Skipp;
The specific controller he is using and was asking about is
a Comm Spec ( TP3200 as I recall ) commercial repeater controller.
My comments were directed towards commercial not amateur
controllers...Commercial repeater controllers designed for multi-tone
community repeater applications etc...do in fact by necessity need to
strip and re-insert tones.. but your comment is quite true on the
average low/lower end amateur controller, most do not have sufficient
filtering to completely remove ctcss and a portion sneaks through
anyhow.. unless you add your own filter aka ts-64 as you point out...
