===== PiCQ -FRN radio gateway based on alterFRN for the Raspberry Pi ======

**PiCQ** is a so-called image for the single board computer Raspberry. The operating system used is //**[[https://www.raspbian.org/|Raspbian]]**// in the Lite version, //**[[https://github.com/JiriSko/amixer-webui|Alsa-WebUI]]**//, //**[[https://github.com/afaqurk/linux-dash|Linux-Dash]]**//, and the FRN client //**[[http://alterfrn.ucoz.ru/|alterFRN]]**//.

  * **Online** it is a FRN gateway.
  * **Offline** it is a local emergency radio/offline gateway, relay or repeater (//Parrot//).
  * **Packet radio/APRS TNC** Through Direwolf the device can be used at gateway 2, alternatively as TNC for packet radio or as APRS i-Node.

The aforementioned software was combined to a Web UI and enables the operation of two radio gateway's for the Freeradionetwork. The aim is to simplify the use of the FRN client alterFRN for a loan by operating and managing the whole system (similar to a router) via a web interface from the browser.  

During operation, the gateways can be operated via the Web UI or a radio with DTMF tones without the need to connect a monitor or keyboard to the Raspberry (headless). Room name and call status can optionally be displayed on a 4x20 character LCD display.

PiCQ now also has an emergency radio mode. This makes it possible to use PiCQ without Internet. Both gateways can be connected in emergency radio mode via a local server, which is only started then. Thus it is possible to connect 2 radio bands locally (without Internet) with each other. (e.g. CB radio and PMR)
Both gateways can also be used as parrot relays. In this mode the gateway only repeats {{ :micki.jpg?direct&200|}} a radio message it receives. However, you should pay attention to disciplined and SHORT passages in order not to occupy the frequency unnecessarily long. (A repetition of a passage needs the same time as the actual radio message)


PiCQ is currently in the test phase. Current version is PiCQ **v1.41** 
Some features at a glance:

  * Room name and RX status can be displayed on an optional LCD display
  * Emergency radio mode (//offline mode//) PiCQ can now also be operated as a local HF gateway without an Internet connection.
  * Operation as CB relay (channel 40/41) is also possible.
  * Servers and rooms can now be changed via DTMF tones from the radio.
  * Switching function via DTMF. (//With a corresponding action script, relays can now also be switched via DTMF.//)
  * Switching function via Web UI. (//The browser can now be used to switch relays.//) (Keyword: SMARTHOME)
  * Timer. (//2 relays can now be set as a timer from the Web-UI.//) (Keyword: SMARTHOME)
