Depending on which set of instructions one chooses to follow, some say have them both on the same channel while others say have them on different. I had the base and the repeater on different channels, one 11 and the other 6. That was just fine for the three days everything was cool, until today of course. Now I have them both on the same, channel 11, and everything for now is copacetic. What the hell?! Does this mean in another couple of days I'll have to change it back or to something different or just throw them both out the window?
