This is a major upgrade in functionality, reliability and installability from previous versions of wsprdaemon and its predecessor kiwiwspr.sh
Configured to connect to two Kiwis configured in 8 channel mode, it easily simultaneously decodes all 14 WSPR LF/MF/HF WSPR bands during every two minute cycle and reliably uploads spots to wsprnet.org

To install it:

1) login to the Pi as user 'pi' (or other non-root user) and create the directory '~/wsprdaemon'.
2) copy the attached file to that directory, rename it to 'wsprdaemon.sh', and make it executable with 'chmod +x '
3) cd to that directory and execute it: './wsprdaemon.sh'. It should walk you through the installation of all of the utility programs it needs and create a prototype 'wsprdaemon.conf' file
4) edit the wsprdaemon.conf file following the directions in it
5) to start the daemon: './wsprdaemon.sh -a'
6) to see the daemon status: './wsprdaemon.sh -s'
7) to stop the daemon: './wsprdaemon.sh -z'
8) for help about the daemon: './wsprdaemon.sh -h'

During installation it creates a tmpfs files system '/tmp/wspr-captures/...' where all of the recordings and logs are kept, so 24/7 recording of 14 bands => 3 Mbps of wav files doesn't wear out your microSD in a few months
It also modifies the systemclt files so the daemon will autostart during a powerup or reboot.

I have tested installation and operation on a clean 'Stretch' OS. The script can run in other Debian servers, but installation may require some custom tweaks.

I built VHF/UHF band support into kiwiwspr and wsprdaemon and will add support for downconverters if there is an active user.

However I have a much updated version of wsprdaemon.sh to release in the next few days which I hope will also simplify installation.

$15 8-way moca splitter works great for me. I got a bag of F to SMA adapters to connect it to the Kiwis. No extra bias-t HW required.

I bought but have not yet deployed two of the $150 High Sierra Microwave downconverters Jim described http://www.hsmicrowave.com/sdr.html, one for 6M and another for 70cm. They will customize the input frequency and include all the filtering, but you will need to supply a LO. For WSPR a high stability GPSDO LO like the $150 Leo Bodnar would be needed, but for other modes that would be over specced.

In future versions I will make it possible to suppress the registration of the service to run at startup. Unfortunately I see no way to merge the recording, decoding and posting into a single thread. So monitoring and diagnostic printouts would be jumbled together if they were all going to stdout or stderr. Still, I like your attempt to simplify installation and will consider how to address it. I am currently working to expand the supported receivers beyond the Kiwi so that VHF/UHF signals can be spotted by RTL-SDRs and other receivers, but the Kiwi is the best and cheapest receiver for LF/MF/HF reception.

The next version of kiwiwspr logs its name along with the spots, so we can download the database zip files and see who is running kiwiwspr

I have attached version kiwiwspr.sh 1.1g which includes a number of significant enhancements. The most important in my judgement is that it now tests the version of wsprd and if wsprd 2.0 is installed it is run with command line flags which will result in 10% more spots from the same captures.
You can obtain that new wsprd by downloading to your Pi the WSJT-x 2.0 release candidate from the WSJT-x web site. I am told we can expect no further ?hanges in the wsprd included in the current RC3 package.
To install this version, download this file to your Pi and rename it to kiwiwsr.sh and then replace your current kiwiwspr.sh with the renamed version.
Verify the version you are running with "./kiwiwspr.sh -V'

Thanks. It is gratifying to be part of such an active and dedicated group.
Everyone using the Kiwi, especially for WSPR, should upgrade to v 1.242. It corrects a bug which introduced -40dB +/- 23 Hz sidebands to spots of > +10 dB SNR. Even more important, it appears to have improved SNRs by about 2 dB which means the Kiwi will detect low SNR spots which it missed before.
