ
I purchased the buck converters to step down from 12V DC to 5V DC to power the kiwi-rx
Many vendors are selling them on Amazon and e-bay As they arrived I am astonished, that the Buck converter modules do not have the potentiometers installed as shown on the pictures on the Internet. I was afraid, they would not be useful, in case the output voltage is not 5V. I was lucky however - a quick test with 100mA load showed 4.99V DC output with 12.3V DC input - so even without potentiometers they may be used. Question: I am afraid, that if something wents wrong with the small modules, the full 12V DC may reach the Kiwi power input plug. What should I do best to protect the kiwi for overvoltage when using the small ? Any good effective idea which would prevent big damage to the kiwi ? Thanks for some advice, Ulli, ON5KQ

I have accidentally applied 12V to the Kiwi without experiencing any damage. I know there is circuitry in the BB to protect ti from over voltage, and it appears the Kiwi board itself has protection as well.

Re: MP1584 Buck converter 3A
ON5KQ
Rob,
I made a short test: - 13.0V DC supply from a switch mode power supply by Meanwell : Type S-100F-12 https://www.meanwell-web.com/nl-nl/ac-dc-enclosed-power-supply-output-12vdc-at-8-5a-s-s--100f--12 I know this unit is a bit noisy and noise can be seen in the receiver, if used with antenna relais, etc... However I have it in the shack, doing nothing... and it can deliver a lot of Amps... The output of this SMPS to the input of the buck DC-DC converter - nothing to adjust for 5.0V output - then a 1inch long smal cable into the kiwi Result: - No ant connected: absolutely no noise at all visible from DC to 30Mhz... really absolutely NOTHING. The result was absolut the same than my linear power supplies and much better as shown by Clint during the video-conference. - connected my relatively large vertical active dipole (2x3.5m with LZ1AQ pre-amp) - after 15db attenuator in front of the kiwi...: I cannot find any carrier or noise from the power supplies. It is interesting, that also the Meanwell SMPS does not harm at all... So - this is really a good solution I think and I will use it at the new location... Ulli, ON5KQ PS: The linux PC is my mobile laptop... I must re-install it anyway and will come back to you, if the WD-installation problem persist. I then can also provide remote access, if this would help...

Kiwi As Your Time Server
jimcny2
On Client:
sudo apt-get install ntpdate sudo ntpdate -u yourkiwiaddress Kiwi needs no mods. Port should be open on lan.

Re: Kiwi As Your Time Server
Rob Robinett
I have just been studying how to configure the WD server to use the Kiwi's NTP service.
It seems that WD should leave its time and ntp service alone if 'ntpq -p' reports that ntp is synced via an Internet connection. But if the WD server is not connected to the Internet, and the Kiwi's sw_version is v1.413 or later, and the Kiwi reports the Kiwi is in gps lock, then WD would instruct its ntp service to add the Kiwi to its list of ntp servers. Not having a Kiwi in my office this morning, I have no way to test if 'ntpdate -u yourkiwiaddress' would do that.

Re: WD v 2.10d is published
Hi everyone.
I found I had to change my apt sources from Buster to Bullseye for what was Raspbian (now called "Raspberry Pi OS") to get certain packages needed for the latest WSJT-X. Not the worst thing in the world, but worth noting. I'm happy enough running testing on my devices, but I won't be heading to unstable anytime soon.. My setup appears to be working as expected, happily sitting inside the top 30 decoders worldwide.

Princeton filtering some IPs - can't directly download WSJT-X
Just as an FYI for some people, that the www.physics.princeton.edu webserver does not serve traffic to certain IPs or certain IP ranges.
How did I find this out? Guaranteed time outs from my home network trying to access anything on that server. Enabling either my VPN or my utilising a proxy tunnel over SSH to the local University campus network allowed immediate and fast transfer of the pages and the files. I ended up having to set wget_proxy on my Pi with an SSH tunnel to the computer society of my alma mater in order to get the update script working as expected. Once that was done it proceeded without issue. I have seen reports on the net about others having issues downloading the WSJT-X software for similar reasons. Does anyone know an admin on the server to get a verification that traffic is filtered, and how to get some IP blocks unfiltered? -Cathal

WD service stops ?!
ON5KQ
As I am in the process to start up the receiver after relocation, I updated/upgraded the long not used Raspberry... I was astonished about the HUUUUUGGGE update...
I thought it is time to "git pull" to also use the latest update of WD on the raspberry ... The result is.... NO uploads at all ! Is there something wrong with the new wsprd decoder it downloads as well ?? It is so strange that I even do not know, where to start ? Should I make a new install from scratch ? But that doesn't work either, as Numpy and a lot of other packages won't install as I found on my Ubuntu machine... I tried the procedere to look for the upload file, as mentioned in the old folder... It only shows the fact that verbosity is 1.... but no information about how many decodes are in the last 2min interval and if there is something uploaded.... no information at all.. It seems to me, that the service is not running at all although it says everything runs (wsprdaemon.sh -s).... Any good idea, what I should do ? Ulli, ON5KQ

Re: WD service stops ?!
Rob Robinett
Your linux server is probably missing a library needed by the new wsjt-x decoder. I am dealing with a neighborhood power outage, so I can't look at your system right now. What cpu/OS are you using?

Standard Raspberry pi 4
It downloaded a huge system update after: "sudo apt upgrade" after reboot and WD restart - no uploads anymore... Ubuntu 20.04 on my laptop don't work either... Numpy doesn't install (but the Laptop with Ubuntu 20.04) is a different story to be solved seperately I keep the raspberry running - so you might look at it, if the power failure will be solved...

Re: WD problems
ON5KQ
With the latest system updates of the pi and latest update WD (git-pull), I think there is a problem with the python3-numpy package. pi@ON5KQ-Pi4:~/wsprdaemon $ ./wsprdaemon.sh -a
|
|
|
|
Re: WD problems
ON5KQ
Ok, I did the following:
run: pip3 uninstall numpy # remove previously installed version
apt install python3-numpy
There are sometimes issues reported on Raspberry Pi setups when installing using libf77blas.so.3: cannot open shared object file: No such file or directory
The solution will be to either: sudo apt-get install libatlas-base-dev
to install the missing libraries expected by the self-compiled NumPy (ATLAS is a possible provider of linear algebra).

Re: WD problems
ON5KQ
I switched off the kiwi and reboot it.
The fault message with the kiwirecorder (see above) disappeared.... however no decodes, no spots The terminal "top -c" shows the wsprd executing and calculating rather long for 35sec only a single band (now switched to 40m most busy band for one channel simple schedule) But after all the calculations no decode..
