I'm trying to program a Retevis RB17P for a repeater with only an input tone. When programming through the radio, it asks for the C-CDC and T-CDC, and I'm unsure which one it goes under. When programming with CHIRP, I changed it from TSQL mode to TONE Mode and added the tone of 141.3 hz. When writing to the radio, it throws the tone under the T-CDC. I'm just trying to make sure I have it programmed correctly.
