Here is a list of all sorts of frequencies for those who are interested (67-page pdf file)
Unfortunately it only gives the frequencies so there will be a learning curve for those wishing to program them into an HT.

I know a lot of people will not click on that but I saved it. Has everything from fast food restaurants to NASA.
It would be a great exercize here, I think, to compile a list of SHTF frequencies.
