WRUU you are right, the frequency (462.5625) I was trying to input was different than the factory-programmed frequency for the DIY channel I selected. In the case of trying to set up this particular channel I tried doing the programming on the radio by putting it into frequency mode, inputting the frequency, ctcss, etc.. deleting channel 31 or whatever I selected using the DEL-CH menu option (Menu no. 28) and then storing it using MEM-CH (Menu no. 27). I also have and have used the Baofeng UV-9G programming software. Anyways, when I returned to Channel mode the parameters I just set for channel 31 were there but the radio would not key up (it would tx before on the frequency it was set to from the factory). This seems like a quirky/unclear thing with this radio, the manual is not very clear about the intention of channels 31-116, are they intended to be somewhat customizable repeater channels or are they intended to be "scanner channels" where tx is not allowed. Or both?
