not so much technical as tactical. Are scanners used to monitor what other teams transmit over their radio, or for some other reasons (like listening to track crew or officials for heads up on things maybe not broadcast on the FM radio feed, or if they don't even have an FM feed)?? Is it a common but usually unspoken about thing? Of course PM if that's the case lol. I ask because i'm looking for a new headset and wondering if its worth getting a headset with a scanner port in addition to the regular radio port.
