Free Radio Network

from Wikipedia, the free encyclopedia

Free Radio Network (FRN) (as eQSO ) is a client-server - program , which by a Dutchman for royalty-free radio applications such as CB , PMR , DMR , SRD / LPD , FRS and Freenet is designed now but also for the amateur radio is available .

The Voice-over-IP software connects both PC users and the radio stations ( gateways ) in rooms on FRN servers . The PC user uses the FRN software directly on the PC with a microphone, with the gateway the PC is linked to a radio via an interface . The interface ensures that the level of the loudspeaker output is adapted to the more sensitive microphone input and that the push-to-talk button (PTT) of the radio is pressed via a COM or USB interface.

Over the years, independent developers have developed various client systems for various end devices / operating systems in numerous programming languages. In addition to the original Windows client, various interpretations by independent developers for Linux x86 & 64, Linux ARM ( e.g. for the Raspberry Pi ), FreeBSD i386 and FreeBSD amd64 are currently known .

Especially with regard to energy consumption when operating a 24/7 gateway, the usability of a single-board computer such as the Raspberry Pi is a major step forward.

In addition to the original server software for Windows, independent interpretations are known for the previously named platforms, as well as a completely platform-independent version in Java, which even extends the original range of functions of the original server software with internal cross-links.

Due to the recurring, numerous failures of the original FRN monitor server / system manager, independent developers were thinking about the future of the Free Radio Network. In 2016 he developed an alternative FRN monitor server in Java in order to enable the Free Radio Network to run smoothly in the event of repeated system manager failures. Due to its own database , this alternative system manager is able to work independently of the original monitor server, but unfortunately this creates a parallel world that makes it necessary to re-register users and servers in this system.

With the support of the original developer of the Free Radio Network, who built an additional interface for database synchronization into his system manager software, it is now possible to use the alternative system manager without prior registration. At the moment, however, the individual users and servers are still only displayed individually in the server lists of the respective monitor.
