The idea was learned from wsprdaemon, yet FT8 mode is more and more popular nowdays, more signals, easer to pickup(compared to wspr, some people use maga watt to transmit FT8).
This can be useful in determining propagation conditions or in adjusting antenna. A wide band antenna kiwisdr located in urban area in my case, with 10 bands requests at the same time, can be easily reach over 10,000 spots within 24 hours.
It is also interesting to see how long it takes to spot 100 different DXCC/countries. (A well placed station with a decent antenna can do this within a week of monitoring, but the best systems can do it within a single day).
This is a console application and it looks just like:

If you have a running docker setup you should quite easy to get started.
docker run -eTZ=`cat /etc/timezone` -v digiskr:/opt/digiskr --tmpfs=/tmp/digiskr lazywalker/digiskrYou should see out just like:
Timezone is Asia/Shanghai
2020-08-14 09:44:47,077 WARNING 1 [main] No tasks in queue.
2020-08-14 09:44:47,077 WARNING 1 [main] I'm out
Edit /var/lib/docker/volumes/digiskr/_data/settings.py, follow the Configuration section below, then run it again, if everything well you should see:
2020-08-14 01:49:15,124 INFO 1 [main] current schedule is: {'szsdr': ['20!']}
2020-08-14 01:49:15,125 INFO 1 [main] QueueWorker QW-0 started

2020-08-14 01:49:15,127 INFO 1 [main] Started sound recorder szsdr-20!, timestamp=1597369756
You are good to go.
FYI, Here is a quick setup guide for Raspberry Pi, for short, all you need to do is run curl -sSL https://get.docker.com | sh
TIPS: DO NOT use over 8 simultaneous tasks when you using docker on raspberry pi, it may cause memory leak to your kiwi.
If you want to do it manually follow those steps.
To do so, first you need to install WSJT-X, the client that most people use for decoding FT8.
I use the jt9/wsprd command-line program within the WSJT-X to decode signals, then upload to http://pskreporter.info and http://wsprnet.org when work with wspr.
Download & Install WSJT-X from http://physics.princeton.edu/pulsar/k1jt/wsjtx-2.2.2-Darwin.dmg, open a terminal, then
sudo ln -s /Applications/wsjtx.app/Contents/MacOS/jt9 /usr/local/bin/jt9
sudo ln -s /Applications/wsjtx.app/Contents/MacOS/wsprd /usr/local/bin/wsprdI only tested debian 11 - bullseye/sid, cause only this version have a ready-to-go wsjtx-2.2.2 package.
sudo apt update
sudo apt install wsjtxDigiSkimmer is write in python3, make sure python3 is your default python interpreter, then you shoud install numpy and requests libraries
pip install requests numpyPull the code
cd ~
git clone https://github.com/lazywalker/DigiSkimmer.git
cd DigiSkimmerYou should modify settings.py
cp settings.py.template settings.pyif you upgrade from below v0.20.5, please do remember to copy your settings from the old config.py into settings.py, filename changed, sorry.
STATIONS is what kiwistation for, SCHEDULES is for the station/band hop, available bands are:
FT8: 10 12 15 17 20 30 40 60 80 160
FT4: 10 12 15 17 20 30 40 80
WSPR:10 12 15 17 20 30 40 80 160 630 2190
Configure your stations
STATIONS = {
'szsdr': { ## name of kiwisdr station
'server_host': 'szsdr.ddns.net', ## url of your kiwisdr station
'server_port': 8073, ## port of kiwi
'password': 'passwor0d', ## password if needed
'tlimit_password': 'passwor0d', ## password to bypass time limited, if needed
'callsign': 'BD7MQB', ## your callsign
'grid': 'OL72an', ## your grid/locator, if none set will use the kiwisdr's setting
#'antenna' : 'Longwire/Mini-whip' ## if none set, it'll read the antenna information from the kiwisdr
},
...
# more stations goes here
}
SCHEDULES = {
'21:00-08:00': {'czsdr': [20, 30, 40, 60, 80, 160]},
'08:00-14:30': {'czsdr': [10, 12, 15, 17, 20, 30]},
'14:30-21:00': {'czsdr': [10, 15, 17, 20, 30, 40]},
...
}UPDATE: digiskr support band hop, you can use a specific slot(or more) to rotate between bands, this feature is very helpful when you don't have enough slots.
- Use
|to enable band hop, see the config below, 4 slots will be used, the last one is rotate between 60-80-160, one per minute. - You can also specific what mode to spot,
~for FT8(by default),+for FT4,!for WSPR. - When using
'or|, always remember to quote the band by'
SCHEDULES = {
# four slots all FT8, the last one is rotate between 60-80-160 when localtime is 21:00-08:00
'21:00-08:00': {'szsdr': [20, 30, '40~', '60|80|160']},
# when localtime is 08:00-12:00
'08:00-12:00': {
# station no.1, slot1 is rotate between 20(FT8)-20(FT4), slot3 is 40(FT8)-40(FT4)
'szsdr': ['20|20+', 30, '40~|40+', '60|80|160'],
# station no.2, slot1 is rotate between 10-12-15-17-20-30-40 at FT8 mode, then 20-30-40 at FT4 mode
'czsdr': ['10|12|15|17|20|30|40|20+|30+|40+'],
# station no.3, slot1-4 working 10m/20m/30m/40m with WSPR mode at the same time,
# slot5 rotate from 20m to 40m with FT mode.
'cdsdr': ['10!', '20!', '30!', '40!', '20+|30+|40m'],
}
...
}./fetch.pyBTW i use tmux to keep fetch.py running when console closed.
