Certainly not all NWR transmitter sites are the same. Almost all transmitters are dual-transmitter systems. Not all sites have air conditioning, while others operate in a narrow range of temperatures.
Most sites use special telephone circuits as their audio communications link.
The quicker this can be accomplished the more efficiently the national maintenance contractors tasked with performing the repairs can be notified. The NWS goal is to minimize the off-air time and to accomplish this, we must be aware of the service status of every transmitter site in the Southern Region NWR network, which is around 160 sites. The first function is to detect and report several defined malfunctions associated with the transmitter site and its equipment. The second function is to respond to incoming telephone calls and report or execute user-selected commands. No other special equipment is required.
