Ill look at this card over the weekend and get more info.  My mom is somewhat concerned about the situation.  Thanks for the replies.  

I didnt know that I could check call signs.  Like I said, I dont anything about this stuff.

Im not a ham radio operator and know little about it.  However, my father was.  He took several tests and held a higher licsense as I recall.

Here is the problem.  My father passed away in 1996.  The other day my mother received a card from a ham radio operator up in Alaska.  The lady cited my fathers former call letters and said that it was nice talking to him.

I have yet to see this card or letter.  I'll visit my mother this weekend to take a look at it.

It sounds like someone has somehow stolen my fathers former call letters and uses his name.  The person up in Alaska had his address to send the card to my mom.

Has anyone heard of this and what should I do?  Im thinking that I should contact the FCC but I dont know if they regulate amateur radio.
