Background
Operaten above the UHF-AM
aircraft band
at in the 420 to 450 MHz range with a direct sequency spread
spectrum
TDMA signal that's 3 Mhz wide. Note this is not
frequency hopping
like in the SINCGARS radios.
Related systems are the Near Term Digital Radio (aka: Near Term Data Radio, NTDR), Joint Tactical Information Distribution System (JTIDS) uses LINK 16 TDMA, Multifunction Information Distribution System (MIDS) also a LINK 16 system, Joint Tactical Radio System (JTRS) covers 2 to 2,000 MHz.
