I got my Noble in a couple weeks ago and just updated the firmware the other day. I only need 4 channels, so I picked the 4 channel firmware. Since the 4 channel firmware is no longer being developed, should I do another update with the 8 channel? When does it give you the option to select 4,6 or 8 channel using the 8 channel firmware? Is it during the install, or is it a menu option on the radio after you install it?
