NDB "BO - 221.0 kHz", BRISTOL, TN, USA:
BO 221.0 kHz
This NDB is surrounded by gently rolling pasture land dedicated to cattle grazing. The site is located at the end of a gravel road off Delmer Salts Road, about 10 miles northwest of Johnson City, TN. The twin towers, separated by 300 feet, support a single-wire T-antenna 30 feet above the ground.

BO 221.0 kHz
The radio shack and 75 MHz twin Yagi outer marker are offset about 15 feet from the center of the single wire T-antenna.

BO 221.0 kHz
The wire leading from the upper left corner of the shack in this view leads to a post and whence up to the center of the horizontal wire. The pole in the foreground supports the 75 MHz Yagi.

BO 221.0 kHz
The north support pole.

BO 221.0 kHz
The south support pole.

NDB "DYQ - 263.0 kHz", GREENVILLE, TN, USA:
DYQ 263.0 kHz
Accessed via an badly eroded dirt road at the end of a private driveway off Kathy Ave in Greenville, TN, this NDB is 300 yards from the main road atop a knoll at an elevation of about 100 feet above the surrounding countryside. The structure is tucked away among the trees seen in this picture and does not become visible until almost upon it.

DYQ 263.0 kHz
This NDB is a symmetrical two-wire T strung between a pair of telephone poles separated by 300 feet. The south pole shown would be difficult to discern among the trees in this view were it not for the crossbar at about 30 feet elevation.

DYQ 263.0 kHz
Standard Southern Avionics' transmitter and coupler boxes.

DYQ 263.0 kHz
North pole. Note the holes running up the length of the pole. Initially these were thought to be woodpecker holes but closer examination (next pic) showed that the holes were only about an inch or so deep.

DYQ 263.0 kHz
Another view of the many holes in the north pole. Note cracks running the length of the pole, perhaps where branches formerly grew out. Speculate that the holes were dug by birds foraging for insects in this crack. Seemingly the pole remains structurally sound.


NDB "RVN - 329.0 kHz", ROGERSVILLE, TN, USA:
RVN 329.0 kHz
RVN is located on the grounds of the Hawkins County Airport, approximately two miles southwest of Surgoinsville, TN. Rogersville, TN is a further eight miles to the southwest from the beacon.

RVN 329.0 kHz
Radio Shack located in an open region to the rear of the airport buildings.

RVN 329.0 kHz
View of the forty foot telephone pole supporting the east end of a two-wire symmetrical T antenna.

RVN 329.0 kHz
The west end supporting pole about 300 feet distant from the east pole.

RVN 329.0 kHz
Connection to the two-wire system is made directly above the radio shack.

RVN 329.0 kHz
The Southern Avionics transmitter, Model SA 50, described as state-of-the-art (June 2013) by the airport director who kindly permitted access to the shack to my permit picture taking.

RVN 329.0 kHz
Closeup view of control panel of the FCC ID 69 SA50 radio beacon transmitter.

RVN 329.0 kHz
Backup emergency power supply.

RVN 329.0 kHz
Control panel of the backup power showing the main circuit breakers which occasionally kicks out for some unknown reason, a malady reported at another airport that I have visited.

RVN 329.0 kHz
A retired airplane power plant and airframe mechanic as well as a pilot working on his private plane. He kindly shared about an hour of his time to provide me with a of great deal of information, lore, and problems concerning navigational beacons.


NDB "JXT - 346.0 kHz", MORRISTOWN, TN, USA:
JXT 346.0 kHz
JXT 346 is located at the corner of Hicks Rd and Night Rd, in Jefferson City, TN, approximately eleven miles to the southwest of Morristown, TN.

JXT 346.0 kHz
A six spoke top hat with additional capacity provided by the upper guy wires.

JXT 346.0 kHz
Rear view of radio shack.

JXT 346.0 kHz
Another view of the rear of the radio shack.

JXT 346.0 kHz
Although the base plate is severely corroded, seemingly the security fencing, associated hardware, and warning signs have recently been replaced (see next pic).
