Note: Digit values in a frequency-programming command string that are not preceded by an alphabetic
character will decrement in position from highest-to-lowest frequency digit position value, based on the
location in the string of the last alphabetic character entered.
Frequency programming examples:
1.
H12345678,
H1G2F3E4D5C678,
or
A8B7C6D5E4F3G2H1
sets frequency = 12,345.678 MHz
2. With frequency = 12,345.678 MHz,
G4C1B2A3
changes frequency to 14,345.123 MHz
3. With frequency = 14,345.123 MHz,
H0F9E87
changes frequency to 4,987.123 MHz
