Hi Jon! sorry not to get back to you sooner with your questions, but here is what is on the go regarding the TCCCS:

Old Equipment TCCCS

ANPRC 521 (small hand held)

ANPRC 77 (manpack) ANPRC 522 (manpack)
RT847/77PRC (veh mount 77) ANVRC 513 (veh installation)

515 HF (manpack) ANPRC 138 (HF manpack)
106 HF (veh) ANVRC 516 (HF veh installation)

PRC 66B (Air Ground Air) ANPRC 113 (manpack AGA)
ANVRC 83 (veh installation AGA)

Now the 522 and the 523 use the frequency hopping technology
when used for secure communications thus replacing the Nestor and Vinson.

Hope that this helps if not just let me know and I will see what else I can dig up in the "ok for general public information category."
