One of my hobbies has been Amateur (Ham) Radio for the past 50+ years and those of us that use international morse code have a list of codes so we don't need to spell out everything; maybe that was a precursor to texting and twitter..who knows. QRM means a signal is being interfered with.

Hopefully these forums will be helpful and maybe I'll be able to make some contributions as well as getting answers.
