The 146.625 (-) (optional tone: 118.8 Hz) repeater is located on Chilhowee Mountain in Blount County, TN.  near a community known as the "Top of the World".  This is a very beautiful place in east Tennessee... but just as you might imagine, it is in a very rugged area, where access to this area is not very easy.  The troubles are worth it though... as the high elevation of the terrain makes for a perfect Repeater site!
 

 
The image above left is the actual cabinet with the repeater installed. The duplexer is at the bottom, and the repeater power supply is just above the duplexer. The repeater itself is above the power supply, and the Motorola "Maxtrac" control receiver and control decoder is at the top of the cabinet just below the meters. 
 
 
 

     This photo is of the repeater rear. The 100 watt power amplifier heat sink is visible below the back panel. Above the back panel is the UHF remote control receiver and the DTMF decoder for remote control.  
 
 

There are several other commercial and amateur service repeaters located at this site.

As indicated by the red lamp on the GE meter bridge, It's on the air!



 This repeater is another of many relay repeaters for SKYWARN, where weather spotters can contact the National Weather Service, directly, during inclement weather, to officially log in weather observations.  It is also used by many other amateur groups for emergency communications, nets and general club uses.
 

     A brief history of 146.625...
    This machine utilizes a Factory-Stock 132-150Mhz GE Mastr II Repeater combo... which was acquired back in 1982. This repeater station was originally on 145.47.  It went on the air as 146.625 in 1988, on Sharp's Ridge in North Knoxville.  Later, it was moved to Chilhowee Mountain (the original 146.940 site).  It remained there until that site was abandoned in 2004.  This forced the repeater's move to it's present location near the Top of the World Community in Blount County. A new antenna and feed line was installed on October 28th, 2014.  The duplexer was upgraded to a Celwave (formerly Phelps-Dodge)  PD-497-1 in June 2019. 

EQUIPMENT LIST FOR THE 146.625 REPEATER:

The 146.625 repeater now has full emergency power! As of July 2017, a new 8 KW generator with a 250 gallon propane tank has been installed at the repeater site and is fully operational! Based on fuel capacity and consumption, there is enough fuel to completely power the site for several days. This insures the repeaters will be available for users and emcomm/auxcomm groups throughout any event that is needed. Equipment has also been installed to notify in the event of a power failure.
