I got my amateur license back in the early '80s, primarily for putting it on my resume for an electronics job. Never used it outside of developing my Morse code speed, and once I got my Advanced Class and short call sign, I never used it again.
Well I'm retired now, and I plan on traveling the US while living long-term in an Airstream RV. Are there any constraints or gotchas I should be aware of when it comes to having no fixed address for years at a time?
