? 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.
