A fellow ham gave me 5 Icom U12 commercial radios, which I'd like to put
on the 440 MHz ham band. Upon inspection, they are dead ringers for the
old IC-4AT series of transceivers (even have silk-screened outlines for
the three mini switches on the back). I need a schematic and PCB layout
so I can move them down about 10 MHz.

Thanks,
