Welcome to the Lone Star State and the web home of the North TeXas Repeater Association.  NTXRA is comprised primarily of amateur radio operators employed in the telecommunications and IT fields in the Dallas area. We have constructed a network of repeater stations in and around the region to provide clear, reliable communications.  We continue to enjoy our association with the Internet Radio Linking Project (IRLP) to expand our reach throughout the world.  We invite all licensed radio amateurs to stop by and give our system a try.  On the local front, we support all public service operations.

Latest News

The “flame” continues to work well on VHF and UHF.  The 145.35 is working better than ever after the antenna system was fixed.  The new PA helped a lot but the most difference came from a new Kenwood repeater.  The same antenna fix helped the UHF system in McKinney.  The site still doesn’t provide the coverage we expected but it’s greatly improved. 

The new 900 project is growing.  As of March 2014 we have two 900 repeaters on the air, one in Dallas on 927.0625 and one in Mc Kinney on 927.1625.  They are linked together and connected to 444.650.  Stop by and check in.  The 900 has more traffic than the UHF system!  Soon we will have a link to Howe, Denton and Ft. Worth. 

If you are going to Dayton in 2014, give us a shout on 442.025+, PL 127.3.  Our portable repeater provides good coverage from the Airport to the Arena and as far south as Miamisburg. 

 

 

Brief History

The initial system was constructed in 1999 on a building site in Plano, TX operating on UHF.  As the repeater traffic increased, the need for wider coverage became apparent and a search for a suitable site began.  In early 2000 a site was secured west of McKinney, TX, 35 miles north of Dallas and the system was moved.  The new site has a split antenna system, receive at 809' AGL and transmit at 750' AGL.  This site became the anchor for the NTXRA network.  Good mobile coverage reached over 60 miles in all directions.  

Shortly after the McKinney site was completed, a second was added in downtown Dallas.  The Dallas site provides good mobile coverage to the east, south and west of Dallas.  Additionally, excellent portable coverage was gained in the major sporting and entertainment venues in the Metroplex. Good mobile coverage is available from the Texas/Oklahoma border to about 50 miles south of Dallas, West Ft. Worth to 75 miles east of Dallas.

At the beginning of 2001 discussions with a few amateurs in the Atlanta, GA area uncovered a desire to have a long distance link to join two repeater networks of telecommunications concentric groups.  After several ideas were investigated, the IRLP system showed most interesting.  Not only would IRLP give both systems the ability to join, it would allow the systems to experience real DX through the IRLP network.  By mid 2001 the IRLP hardware had been installed and a link established.  IRLP was developed by VE7LTD and the system currently covers most Canadian provinces, Hawaii, Alaska, Great Britain, Germany, Australia, The Caribbean and many states throughout the contiguous United States with new nodes coming on-line almost daily.  To find out more on IRLP, click here.  To see a listing of all active IRLP nodes click here.  If you are already connected to the IRLP system, try our Reflector at Node Number 945x.  Our local node is 3695 on UHF.  Repeater network commands and operation guidelines can be found here.
