The 146.940 MHz and 444.300 MHz repeaters are dedicated to the memory of their founder:

George W. Shaver, K4HXD, 1943-1995

OPERATIONAL STATUS:  ON THE AIR!!
PLEASE NOTE: THE 146.940 REPEATER MAY OR MAY NOT HAVE  A 118.8 Hz DECODE TONE ACTIVE. IF YOU ARE UNABLE TO ACCESS THE REPEATER, PLEASE VERIFY THAT YOU ARE TRANSMITTING A 118.8 Hz  TONE. IF THE REPEATER HAS THE TONE DECODE ACTIVE, IT WILL BE RETURNED TO CARRIER SQUELCH AS SOON AS POSSIBLE.  73 de Tim WB4GBI

For 50 years, one of the most widely used 2-meter repeaters in the East Tennessee area is the

146.940 (-) repeater, located on 
Bluff Mountain, also known as "Greentop," just outside Pigeon Forge, Tennessee.

 From Tim, WB4GBI: " For those of you who are recent additions to our great hobby, you might not know that the 146.94 repeater was the very first 2-meter repeater in East Tennessee. Its history is that of great and continuous service. I am VERY proud to be carrying on the tradition started by George, K4HXD, who was the creator and founder of this repeater. We lost George in 1995. He was of my mentors." 
 
The 146.940 repeater is the 
oldest "continuous service" 2-Meter Amateur Radio Repeater 
currently on the air in East Tennessee, and celebrates its 50th Anniversary in 2017! 

In addition to our in-depth investigation into the history of this machine... we have uncovered a few tidbits of this history.  You can see the fruits of this effort on the newly created HISTORY PAGE of the 146.940 Repeater!

          The 146.940 Repeater, located on Bluff Mountain (Green Top) in Sevier County

     This wide coverage repeater is located on the same tower as the commercial FM station WIVK, 107.7 FM.  This radio station, licensed to Knoxville TN,  has a very wide coverage area, which encompasses the majority of Eastern Tennessee, from Bristol to Chattanooga.  So, if you can hear this frequency on your regular FM Broadcast radio, you can most likely also hear this repeater!

     As everyone knows, it isn't how far a repeater can transmit a signal that makes it a good repeater... it's how well it can copy a low power station, to repeat it's signal that makes it a great machine!

     In the photo to the right, you will see that the '.940 machine's antenna shares the tower structure with many other primary service antennas, including public safety systems, commercial repeater systems, and of course, the 7-bay  FM antenna of the radio station take up the very top of the tower. The .94 repeater is in the tapered red section of the tower

Many thanks to WIVK for their use of this facility!

WIVK-FM tower, home of WB4GBI 146.94 
     In addition to the coverage benefits of being co-located with it's "Tower-neighbors"... this repeater site also has many other benefits as well.  Since WIVK is the primary EAS Station in east Tennessee... there is ample emergency power for use during power failures, for whatever reason.  This makes the 146.940 machine a very important part of the emergency communications infrastructure, regarding amateur radio. 

     This repeater is the primary relay for SKYWARN in east Tennessee, where weather spotters can contact the National Weather Service, directly, during inclement weather, to officially log in unusual weather observations.  It is also used as the primary repeater for METERS, an EMCOMM group serving the Middle East Tennessee area. It is also used by other groups for emergency communications, due to it's wide coverage area, and it's reliability!
 

      EQUIPMENT LIST FOR THE 146.940 REPEATER: 

  • Motorola MTR-2000 100 watt VHF commercial-grade repeater (Thanks to Todd, KA4OAK, for making this equipment possible!) 
  • CAT-200 repeater controller
  • Phelps Dodge (now Celwave) six cavity duplexer 
  • UHF Motorola CDM 300  UHF control receiver 
  • 7/8 foam heliax from duplexer to antenna
  • Commander Technologies (formerly Phelps Dodge/Celwave) "Stationmaster" antenna  (@ approx. 265 feet up the 330 ft tower) - Newly installed in 2012

This repeater combination was placed in service in February 2014.  It replaced a Motorola "Micor" repeater  which George, K4HXD, had constructed in the 1980's.  The Micor repeater is being refurbished, and may return to the air again soon!

The 146.94 repeater celebrates its 50th Anniversary of service in 2017!
A brief history of 146.940...
     The 146.940 repeater is the oldest and original repeater on the air in the Middle-East  Tennessee area.  After consulting several long-time amateur radio operators, and compiling information about this repeater's history,  it has been determined realization that the 94 machine went on the air in 1967. George Shaver, K4HXD, placed it on the air at a State of Tennessee tower site on top of Chilhowee Mountain in Blount County. It remained on the same mountain top (moving to an adjacent tower site) site until George sold the repeater to Tim Berry WB4GBI in 1985. Tim moved the repeater to the now-146.625 site in 1986 where it remained there until 1998 when it moved to its present home at the WIVK-FM transmitter site. Incidentally... Tim's first experience with 146.940 repeater was accompanying George on a repeater maintenance trip... that was waaaay back when Tim was only 16 years old!

Tim and the 94 repeater

This repeater location is probably one of the best sites in all of Eastern Tennessee, as you can almost see every inch of the Tennessee Valley - which makes up the majority of the eastern third of the state. 
The footprint of this repeater is absolutely unbelievable, as folks have been known to converse with hams all the way from Virginia, Kentucky - and in some cases parts of northern Georgia - all from this machine!!

Below, is a view from near the repeater site, looking back toward Knoxville....               Below, is a postcard from around 1915 that shows Bluff Mountain (Greentop)
(Notice the Seymour community in the lower-right... with the city of Knoxville in the Distance)           Thanks to Todd, KA4OAK, for the use of the postcard!!

The 444.300 machine is a combination of Motorola Micor and General Electric (GE) MASTR II equipment, and a  Vocom products commercial grade 100 watt continuous duty power amplifier  (PA). 
 
In the photo on the LEFT,  you can see a close-up view of the 444.300 machine.  The receiver is mounted at the bottom of the rack-mounted equipment, then a home brew control panel similar to a General Electric KC-19 control panel  is just below the receiver. Above the receiver and its power supply, is the 449.300 exciter (100 milliwatts). The Vocom 100 watt continuous duty PA and the six cavity Phelp-Dodge (now Celwave) six cavity duplexer are at the top of the cabinet. 
Meanwhile, the photo on the RIGHT depicts the bottom of the Rack cabinet, containing the the 50 AMP homebrew power supply, which was built by Bill Nobles from Kingsport, TN. 
 In case you're interested, here's a photo of the "other" transmitter in the building...the 40KW  Harris transmitter for WIVK-FM

From Tim, WB4GBI: 

For those of you who have one of the Motorola MCS2000 radios that were purchased in the Knoxville area recently, you can find my 900 Mhz repeater frequency by selecting "ATL 0625"  in the first zone of programming. There is a repeater in downtown Atlanta that is on this same frequency and PL tone. I picked this frequency and tone combination on purpose, as it is already in the MCS2000 radios that I have programmed. This is one channel above the "NFARL" channel that Kevin's (W4KEV) repeater is on. Or, you can contact me and I will make arrangements to re-program your radio for you.  

This repeater was purchased from a Ham Operator in Northern Ohio, 
and just recently made the trip from just south of 
the great lakes area, to East Tennessee!
This machine also features a tone-squelch access of 151.4
as all 900 Mhz repeaters are tone-squelch machines.

This repeater is a Motorola quantar machine, 
with the internal high stability oscillator.
It has been installed on the same tower as the 
146.940 and 444.300... along with 
commercial radio station WIVK-FM 107.7! 

The duplexer on this machine is a 2 cavity decibel products unit, 
and the machine delivers 80 watts out of the duplexer to the antenna.
The antenna, by the way, is installed at about 120 feet up the tower, and was a leftover gift from a paging company 
when they moved to a different location.

This machine was placed into service on Tuesday, March 8th 2011,
and is currently available to all licensed amateur radio operators
who have the proper equipment.

Enjoy!
