Extra channels are added to the radio via an additional PC Board using two additional crystals to support 40 channels above and 40 channels below the standard 40. This board provides a total of 120 channels.

    This is a complicated modification and should not be done by an amateur. You should probably leave the installation and alignment to a proven technician.   

Transmitting using this radio requires an Amateur Radio License. Licensing information can be obtained by visiting www.fcc.gov or http://arrl.org. In Canada, visit http://strategis.ic.gc.ca or http://www.rac.ca
