Rev. 1.3
EDIT RX FREQUENCY:
72.2345 MHz (PRESS ENT)
Edit the receive frequency. This is accomplished by selecting the digit to be
edited, using the LEFT/RIGHT arrow keys. The value of the digit is then

The range of frequencies is from 52 - 88 MHz (70 MHz factory option) or 104 -
176 MHz (140 MHz factory option).
EDIT RX DATA RATE:
64.000 kbps (PRESS ENT)

using the LEFT/RIGHT arrow keys. The value of the digit is then changed using
the UP/DOWN arrow keys. The user should then press ENTER. The overall
range of data rates is from 2.4 to 2048 kbps.
NOTE: The minimum and maximum data rates are dependent on modulation
type and FEC decoder rate. If the user changes the modulation or FEC, and the
currently selected data rate is then invalid, it will be adjusted automatically.
If either the Reed-Solomon Codec option or the Turbo Codec option are not
installed, the following menu will be displayed:
SELECT FEC TYPE: VITERBI
