BARRETT PRC-4090 TACTICAL HF SDR TRANSCEIVER - ADVANCED OPERATION
Collective Call
Collective calls comprise of all-calls, group calls and sub-group calls which
involve calling a number of Selcall IDs simultaneously. This is not an individual
button in the Selcall menu as a transceiver can group call as a number of call
types. For information on other call types please refer to Chapter 3 - Selcall,
All call, Group call and Sub-group call must be enabled in the Barrett PRC-4090 HF
SDR
Programming Software (P/N BCA40001).
Sending a Group Call
It is recommended that transceivers should be programmed with a selcall ID
ending in “0” as this is used for making group calls. When prompted to enter a
Selcall ID for a chosen call type, the first digits represent the groups of IDs you
wish to contact.
Four Digit format
All call
eg. Entering 2000 will contact every transceiver on the channel with an ID that
begins with “2”
Group call
eg. Entering 2300 will contact every ID on the channel that begins with “23”.
Sub-group Call
eg. Entering in 2310 will contact every ID that begins with “231”
Six Digit format
Same as above. No more than the last 3 digits can hold the 0 value.
eg. Entering 123000 will contact every transceiver beginning with “123”
