Red River Radio
Protected studio circuits have both battery backups and an Eaton generator with an automatic transfer switch to keep us on the air in bad weather. Multiple data networks were set up for Axia, Internet and phones. One surprise - the electrical contractor had wired about half of these incorrectly and then didn't mark the terminations back in the engineering rooms. We ended up with a lot of unexpected toning and replacing of connections.
Red River Radio not only uses a satellite downlink for network programming, but we also use the same dish as an uplink to the PRSS which serves as our STL to our transmitter sites. This enabled us to decommission all of our microwave hops while at the same time maintaining an extremely reliable relay of programming. Radyne DMD20s at all sites effectively create our own private data network from ground to satellite to ground.
Audio processing is accomplished with Omnia units. We have an ample number of Axia nodes for interconnecting devices and these ultimately send AES audio to the Omnias. From the Omnia processors audio data goes to our Harris Importer and Exporter and then out to the satellite system.
In the short time we have been in our new studios we have received many compliments on our improved sound and have had very few technical glitches, at least those of the kind that can be heard by our audience. We've already held a half-dozen live music events and these have validated the extra trouble we went thru for the performance studio. The long hallways on either side of the performance studio have been turned into galleries for visual artworks, which are changed quarterly. In short, our goal of creating a versatile facility to provide excellent audio, more production capacity and ease of use while being visually attractive for the community has been well accomplished.
