I know during drills I've done with Paramus PD ESU and other agencies involved, we've never directly used them because our public service system is on UHF (from the PD-stand point) so there is no reason to have V-Tac's set up in separate portables. Although, there have been a few instances where we've drilled with either the NJSP or other local agencies where the NJSP would obviously use I-Tac's and those who would normally operate on VHF would use the V-Tac's unless they were able to get monies for UHF or 800 Mhz radios. By far, the U-Tac's are use most frequent, followed by the 800 Mhz. Outside of drilling, there is not much traffic on the V-Tac frequencies assiged to UASI.
