I kinda wished I remember my number from back in '83 as well. The lady at AMA I spoke with when I got back to RC this past year told me they keep records for 10 years and they can look it up for you. Anything past 10yrs they can reassign your old number only if you remember it.

Oh well, at least I got my number from '92.

BTW, does anybody know if AMA assign vanity numbers for a fee? It would be nice if I could use my HAM call sign.
