Band Edges
The frequency range of the transceiver is 118 to 136.975 MHz for the B6550/NB version, or 112 to
155.975 MHz for the B6550/WB version.
If required, reception can be limited to either one or two smaller parts of the frequency band by setting
the band edges BE1 to BE4. Reception is possible between BE1 and BE2 frequencies, and frequencies
between BE3 and BE4.

The Band Edge screen is accessed from the
Control screen.
Band edge frequencies can be set only in
increments of 25 kHz.
If the transceiver is required to operate over the
full range, the band edge parameters must be set
to the lowest and highest values in the range (see
Table 10 ).
