+ | Here is a simple way to Unipager-Audio transmit your callsign announcement, as required by law in many countries. | ||
+ | First, create a .wav file with the desired announcement. It can be CW or speech, on your choice: | ||
+ | * To create a CW .wav file visit: http://www.meridianoutpost.com/resources/etools/calculators/calculator-morse-code.php | ||
+ | * To create a voice .wav (in 17 different languages) visit: https://ttsmp3.com/ | ||
+ | * Convert the .mp3 to .wav (if needed) visit: https://online-audio-converter.com/ | ||
+ | * Rename your .wav file to "callsign.wav" | ||
+ | |||
+ | Once you have the wav file, login to Unipager OS host over SSH terminal (eg. Putty) and type the following commands: | ||
+ | |||
+ | sudo -i | ||
+ | mkdir /unipager | ||
+ | chmod 777 /unipager | ||
+ | cd /unipager | ||
+ | touch callsign.sh | ||
+ | nano callsign.sh | ||
+ | |||
+ | The nano editor will be openend, so paste the following content: | ||
+ | |||
+ | #!/bin/bash | ||
+ | # CALLSIGN SCRIPT | ||
+ | sleep 30 | ||
+ | service unipager stop | ||
+ | sleep 5 | ||
+ | echo 1 > /sys/class/gpio/gpio1/value | ||
+ | sleep 1 | ||
+ | aplay /unipager/callsign.wav -D plughw:1 | ||
+ | echo 0 > /sys/class/gpio/gpio1/value | ||
+ | service unipager restart | ||
+ | |||
+ | Press Ctrl-X, then press Y to save the content. | ||
+ | |||
+ | <color #ed1c24>IMPORTANT:</color> The "-D plughw:1" parameter is meant to systems using external USB soundcard. If using Raspberry native soundcard this parameter can be suppressed. | ||
+ | IMPORTANT: this script opens GPIO1 to act the PTT. Use the same GPIO declared on Unipager-Audio configuration. | ||
+ | |||
+ | Still on terminal type "crontab -e" to open the scheduler configuration, then add the following line to the end of file: | ||
+ | |||
+ | */10 * * * * sudo /unipager/callsign.sh | ||
+ | |||
+ | Press Ctrl-X, then press Y to save the content. | ||
+ | |||
+ | Now find a way to transfer the callsign.wav file from your computer to the /unipager folder on unipager host, the easiest way is using WinScp software (or use wget, ftp, etc) | ||
+ | |||
+ | Type the command | ||
+ | chmod 777 * | ||
+ | |||
+ | Type the command | ||
+ | reboot now | ||
+ | | ||
+ | <color #ed1c24>Beware that this solution only waits for 30 seconds to empty the UniPager queue. On cases with high traffic and/or only few available time slots this may lead to loss of messages!</color> | ||
