BARRETT PRC-4090 TACTICAL HF SDR TRANSCEIVER - SELCALL
Important Selective Calling Information
Selcall
Self IDs
The PRC-4090 transceiver can hold up to 14 different Selcall Self IDs assigned
to it. These Selcall IDs can be any combination of four or six digit OEM or INT
type ID.
Selcall Decode
The transceiver has the ability to decode both OEM and International Selcalls
on any channel programmed as a Selcall channel. However, the call must be
addressed to the relevant ID (OEM or INT).
Calls for each format type will only be decoded if there is at least one Self ID of
that format programmed into the transceiver Self ID group.
Selcall Transmit
Selcall formats in transmit are channel specific. For example, only call types
programmed for the channel are permitted. This means International format
calls can only be sent on channels that are programmed as International Selcall
channels. OEM calls can only be sent on channels that are programmed as OEM
Selcall channels
Special Notes for the
OEM Selective Call Protocol
•
Six digit
OEM calls will only be decoded by other Barrett transceivers fitted
with the OEM Selcall protocol or other manufacturer’s transceivers that
use DES56 encryption. This does not require an export permit.
•
Four digit OEM calls will be decoded by Barrett 950 and 2050 transceivers
using the International Selcall (four and six digit) and other manufactur-
er’s transceivers with similar CCIR-493 based Selective Call systems.
•
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
programming software, a default privacy key of 99999999 is automati-
cally used for transmission.
•
Four and 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).
