COMMAND DESCRIPTION PARAMETERS RANGE
FEC,{HISTORY,n} The FEC,HISTORY,n command defined the
number of transmissions that will be used by the
algorithm to compute the number of errors
correction parity bytes for each subsequent
transmission. “n” can be set from 1-19. The size
of the history queue determines how many
points are averaged, and can effect the
responsiveness to changes in the RF
environment much like a low-pass filter. The
longer the queue, the slower the response, and
the shorter the queue, the quicker the response.
The default value is 5.
FREQUENCIES Shows the Active Transmitter and Receiver
frequency and the frequency table where up to
10 frequency channels can be defined.
To change/set the frequency of the radio is a
two step process:
Select the TX and RX Frequency, along with the
channel number to be assigned to that
frequency in the frequency table.
Assign that channel to the frequency synthesizer
from the frequency table.
