Morse code useful

It can be extremely useful. Especially in difficult signal conditions.

Morse code does not have to be used with Amateur radio only. You can uses flashlights, buzzers, bells, pretty much anything that will trigger one of the human senses, in order to learn and practice the code to get the right series of dits and dahs for each letter, number, mark, and other key elements of information that can be transmitted using timed short/long impulses of just about any type.

As for radio communication using Morse code, Only commercial organizations and amateurs use it on a regular basis. But as far as I know (and I could be wrong about this) keying a radio in one of the non-licensed services (FRS/MURS/CB) in a Morse Code pattern is legal. It will get you chased off the radio most of the time if you do it on any of the CB channels that anyone within about a hundred miles uses. And I am talking about keying the mike, to transmit the actual legal mode, be it AM, FM, SSB, or whatever. Not actually modifying a radio to send a simple carrier in a morse code pattern using a key.

Just my opinion.
