I remember, back in the day, when we all used Scientific Atlanta 7300 satellite receivers. There were two flavors of decoder cards; DATS and SEDAT. Starting about 1982 or so, satellite distribution of network audio was a quantum leap over the old TELCO circuits used previously. The use of satellite downlinks allowed radio stations to receive an almost unlimited number of programs from every network under the sun.
The SA 7300 receivers gradually gave way to the SA 3640, which gave way to the Starguide, Starguide II and Starguide III series which finally lead to the XDS and MAX receivers used today.
The newest generation satellite receivers are yet another quantum leap over the last, with on board hard drive storage that allows time shifting of entire shows. Another nice thing is the web interface. Before you know it, everything in the broadcast plant will have a web interface.
The one issue I have had with nearly every single XDS receiver is the fan going bad. The manufacture must have laid into a supply of defective fans. A bad fan is noted with the fault light turns red and the unit will return a “Fan stopped” error message. The network will send a replacement fan if you let them know. I have carefully replaced several of these fans without turning the receiver off.
Otherwise, the web interface is pretty intuitive. Drop down menus allow for programming the audio ports on the receiver and setting up the delayed recording and playback function.
Any required network closures are configured in the relay screen. The programming clock provided by the network will specify which relays are used for each show.
Each receiver has two DB-37 connectors that have 16 relays each for a total of 32 output closures. That should be enough to cover almost any programming situation.
Finally, the receiver’s overall operating condition can be monitored via the health screen:
Something like this can greatly speed up any remote diagnostic trouble shooting by eliminating (or pinpointing) a satellite system failure as the reason for a station being off the air. I also make sure that all automation systems have some type of remote access like VNC so that I don’t have to needlessly drive to the studio to fix a silly computer problem.
Then there is one more neat tool, for those XDS receivers that do not have any front panel user controls (one certain network uses these), called the “XDS discovery tool.” I have found this bit of software to be very helpful from time to time.
