For those who may not know, Al Huebner was the long time host
of a show called "The Health Department" on KPFK. It mainly dealt 
with information on alternative health care and new health research.
He presented among, other things, material from obscure, scientific
journals, for example of the benefits of Vitamin E. 

Al Huebner was taken off the air for violating the gag rule. I will
let him speak in his own words in his letter to the LA Weekly,
March 31, 1995:

Dear Editor:

In saying that I took myself off the air, acting general manager Pam 
Burton is correct only in the sense that I knowingly commented on
developments at the station in the face of a gag order imposed on
programmers at "Free Speech Radio" Station KPFK.

During more than 21 years of broadcasting at the station, I had often 
responsibly commented on policy, fundraising efforts and programming.
Some previous members of management encouraged those
comments, some bristled at them, but none invoked a gag 
order.

More important, my 4 minute commentary on February 10 went to
the matters of deceptions by the station's new management----
it was chiefly, but not exclusively, listeners who were deceived---
and of authoritarian rule by KPFK's absentee owner, the Pacifica 
Foundation. There has still been no response to these comments.

As long as the new management can keep critics away from
 listeners, I think it's content to hope that the outrage will blow
over and to base the station's future on "anti-Newtism." The 
tactic may work in keeping KPFK alive, but at what price to the 
concepts of free speech and progressive politics that the 
station purports to serve?-----Al Huebner
