Only a few jurisdictions make taping your own conversation illegal. Illinois is one, and the state where Linda Tripp made recordings (Maryland?) is the other.
This is as opposed to surreptitious recordings of conversations of which you are not a party - that is clearly "eavesdropping" when the conversation is not otherwise public.
In the Linda Tripp case, that jurisdiction made it a felony to record one's own conversation - imputing a (fictional, in my opinion) right to privacy in what one person tells another, enforceable against the authorized "tellee" (!), and only with respect to one medium (audible recordings). If Linda Tripp had only hired a transcriptionist to make a written record of the conversation, or dicated it from memory later on, and published it in a magazine article, she would have been fine.
