How TCC works.

Small blocks denote daily station functions, stations A and L being the only ones that report into an area net other than their own. Note that traffic from east to west goes into area nets while traffic from west to east may go into section or region nets to save time.


How TCC works
(Click on the image for a clearer picture)

 The purpose of the Transcontinental Corps (TCC) is to relay traffic from one NTS area to another, conducting liaison with NTS nets to do so. Each NTS cycle has specific functionaries under the supervision of a TCC director.

The function of the TCC director is to assign functions, centralize, coordinate and supervise these activities and file status reports each month with ARRL Headquarters. There are six TCC directors, two for each area.

TCC functions are performed in several ways, according to circumstances. In many cases, the method used is an out-of-net schedule between TCC counterparts of different areas to effect the exchange of traffic from one area to another.

Times and frequencies of the schedules are worked out by the TCC directors working together and are arranged in accordance with time available, propagation conditions, stations available and other factors, always with the objective of the best service possible on an organized, systematic basis.

TCC stations must have the following qualifications:

  1. Adequate signal power and appropriate mode to perform the job to be done.
  2. The highest caliber of operating ability and NTS net savvy.
  3. Capability (both operator and equipment) to keep the required schedules.

Station Functions

A TCC station might perform only one TCC function per week. On other days of the week, other stations perform the same function. TCC operates on a seven-day-per-week basis. Each function consists of two steps, as follows (all times in UTC):

Station A

  1. Normally located in the Eastern Area, this station reports into Eastern Area Net at 0130, receives all traffic for the Central Area.
  2. Reports into Central Area Net (CAN) the same night at 0230, distributes the traffic upon direction of the CAN control station.

Station B

  1. Normally located in the Eastern Area, this station reports into Eastern Area Net (EAN) at 0130, receives all traffic for the Pacific Area.
  2. Keeps a schedule with Station H some time between 0230 and 0430 and sends this traffic to him/her.

Station C

  1. Normally located in the Central Area, reports into Central Area Net (CAN) at 0230, takes all traffic for the Eastern Area.
  2. Keeps a schedule with Station K some time after 0330 and sends this traffic to him/her.

Station D

  1. Normally located in the Eastern Area, this station keeps a schedule with Station J some time between 0530 and 1930 to receive traffic for the Eastern Area.
  2. Sends this traffic into destination Local, Section, Region or Eastern Area Nets at first opportunity.

Station E

  1. Normally located in the Central Area, this station reports into Central Area Net (CAN) at 0230, receives all traffic for the Pacific Area.
  2. Keeps a schedule with Station G between 0330 and 0430 and sends this traffic to him/her.

Station F

  1. Normally located in the Central Area, this station keeps a schedule with Station I between 0530 and 2030 to receive traffic for the Central Area.
  2. Sends this traffic into destination Local, Section, Region or Central Area Nets as soon as possible after received.
