On the top line, use the   arrow keys to select a parameter. Press ENTER. The read-only
bottom line shows the operating data rate (in kbps) and symbol rate (in ksps).

6.2.2.2.1 (CONFIG: Tx) Mod

ModCod=8PSK
Pilots:On
Use the   arrow keys to select a parameter. Press ENTER.
(CONFIG: Tx) Mod  ModCod, 0/0 (FEC)
Use the   arrow keys to toggle between selecting the ModCod or FEC.
For ModCod – Use the arrow keys to make your selection. Valid settings are QPSK, 8PSK,
16APSK, 32APSK, or ACM.
The 16APSK, 32APSK, and ACM (Adaptive Coding and Modulation) settings require that
the unit is already configured to permit these modulation types.
Select ACM for ACM Mode. In this mode, the modulator uses the ACM parameters (selected in the
CONFIG: Tx → ACM menu) and the remote Es/No modem reading to automatically set the
modulation type and FEC.
For FEC – Use the arrow keys to make your selection. Press ENTER. ModCods and coding are
valid for the listed network specifications as follows:
