€  As I understand it, the vhf suppressor has not been improved because 
the designer is convinced that there has never been a case of one that 
oscillated.  //  See Figure 15 on my Web site. 
.  If you are using AL80 with a modern radio, high speed switching would 
be nice.  This will cost around $60 --  if you know how to solder.

-  good luck, Chris
