FYI, the CSS frequency is the only one of those that is actually a simplex frequency in the Southern California band plan (Torrey is a business band USHPA frequency).
You are likely to have interference from and interfere with repeater operation on the 144.9xx frequencies and you may interfere with operators on 144.120 without ever knowing it, since it is designated for AM, SSB & other weak signal/narrow bandwidth modes.
Adherence it the band plan is not legally required, but is respectful of other amateur radio operators. A license is required to use any of these frequencies.
