quick = 1 will give you a nice channel hopping click when talking on Uniform
uhfVol = 6
vhfVol = 6 will give IVC volume a slight boost over default
selfblock = 1 will give you a really irritating tone when two players are talking at once. Not realistic, but certainly helps in a multiplayer environment where comm discipline might not be great.
Everything else isn’t really needed (personal opinion)
