System Protocol

The NCTC is a linked repeater system spreading across North Texas (and beyond).  It’s very important to key down and wait a second or two before talking.  This allows the entire system to engage and permits all traffic to be heard from one end of the system to the other.  It’s also just as important to allow for pauses in responses while in a QSO to allow timeout timers across the network to reset and allow other stations on the system to break-in if necessary.

When in a QSO try to keep your transmissions brief (if possible) and please use common courtesy in the duration of your QSO. If you are engaged in a lengthy QSO (more than a 10 minutes for example) ask if anyone would like to join your QSO or if anyone else needs to use the system.  Other hams may want/need to use the system and more importantly the system needs to take a breather from time to time.

If you strike up an extended QSO with another local ham on the network, a local 2m repeater or a simplex channel off the network would be a more “system friendly” alternative to consider.

The NCTC system was created several years ago for recreational use, but it is a vital artery for the radio desk at the National Weather Service in Fort Worth to take spotter reports during severe weather events.  NWS Forth Worth (WX5FWD) traffic takes priority over ALL routine/recreational traffic on the network.  When severe weather is anticipated in the North Texas region, all users should be vigilant and keep the system free for severe weather traffic to and from WX5FWD.  The system is equipped with a warning message to alert users to stand by while Skywarn activities are in progress.

The system has a weekly net every Thursday evening at 8:30 pm.  Check-ins are strongly encouraged from all over the system to stress-test the network and ensure the every repeater is working properly.  This is a great time to practice operating skills and get to know others on the system, announcements, for sale items, etc.  Net manager is Mack Avery KJ5MA and he coordinates the net control duties.

After the conclusion of the weekly net, refrain from using the system for 30 minutes to give the system a break.  A hiatus is required for everything to cool down, especially in the warmer months.  Obviously an emergency or a very, very brief QSO is permissible, but any normal (or extended) QSO is strongly discouraged.

Routine status updates on the system and other pertinent content are posted on this web page NCTC.INFO, the “NCTC Radio” Facebook page and discussed on the weekly net on Thursday evening.

In depth discussion of the architecture of the network and site information is somewhat guarded information and probably should be discussed face to face or on the phone – – not over the radio.

The NCTC system is an OPEN system.  All properly licensed hams are welcome to use NCTC system provided they bring pleasant and constructive content to the table.  Any user that violates Part 97 Amateur Rules, demonstrates bad operating practices, inflammatory remarks, etc will be asked to leave the system.  There is no tolerance for this.

The NCTC system blends many platforms in addition to RF to connect sites.  Allstar, WiresX, Echolink and AREDN are a few examples.  As the system grows and embraces these platforms, it’s imperative to regulate access into the system.   We have implemented a Whitelist procedure for access into the network using the above digital platforms.   We simply can’t have unobstructed access into the system, especially if a weather event is in progress for example, and run the risk of having users unwillingly (or otherwise) hamper Skywarn activities.   The NCTC SysOps for these digital platforms are David Houser KG5RDF and David Eaton KB5EDB.

This network is managed by a loosely organized group of like-minded hams that have a common goal of providing a high quality, wide area, friendly and informative radio system.  This is all done without any kind of annual dues.  Contributions are welcome at any time.  At any given time a breakdown in a system component can occur.  Other times a targeted improvement needs to be completed.   Whatever the case may be, we band together, pass the hat and utilize our collective talents to MAKE IT HAPPEN.   Please contact David Stephens KB5WB regarding donations.

In conclusion: Have fun. Be courteous.
