Hey, In short, I don't know the range I can access. I am prompted to select a 2-digit channel. That's all I can choose. I don't know how that corresponds to Mhz but, after I choose a channel, then a MHz reads out on the display. Each time I did this, it ended up assigning a frequency lower 561.350 MHz.
