My Minitor VI is recieving 154.16 tones and voice dispatch audio as of Wed 1742 hrs. Last nite I was on duty and it wS functioning fine as well. I have heard of nothing indicating 154.16 will be altered in any way. As to 153.950, this is my opinion, may be replaced by 150.995. As I had stated a few months ago 153.950 has an ongoing conflict with some companies in Virginia and they have been looking to get another frequency to get that monkey off their back.
Again, just my opinion based on the new VHF lineup added to the P16 database. I find it interesting 153.950 is showing removed from the list and that new Freq 150.995 has been added as an OPS channel is why I say this. But I never want to be a bad source of info !!
