Hampi Utilities
This is a collection of utilities for the Hampi image. These scripts will only work on the Hampi image. Some scripts are specific to the Nexus DR-X board.
Installation
Easy Install
- Click Raspberry > Hamradio > Update Pi and Ham Apps.
- Check hampi-utilities, click OK.
Manual Install
Alternatively, you can install these utilities manually as follows:
-
Open a terminal and run:
cd ~ rm -rf hampi-utilities git clone https://github.com/AG7GN/hampi-utilities sudo cp hampi-utilities/*.sh /usr/local/bin sudo cp hampi-utilities/*.desktop /usr/local/share/applications/ cp hampi-utilities/hampi-utilities.version /usr/local/src/hampi/ rm -rf hampi-utilities
check piano
This script is called by initialize-pi.sh whenever the Pi starts. It reads the position of the piano switches on the Nexus DR-X board and launches a script based on which switch levers are up or down.
The script that check-piano.sh calls must be in the user's home directory, be marked as executable, and be named pianoX.sh where X is one of these:
1, 12, 13, 14, 123, 124, 134, 1234, 2, 23, 234, 24, 3, 34, 4
Example: When the piano switch levers 2 and 4 are down, the script named $HOME/piano24.sh will run whenever the Raspberry Pi starts.
If a pianoX.sh script is not present, no action is taken and the pi boots normally.
initialize pi
This script is run whenever the Pi starts. It runs via this line in user pi's crontab:
@reboot sleep 5 && /usr/local/bin/initialize-pi.sh
The script checks for the presence of a file called DO_NOT_DELETE_THIS_FILE in the user's home directory. If the file is present, the script runs check-piano.sh and then exits.
If DO_NOT_DELETE_THIS_FILE is not present in the user's home directory, the script will reset various configuration files for ham radio applications to default values and reset the VNC Server and SSH keys.
name radios
This script allows the user to change the title bar of Fldigi suite and Direwolf applications so they say something other than "Left Radio" or "Right Radio". The associated menu item file is nameradios.desktop.
patmail
This script allows the user to run pat within scripts rather than interactively. Obviously, pat must be installed for it to work. You can install Pat via Raspberry > Hamradio > Update Pi and Ham Apps.
test piano
This script allows you to test the operation of your pianoX.sh script by simulating what the check-piano.sh does when the Pi starts. Set the piano switches as desired, then open a Terminal and run test-piano.sh. The script will tell you which script will run based on which switch levers are down. It will not actually run the pianoX.sh script.
tnc left tnc right
These configuration files are required by /usr/local/bin/tnc.sh script. They contain the configuration that tnc.sh needs in order to operate with Direwolf as an APRS Digitpeater, iGate, Digipeater+iGate, or ax25 TNC.
tnc.sh will look for tnc.conf in the user's home folder. To use tnc.sh, you must make a symlink to the appropriate tnc configuration file for the left or right radio.
-
For the left radio:
cd ~ ln -s tnc-left.conf tnc.conf -
For the right radio:
cd ~ ln -s tnc-right.conf tnc.conf
IMPORTANT: You must edit tnc-{left|right}.conf with your own settings.
tnc
This is a script that launches Direwolf, and optionally other related apps, in different modes. The script will look for tnc.conf in the user's home directory. The script will set up Direwolf to operate in any one of these modes TNC: ax25, APRS Digipeater, APRS iGate, APRS Digipeater+iGate. It can also launch pat, ardop, pat+ax25, or pat+ardop provided those apps are also installed and configured.
trim scripts
trim-fldigi-log.sh
trim-flmsg-log.sh
trim-flrig-log.sh
trim-fsq-audit.sh
trim-fsq-heard.sh
This collection of scripts trims the logs of various applications in the Fldigi family. They all take 1 argument: A date reference, for example: "10 days ago" or "1 hour ago". The script will delete log entries older than the date specified. These scripts are run whenever you launch Fldigi, Flrig and Flmsg from the Raspberry > Hamradio menu. You can change the timeframe of the trim by editing the .desktop. file. For example, this is the Exec entry in the /usr/local/share/applications/fldigi-left.desktop file:
Exec=sh -c '/usr/local/bin/trim-fldigi-log.sh "yesterday";PULSE_SINK=fepi-playback PULSE_SOURCE=fepi-capture fldigi --config-dir /home/pi/.fldigi-left -title "Fldigi (Left Radio)" --flmsg-dir /home/pi/.nbems-left'
To change it to trim log entries older than 2 weeks ago rather than yesterday, the line would look like this:
Exec=sh -c '/usr/local/bin/trim-fldigi-log.sh "2 weeks ago";PULSE_SINK=fepi-playback PULSE_SOURCE=fepi-capture fldigi --config-dir /home/pi/.fldigi-left -title "Fldigi (Left Radio)" --flmsg-dir /home/pi/.nbems-left'
watchdog tnc
This script is run via cron. It launches tnc.sh and restarts it automatically if it stops for some reason. It is intended for use when tnc.sh is run in one of the APRS modes. The script takes one argument, which it passes on to tnc.sh as the "mode" argument. These are examples of entries you could use in crontab (only ONE can be used at one time):
# This one digipeats only - no internet
*/2 * * * * /usr/local/bin/watchdog-tnc.sh digi >/dev/null 2>&1
# This one digipeats and igates
*/2 * * * * /usr/local/bin/watchdog-tnc.sh digiigate >/dev/null 2>&1
# This one igates only
*/2 * * * * /usr/local/bin/watchdog-tnc.sh igate >/dev/null 2>&1
