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. Designed for use with the NB/ANL switch as a frequency band selector but can use any switch you like.  I have not been able to get good Clarifier control of these boards and frequency alignment is difficult sometimes.  I recommend the Lescomm boards for the Galaxy 959 and 2547 type radios. I recommend this board for AM only radios.

26.515 - 27.855

    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
