Super RARE elusive I Call! Rarely used on IDPS S1, S3.. Is this S2?
Individual Calls,.. or I Calls are radio to radio private calls that are ONLY heard on the 2 radios using them. They do tie up freqs on the system just like an Group Call (Talkgroup)... As busy as S1 is ,... It would have to be an extreme good reason to use one. (Most users on S1 are pretty much told never do it.)
