I know the primary answer to the question is going to be different for every location. What I am asking is, have you as an experienced ham, come across an absolute must have frequency that you have discovered and want to share. I know being here in NW Iowa I won't be able to get your primary channel up there in the PNW or hit that NYC repeater chat. But what have you discovered in your travels and elder knowledge to be a must have in a radio. Mind you I do have the National 70cm and 2m call channels programed. But I am sure I have overlooked something. I have also added Local repeaters, slightly further repeaters, The ISS, Local Dispatch frequencies to monitor, 90+ mile repeaters, and the national storm chase freq, and some odd ball frequencies that I utilize. Just kind of looking for those gems now.
