Transmitting Group Calls
Group calls let you call several individual stations in your net (at least 2) at once. Thus, you can use a
group call to communicate with a few select stations, while other stations can still communicate at
will, using other channels available to your net.
You can call up to 5 stations in a group call. The only restriction is that the total length of all the
addresses cannot exceed 12 ALE words (36 characters). If the maximum allowed length is exceeded,
you get a
BUFF FULL error.
Notes
•
If you need to check beforehand the length, remember that as explained on page
37, each ALE word must include 3 characters. Therefore, when an address is not
an exact multiple of 3, stuffing symbols are automatically added in the last
positions.
•
ALE addresses are categorized in accordance with their leading ALE word (that is,
their first three characters: if the address is short and has only one or two
characters, stuffing symbols @ are added). When assembling a group you must
also take into consideration that the maximum number of different address
categories (as identified by their leading word) in one group is 5. If more are
included, then when you try to send the call you will see
UFA WRONG . In this
case, remove addresses to make the group more homogenous.
To make a group call, first you must specify the stations to be included in the group. The addresses of
the stations you include in the group can be saved as a
group ; the radio can store up to 4 different
groups. If a group including the desired stations is already programmed, you can directly initiate the
call to the desired group.
Note Before starting, you may want to select a different net to use: see instructions on
page 53.
When MultiNet is enabled, you will be prompted for a net number as soon as you
press
CALL (F1) to start a call.
