Re: FST4W support in WD

Edward Hammond
 

I may not be a "top" station, but I think I'm holding my own for a newbie.  And I have improvement plans for mid-2021.

FSTW4W support would provide a great excuse for building an LW/MW antenna and dedicating a Kiwi to it in March or April.

My wife's gonna love it!

Thanks for all your work Rob.

Let me know if you have a more immediate need for it.

Re: Obtaining date/time from the Kiwi's GPS [fixed in v1.417]

jks
 

From the v1.427 release notes:

    Added gps_date parameter to /status query. "gps_date=<enable>,<set>" where <enable> and
        <set> are digits '0' or '1' indicating if gps is enabled to set date/time, and if
        the set has actually occurred.
 


Re: Major update to WsprDaemon Timescale Database Guide V2

Hi Gwyn,

many thanks for all that excellent work ! I am sorry to reserve more time into the data analysis yet - but silently using with great pleasure, what you have done on the log2 server.

I was just too busy with setting up my extensive winter antenna set-up... But winter holiday is cancelled due to Corona and the long winter evenings will offer possibly more time for the shack and also more data analysis, for which I have great interest...

Many thanks,

Ulli, ON5KQ

I've updated and expanded my Guide to the WsprDaemon Timebase installation. It's attached as a file to this message and available via the WsprDaemon Timescale web page. The Guide is now fully consistent with the installation on the logs2.wsprdaemon.org server. It includes many new examples of postgreSQL queries and has Annexes outlining APIs for a range of methods to access the data. I'm grateful to Phil, VK7JJ, for contributing an Annex on how he uses node.js. Other routes include Python, psql, KNIME, and Octave (Win 10 and macOS proven so far).
If you spot errors, or parts are not clear, please let me know.

V2.10i fixes installation on Ubuntu 20.04.1 LTS

Rob Robinett
 

If your WD is running, then there is no need to upgrade to this version.


Re: Delayed Kiwi connection problems should be fixed in V2.10h

ON5KQ
 

Rob,

I think my start-up problem has been solved as I could download and install the kiwirecorder script.

I also found, that the establishment of receive channels of the kiwis now happens almost instantly. As my set-up grows while building some better antennas I run currently 32 channels on 4 different antennas. It works without problem now on my Dual-Xeon Supermicro Workstation.

Ulli, ON5KQ

I think I found and fixed that problem which has been reported by several users.
Let me know if you still experience rx channels which come up only after some minutes, or never at all.

Re: V2.10h has been checked in

I would need to ssh to that system to diagnose your problem.


Re: V2.10h has been checked in

Just to add a little detail (maybe save some time).
I just did a clean git pull and run on a debian 10 VM (no previous version has been on there before).
All seemed to install without error and appears to run but only passes 60 Bytes to the Kiwi every so often.
Digiskimmer on the same Debian can connect and run OK so don't think it is networking.

Thanks Glenn. Maybe Rob is traveling. I missed last weeks meeting to know if there had been a schedule change. I can guess that we will hear here soon.

Re: V2.10h has been checked in

Rob,
I am now running on the raspberry pi version 2.10g - as I have only one antenna it is ok for now.
Is there a way to do a clean re-install of wsprdaemon without re-install Ubuntu ?

Ulli


Re: V2.10h has been checked in

Rob Robinett
 

I have verified the installation on several Pi/Buster and i86 Ubuntu 18/20 servers.  Give me ssh access to your server and I'll look at your installation problems.

Why this ???

Everything worked before but the new version... ;-((((

What happens with the script ???

Hi Rob...

after all the work with tree cutting and winter work in the garden - today I put a simple dipole to just have something,...

Unfortunately the new 2.10h completely broke my installation.... no kiwirecorder can be found, no python numpy anymore... what happens with that update ???

Everything worked great, but 2.10h grounds me....

Ulli

Earlier today I checked in a fix for a problem with WD failing to connect to Kiwis during startup.  The was due to a race condition which only appears on very fast servers, e.g. a quad core i7.  

If your installation is running reliably, then there is no need to 'git pull' v2.10h.

HTML Query Examples

Rud K5RUD
 

I am interested in obtaining WSPR spot reports without running the database. The Python script at the end of the TimeScale documentation is what I want to do. 

I don't know Python sufficiently to develop the system I want. I would like to do this in Node.js. 

Can someone provide some example HTML lines?

Re: Obtaining date/time from the Kiwi's GPS [fixed in v1.417]

jks
 

It occurs to me now that some additional information from the Kiwi is probably necessary to make this new scheme useful. There needs to be an indication, probably from the /status URL, that GPS date/time set mode has been selected and also when it actually happens. The latter due to the long delay (up to 12.5 minute) possible before the GPS set is even possible. You might want to be suppressing spot uploads before this point in case the power-up date is wrong.
