Why don't voice radio communications use FM?

Didn't all early radio use AM?

Technically, they were probably digital... Dashes and dots... grin

You're probably right but putting it into writing with dots & dashes
drives me mad!

After learning morse (up to 20 wpm) about 30 years before getting my
PPL it was easy to ident the VOR's. My instructor was very unhappy
that I would not write down the ID in dots & dashes. Claimed the
iexaminor would not like it. He couldn't believe I found it difficult
to understand morse written as you've done above. Just for fun I tried
to decode your characters, took me a 2-3 minutes to make sense of it.
Much easier to understand as a sequence of musincal type tones :-)

I'll admit I cheated a little. Go to
http://www.onlineconversion.com/morse_code.htm and you can paste the
dots and dashes in and get a english translation. Works the other way
too.
