   * Radio Frequency POCSAG – Enter the POCSAG radio frequency. Per Andy Taylor in the Pi-Star User Forum : "If we get good buy in from repeater keepers, we could have a really good paging network with great coverage, especially if we all use the same standard frequency."​ In Germany, where are already a lot of repeaters we use 439.987.500MHz,​ which will be the deafault entry in Pi*!   * Radio Frequency POCSAG – Enter the POCSAG radio frequency.

 +  * POCSAG Whitelist - This is a white list filter. You can enter RICs separated by a comma. Only calls to those RICs will be transmitted on the air. You can for example enter your own RIC here to only transmit calls to yourself. Beware that group calls, time sync messages and the like will be suppressed if you do not enter the corresponding RICs here as well.

 +===== Troubleshooting =====
 +
 +Sometimes the DAPNETGateway-service got stuck when loosing internet-connection. This results in an error-state on the status-page of the transmitter at hampager.de. Unfortunately the service would be still running but not reconnecting.
 +
 +If you would like to implement a watchdog that restarts the service, if the transmitter goes into error-state you could use following script, that could be called every 5 minutes for example by crontab:
 +
 +
 +        #!/bin/bash
 +        RETVAL=$(curl -u <​username>:<​password>​ https://​hampager.de/​api/​transmitters/<​yourtransmittercallsign>​ | egrep -h "​OFFLINE|ERROR"​ | wc -c)
 +        if [ "​$RETVAL"​ -gt 0 ]; then
 +                sudo systemctl stop dapnetgateway.service > /dev/null 2>&1
 +                echo restarting dapnetgateway
 +                sleep 5
 +                sudo systemctl start dapnetgateway.service > /dev/null 2>&1
 +        fi
 +
 +Remember to switch the sd-card to read-write-access with ''​rpi-rw''​ before creating the file in your home-directory. Also remind to make it executable with ''​chmod +x yourscriptname.sh''​
 +
 +**Fehlerbehebung Telekom Router**
 +
 +Ein weiterer Fehler trat bei Telekom Routern auf.
 +Die Router W922 V und W925 V (vielleicht auch noch weitere) haben eine Sicherheitseinstellung,​ dass sich regelmäßig die IP Adresse ändert. ​
 +Dadurch wird die Internetverbindung zum MMDVM unterbrochen und nicht wieder neu aufgebaut.
 +Durch ausschalten der der Sicherheitsfunktion im Router ist das Problem behoben.
