The “North Central Texas Connection (NCTC), is a continuing work in progress. Without you, the donors, our technical staff and the various repeater owners and trustees, this system could never exist.

Most of the system is interconnected either by (420 Mhz.) full duplex links or NXU’s (Internet Extension Units Wires, Allstar, and EchoLink”).

Our primary objective is to provide a backup system for the National Weather Service and their weather spotters during times of inclement weather. Please Read: “System Protocol”.

The secondary purpose is to provide for you the Amateur Radio Operator a way to communicate in the Dallas/ Ft.Worth metro area and the surrounding cities providing for technical talk and typical idle time chat.

Numerous long hours, weekends, donations of equipment and funding have allowed us to create this project. We hope you enjoy the system as much as we have enjoyed taking old equipment and giving it a new purpose. We look forward to hearing from you, and hope you enjoy this valuable resource.

Helpful information for Allstar Users

Helpful information for Allstar Users. This corrects issues that occurred during the Hurricane. Turn off DNS on private nodes:

There are three options for node lookup. The default if not defined isNS. If you strictly want local then set it to local BUT in the very near future hamvoip users will be able to define private node groups and set IPaddresses for those nodes in the hamvoip registration system. When this happens and if you want to do it you would need to set the value to =dns Also if you are using dns or local lookup you will want to run the filelookup_onoff.sh script to turn off (disable) the file lookup system asit is not used. To test what method is currently being used for aparticular node use the rpt lookup command in the client.

Here is the text for setting –

; There are three choices for the way to
; nodes. Being able to lookup nodes and
; to an IP address and port is a requirement
; for proper operation of Allstar.

; NOTE – when using DNS lookup on all nodes
; a server the filelookup_onoff.sh script
; be used to turn off redundant flat file
; DNS lookup is the default.

; node_lookup_method=dns (Default)
; Uses hamvoip DNS lookup

; node_lookup_method=file
; Uses Allstar flat file lookup
; Deprecated in hamvoip v1.5

; node_lookup_method=local
; Uses local fixed routing defined in the
; [nodes] stanza below

Courtesy Tones

Just some good information for the users of 443.200. There are a group of low level courtesy tones incorporated as diagnostic tools. If you’re local currently there is no tone. If you hear two quick beeps the source is from East of Aledo. Should you hear 3 quick beeps the source is from the West of Aledo. Last if you hear 4 beeps the source is from up North. Oh I spilled some beans…No 4th port quite yet, but in the making. During the little service call, some extra functionality was implemented. We can measure the temperatures in cabinet and PA temps remotely and act accordingly if needed. We also have winter cabinet fan control now. Stay tuned my friends!



In the Lab today. Brazos to Caddo RF Link package almost complete. This will be a low power full duplex link to allow 4 wire com & control further down the path of radios.

ETECS System

The ETECS system in East Texas is dialed into our network via Allstar today. It’s a system of about six repeaters surrounding Tyler (W5ETX).

Just kicking the tires to see how it plays, so feel free to cross-pollinate…

Net Control

The LAARK Contesting and Public Service net will take place the last Sunday of May, May 27, 2018, at 2000L. This net originates on the LAARK 220 repeater 224.00 with a standard offset and PL tone of 110.9. This repeater is also linked to the Rosston 220 repeater (KE5GDB) and the 220 repeater on Stark Hall (AF5RS).

Please forward to me any Public Service events your club will be participating in for June and the following months, and invite all your members to join this net.

The topic for this month’s net will be “Contest Logging Software.”
