I just got my call sign and bought a gm30 Radioddity but when I first, tried to program on a regular repeater channel and just adding the tones and then second, tried the same thing but on a new diy channel…..but neither worked to get the repeater to beep back. It seemed pretty straightforward so I’m confused. It wouldn’t let me put an offset and I thought maybe it was dcs and not ctcss but it wouldn’t let me do that either. Btw. I’m programming by hand. Thank you
