One volume knob would cause me to tear out my radio completely.
I can set the overall volume via the intercom, Then my music volume can be adjusted via the device, Rarely do I touch this though after all the overall volume has been set. Now the radio that is the only volume I touch during a weekend and that is only because of to many chatty Kathys, Last ride I noticed it was all the way down to 1 it was so bad.
Please before you touch the PTT button ask yourself these questions
Do I need to say this? Does everybody within 100 miles need to hear this?
And If you do need to press that button please say the persons name your trying to get a hold of, You don't know how much fun it is to be hauling the mail thru something when all of a sudden you hear hole or drop or did they say stop ? Only to find out it wasn't your group
And yes we have a non-listed channel but it always seems like there is that one person who doesn't have it programmed yet.
