[AMRadio] Inquiry

[w5jo at brightok.net]

A book has come into my possession that raised some questions that someone 
here may be able to answer.

The book is a 1964 Radio Amateur's Handbook that has some signatures on the 
inner front cover.  The title page does not have a name but is does have 
some calls that, I hope, someone will recognize and be able to tell me who 
held them.

The calls are W4CXA/W5KZA then ex. W0DCA.

If anyone has any information on these calls from 1964 and before I would 
appreciated knowing the holder's name.

Tnx and 73
