Has anyone figured out a way to hack one for extra channels yet? My 257hp died and I'm thinking this to get me by but keep looking back at a 959b also. I like my 257 but found myself never going outside of 27.185 - 27.555. Before anyone says it, no I'm not buying another 10 meter radio and no the 257 isn't for sale....I own 2 of them but since 1 is out I need a new mobile unit.
