"§97.403 Safety of life and protection of property.
No provision of these rules prevents the use by an amateur station of any means of radiocommunication at its disposal to provide essential communication needs in connection with the immediate safety of human life and immediate protection of property when normal communication systems are not available."
I think where the confusion arises is the phrase "No provision of these rules…"
The interpretation of "these rules" seems to be the issue.
These rules seems to apply to the Part 97 rules only. If you think this applies to other rule parts, then read this:
§2.405 Operation during emergency.
The licensee of any station (except amateur, standard broadcast, FM broadcast, noncommercial educational FM broadcast, or television broadcast) may, during a period of emergency in which normal communication facilities are disrupted as a result of hurricane, flood, earthquake, or similar disaster, utilize such station for emergency communication service in communicating in a manner other than that specified in the instrument of authorization
"EXCEPT AMATEUR".
Amateur operators are governed under the Part 97 rules. Part 97 rules say that in emergencies "no provision of THESE RULES…"
2.405 says the rule that allows operation in an emergency specifically does NOT apply to amateurs.
There is NOTHING in Part 90 that gives amateurs the privileges to operate on those frequencies.
There is also NOTHING in Part 97 that gives amateurs permission to operate under any other rule parts.
Claims that this single rule in Part 97 gives access to any/all spectrum for use in a real or perceived emergency is taking a -whole-lot-of- liberties with the meaning, and completely ignoring 2.405.
Amateur radio operators should read and fully understand all the rules that apply to them. That includes Part 2, Part 15 and Part 97.
Seems pretty clear and unambiguous to me. It's well documented, so I'd suggest planning ahead and not expecting a perceived loop hole in the laws to cover you. Today is Saturday, and we do seem to have a lot of time to spend on the internet. I'd recommend researching a PLB and purchasing one. It is the right tool for the job and is perfectly legal to use.
