Torch came through Bryan/College Station on the way to Houston on May 21, 1996. This is what I and a friend of mine, Sly Kapchinski, found.
154.950 coordination between local police, DPS, etc.
were at least two Georgia State Police in caravan
167.6125 friend heard some scrambled and some in-the-clear traffic
were apparently two FBI units in the caravan
461.5625
464.3625 seems to be main frequency and had unit radio checks. Called "MEDIA 1"
units called "motor #"
464.500
464.625
468.375 sounds distorted
468.4125
468.4625
468.9125
469.4375
469.550
Sorry, this is all I can tell you. Was too busy looking for frequencies in short time I was able to listen that determining the specific use of each frequency was not possible. There are Coca Cola trucks in the caravan as well and it seems like they have the sole permission to ride in the caravan. No other vendors can sell their stuff to the crowds. The other frequencies besides the main 464.3625 were used in conjunction at a park in College Station where some event took place. All the UHF frequencies used DPL code squelch but several DPLs were noted between the different frequencies.
