FCC ALLEGES MICHIGAN HAM ENGAGED IN DELIBERATE INTERFERENCE, THREATS
The FCC alleges that a Michigan ham engaged in deliberate interference and broadcasting and threatened other amateurs, and it's sending Michael Guernsey Sr, ND8V, of Parchment a tape recording to back up those assertions. Since late 1998, Guernsey has been the recipient of seven letters from FCC Special Counsel Riley Hollingsworth, including two
warning notices. ......
In a related letter, Hollingsworth issued similar words of caution to
George Zardecki, N9VTB, of Chicago, with whom, he says, Guernsey has squabbled on the air. While Hollingsworth indicated that he would review and take action regarding Zardecki's deliberate interference complaints, he advised Zardecki that "in several instances, your own conduct was as bad or worse than the party about whom you complained." He cautioned Zardecki against retaliatory interference, slander and name calling.
