The National Weather Service office in Morristown, Tennessee (KMRX) is the facility that issues all warnings for severe weather in the area.  Besides East Tennessee, KMRX also serves Southwest Virginia, Extreme Western North Carolina, and Extreme Northern Georgia.

The dome-shaped object in the above image houses the Doppler Radar used by the National Weather Service.

This is the Amateur Radio Station WX4MRX manned by amateur radio volunteers who have been authorized to be there by the National Weather Service.

Along with a computer with internet access (foreground), a packet radio station (background) is also used to pass weather information to amateurs using APRS. Underneath the monitor are 4 different amateur radios, two of which are dual band (2m/440) and one that is capable of transmitting on the 220 MHz band.

On the window in the background is a Weather Radio with SAME capability.  The National Weather Service will sometimes use this radio to test their signal being transmitted from one of 3 transmitters in the area in case they receive reports of a transmitter malfunctioning.  Also, they can verify that their SAME codes are being properly issued by monitoring its output display.

Tucked underneath one of the radios is an ARRL amateur radio repeater directory, so that they can find repeaters for airing weather bulletins on.

The yellow paper atop the monitor in the foreground reads:  "THIS IS WX4MRX SKYWARN STATION MORRISTOWN, TN".

The station in in the corner of the main weather facility opposite the meteorologists' radar console.  It is close enough for the volunteer(s) to have quick access to a meteorologist while at the same time being far enough away to not interfere with their work, both by presence and by noise.

The antennas are outside on a tower and are installed according to NOAA and federal government guidelines, which are more stringent that normal guidelines for amateur radio tower construction.
