The Operational Screens are similar to the LOS screens.
• Squelch Indicator: Even though SATCOM uses digital squelch, because
Squelch Type is disabled the Indicator displays ---.
• Preset Type: LOS or SAT. (Can be over-ridden).
• Modulation Type: FSK, SBPSK, or CPM. FSK for 25 k wideband VINSON,
SBPSK for 5 k narrowband ANDVT, and CPM for most KG-84 data rates.
• Channel Number: Satcom channel number is now displayed. (Can be over-
ridden).
• Crypto Key: 01 to 25. (Can be over-ridden). CRYPTO TYPE is also changed
when overriding the Crypto Key.
