WebRig

Webrig is web application that allows remote control of hamradio transceiver. It uses today's web technologies like HTML5 and AJAX to provide same experience as desktop application. It does not transfer audio.

Current state is proof of concept.

Principles of operation

Webrig consists of some small PHP scripts. It should run on any web server (apache) with PHP support. To access rig (transceiver) it uses hamlib utility rigctl. WebRig is calling rigctl periodically to read rig state like frequency, mode etc. When user changes rig settings, WebRig sends appropriate command to radio. Because of using of rigctld daemon, more users can access the rig simultaneously.

How to install

• Download the archive from http://ok1zia.nagano.cz/webrig/ and unzip they into tree of webserver (maybe /var/www/webrig).
• Install hamlib utilities: sudo apt-get install libhamlib-utils
• Search for model number of your rig: rigctl -l. Next text assume 311.
• Test if hamlib can communicate with radio: rigctl -m 311 -r /dev/ttyUSB0 f. This command should return current frequency. In case of problems try to add -vvvvv command to show verbose informations.
• When you discover proper options, put they into system() command of rigctl.php:

system("rigctl -m 2 -- $q");

• Mofify also command popen(). Change ONLY rig model to REAL rig (no rigctld). This command does not connect, it only dumps rig model capabilities.

if ($_GET['q'] == '-uf'){                                       |
   $fd = popen("rigctl -m 229 -u", "r");
   ...
}

• Run rigctld: nohup rigctld -m 311 -r /dev/ttyUSB0 &. Ampersand means command is run on background. If you want to stop it, use killall rigctld. Good way is add this command to the end of /etc/init.d/rc.local script (or similar, depends on your distribution).
• Connect to server using web browser.

• Low orders - what happen to lower order digits when you tune. Possibilities are Keep and Clear.
• VFO set - if use VFO's A+B or Main+Sub
