|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

A brief history of 146.625...
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.
