use encryption.
Four and six digit GPS and Status data calls use the OEM privacy key to encrypt
the data. If this eight digit key has not been programmed by the Barrett 4050
HF SDR Programming Software (P/N BCA40001), a default privacy key of
99999999 is automatically used for transmission.
Six digit Page calls also use the privacy key but unlike the other calls, the user
has the option to manually enable or disable the privacy key. When disabled,
the data is sent as plain text.
Emergency GPS calls are automatically sent as plain text (four and six digit).
Station ID Ranges
The standard Selcall system accommodates four and six digit networks.
Station IDs range from 000000 to 999999 inclusive (the destination ID must be
either four or six digits long).
