Do a search back into the early 2000's. This is not the first question about the VOX queue priority. Tuned VOX queues with range VOX in the order it makes it into the queue. The difference is who can hear it. My squad's tuned channel gets talked over all the time for the members who are flying in a highly populated range VOX area. With more guys on range blathering at the same time than me or the squadmates in the local area, range voice queue up more volume of playback than my squad's conversation and we get stepped on.
You could always ask HiTech if with the new sound system he will be changing queuing playback priority in favor of tuned channels. Unless he signals a change in that regard. FIFO You guys can always use one of the other private VOX systems. When I've used them your conversations don't get stepped on. But, it can get surreal for squad members who aren't using it.
Years ago I was in an NOE and one of the mission members suddenly started yelling on range, they are popping, they are popping, get in the guns.....the shore was lined with wirbels........Surreal.
