Clint has written up an installation blog at: http://ka7oei.blogspot.com/search/label/KiwiSDR
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.

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'

Version 1.1e has been in reliable service at a number of sites for a week. To summarize a clean installation:

1) create the directory /home/pi/ham/kiwiwspr

2) copy kiwiwspr-1-1e.sh to /home/pi/ham/kiwiwspr/kiwiwspr.sh

3) run "chmod +x /home/pi/ham/kiwiwspr/kiwiwspr.sh"

4) run: "/home/pi/ham/kiwiwspr/kiwiwspr.sh -h" until you are no longer prompted to install any of the following programs:
The program will prompt you to install kiwirecorder.py. Download it from https://github.com/jks-prv/kiwiclient/tree/jks-v0.1 to /home/pi/ham/kiwiwspr/kiwiclient-jks-v0.1
The program will prompt you in install WSJT-x from http://www.physics.princeton.edu/pulsar/K1JT/wsjtx.html
The program will prompt you to install 'bc' by running: 'sudo apt-get install bc'

5) Edit the prototype configuration file '/home/pi/ham/kiwiwspr/kiwiwspr.conf' created during step #4 to reflect:
a) The name for your Kiwi(s), their IP addresses and Grid locator
b) The schedule of WSPR bands for it to spot. Configure only hour '00:00' if you want the same configuration 24/7

6) run "./kiwiwspr.sh -j a" to start the capture jobs defined in your kiwiwspr.conf

7) print the status of your jobs by running "./kiwiwspr.sh -j s"

Once "./kiwiwspr.sh -j s" lists capture and decode daemons for each of your configured bands:

8) run "./kiwiwspr.sh -w a" to start the watchdog daemon which will every 2 minutes verify that your jobs are still running and execute the configuration changes defined in your kiwiwspr.conf
"./kiwiwspr.sh -w a" will also configure your Pi so the watchdog daemon runs every time your Pi is powered up or rebooted.

Finally, each job writes 200 Kbps of wav data to files in /tmp/kiwi-captures/... If that file tree is at its Pi default location on the microSD, this writing will significantly shorten the lifetime of the microSD. To avoid that wear, configure your Pi's /etc/fstab to make /tmp/kiwi-captures/ a ramdisk file system:

pi@PiKPH:~/ham/kiwiwspr $ tail -2 /etc/fstab
### For kwiwwspr.sh capture files
tmpfs /tmp/kiwi-captures tmpfs defaults,noatime,nosuid,size=100m 0 0
pi@PiKPH:~/ham/kiwiwspr
