Reply To: Install and Using CTCSS board WB6FRZ March 24, 2014 at 5:20 PM #9884 Hi Scott, Yes, I have purchased and installed a few CTCSS boards from Communications Specialists over the years into different radios. They have all worked beautifully. Good company. I’ll give you a call and we can talk. Very 73, John WB6FRZ Settings
