Using 'g' means that channels will be used starting with the lowest available 
number and then counting up. Starting with 'G' means to start at the highest 
channel number and count down. I believe that incoming calls will use the lowest 
numbered channels first, so if your outgoing calls start with the higher numbers 
it decreases the chance for "glare" on calls.
