444.225 in Elizabethton is now in service

The newest addition to the NETDA linked system is in service in the City of Elizabethton. 

444.225 is a System Fusion repeater operating in AMS mode. It is linked in analog and stand alone in digital mode. Located at the County Highway Department garage on State Line Road, it provides excellent portable coverage in the city area.

Due to terrain, this repeater is designed to fill certain areas in and around the city and does not have a large footprint outside the city area. Your results may vary depending on your location and equipment.




The W4DOH (441.950) repeater has been moved to the main building on the hospital campus. This has improved coverage from its previous location.

Users are reminded that kerchuncking the repeater IS NOT a valid test of your ability to get into the repeater effectively. A marginal signal may bring the repeater up but your audio may not be adequate  for reliable communications.

If you key up please ID, and state that you are “monitoring” or “testing”




The W4DOH (441.950)repeater at Bristol Regional Hospital in now online. The analog link is being constructed, so at this time the repeater operates as a stand alone site.

Due to the current antenna limitations at the hospital, coverage is reduced in certain areas. Plans to relocate the repeater to the main building are in progress.  More as information becomes available.




NETDA welcomes the WB4IXU repeaters as affiliated digital repeaters. Located in Unicoi County, the 145.180 and 442.900 repeaters are stand alone repeaters servicing the Unicoi/Erwin area.

Information can be found on our NETDA Affiliated Repeater page.




The W4YSF  146.865 repeater is now In Service.

Located in Jonesborough, TN this repeater operates in AMS mode, providing analog and digital communications on 2 meters.

First 2 meter repeater for W4YSF

W4YSF has been coordinated for the use of 146.865 (-.600) to be located in Jonesborough, TN.

The repeater is currently under construction and we hope to enter the online testing phase by 9/20/2020.

This repeater will initially be a stand alone repeater, with possible linking in either analog or digital mode in the future.

Bristol Regional Hospital to get new repeater

In a joint effort with the TN Department of Health, Ballad Health and the Northeast Tennessee Healthcare Preparedness Coalition, approval has been granted to site a new 440 MHz repeater at Bristol Regional Hospital.

This will be a Yaesu DR2-X repeater operating under the W4DOH (TN Dept. of Health) call sign on 441.950 Mhz.

The repeater will be available for normal amateur use but available for emergencies, drills and exercises as needed.

This repeater will provide reliable coverage in the Blountville-Bristol area and be linked into the FusioNet system.  Digital voice linking will be implemented with other FusioNet repeaters as the project moves forward. 



Repeater Information Update

The former KK4FPB repeater in Gray, TN has been re-coordinated to the W4YSF call sign.

Frequency and tone are unaffected by this change. 442.500 + with 118.8 TSQ.

This repeater is undergoing upgrades and moving to a better location for the coverage area we need.

We will keep you posted



Repeater upgrades completed

The 443.100, 443.950 and the 444.750 repeaters are now online with Yaesu DR-2X models.

All functionality remains the same, but the advanced controller in the new repeaters allows for better remote control of each site. These are limited to the system administrators and control operators only. 



Repeater Upgrades Coming

The following NETDA affiliated repeaters will be upgraded to Yaesu DR2-X models:

Jonesborough-443.100 (linked to FusioNet)

Johnson City-443.950 (linked to FusioNet)

The original DR1-X repeaters have been in continuous service since 2016. The new 2-X versions have advanced features that allow for better administration of the system.

Our efforts to continually improve the system are moving forward and we thank all of the users for their support.

The changeout schedule will be posted on our Facebook page as it becomes available.
