Does narrowbanding affect CTCSS tones? Here's what I'm getting at. I have a vx 454. Currently our county is still operating under wideband. I updated some things on my radio and went ahead and changed all of my frequencies to narrow, thinking the only consequences would be some coverage loss and minor distortion. I have one channel set up with an MDC1200 identifier. Before switching to narrowband, it would work and transmit the id. After switching, that channel no longer opens up the repeater. Any ideas?
