Field Communications is supposed to be the direct communication from the on scene command to Fire Alarm. It is used on every single box assignment.What is the purpose of "Field Communications" and "Command" talkgroups? How are they used in practice?
Also, does AACo use VRS's like DC and Montgomery Counties? If so, what units are they in?
Following up, if the incident commander is on the field comm talkgroup, how does he/she monitor the tac channel? Does he/she have to monitor 2 radios? An assistant with another radio (tuned to the TAC channel?)
The VRS in Montgomery and DC have obvious extra antennae attached to the host vehicle - I haven't noticed the same stuff here in AACo. Interesting.
Anytime there are 3 or more units on a call, on of the units is required the take "command" and "field communications". Battalion Chiefs have the luxury of two radios so they can monitor both "fieldCom" (Delta for Echo or Foxtrot or Juliet for Kilo or Lima) and the fireground talkgroup. For lesser incidents, the units just have to make due. This is done for several reasons -- one - to ensure multiple units aren't calling in to fire alarm and second - because fire alarm generally only monitor the fieldcom talkgroups (particularly when they get really busy).Here is a picture of BC 2's car that I took. It has two base radios in the back with a command post. The BC would also have another radio on their belt.
