Recent Technician here. From my travels on the net so far, it seems you may want to also add the following for simplex communication in 70cm:
Discovered via https://www.azfreqcoord.org/bp/bp.htm (PDFs of the bands are on the left menu).
446.0000 Simplex (National Calling, already included in the list)
440.9250 Narrow Band Simplex
441.0250 Simplex
446.0250 Simplex
446.0500 Simplex
446.5000 Simplex
Finding these band plans is really helping me program up my HTs. How goofy will I look hanging out on top of a mountain, surrounded by 6 HTs (*one decent one for Tx and 5 or so more cheap ones for dual watch coverage of multiple channels?) Idk but I kind of want to find out.. .
There are 2m and 1.25m VHF band plans with similar designated simplex frequencies that can be used, plus repeater listings linked to in the upper left of the menu that's worth a look. My guess is that repeaterbook status info is more up-to-date than static PDFs, but they also sort by location and have maps pinned for some bands in the lists.
