Individual Station Address
The individual station address may contain 1, 2, 3, 4, or 5 words. To enable using addresses that are
not an integer multiple of 3 characters (for example, an address consisting of 1, 2, 7, 8, 10, …, etc.
characters), stuffing can be used: with stuffing, the last address word includes one or two stuffing
symbols in the last position(s) (see the “stuff-1” and “stuff-2” patterns in Table 1).
The wildcard symbol cannot be included in an individual station address, nor in a call request to an
individual station.
Table 1. Use of “@” Stuffing Symbol
Pattern Interpretation
A B C
“Standard” 3-character address word, shown here for reference. Only the
station with this address stops scanning and responds
A B @
“Stuff-1” reduced address field, used to add characters “A, B” at the end of the
address
A @ @
“Stuff-2” reduced address field, used to add character “A” at the end of the
address
@ ? @
“AllCall” global address (see also Table 2): all the stations stop and listen (unless
this function is inhibited)
@ A @
“Selective AllCall” global address: each station with the same last character “A”
stop scanning and listen (unless this function is inhibited
@ @ ?
“AnyCall” global address (see also Table 2): all the stations stop scanning and
respond in randomly selected timeslots (unless this function is inhibited)
@ @ A
@ B@
(option)
“Selective AnyCall” address: each station with same last character(s) “A” (or
“B”) stops scanning and responds in a randomly selected timeslot (unless this
function is inhibited), using its own address
@ A B
@ C D
(option)
“Double selective AnyCall” address: each station with same last characters “AB”
(or “CD”) stops scanning and responds in a randomly selected timeslot (unless
this function is inhibited), using its own address
@ @ @
“Null” address; all the stations ignore this address. The null address intended
for use in test and maintenance, or to create an extra “buffer” timeslot
Net Addresses
The purpose of a net call is to rapidly and efficiently establish contact with multiple prearranged (net)
stations. This is achieved by the use of a single net address.
The net address is actually an additional address assigned in common to all the stations that are
members of a specific net. Its address structure is identical to that used for individual station addresses
(basic or extended, with or without stuffing, as necessary).
When defining a net, each member station is automatically assigned a timeslot: by having each
station answer a call request in a different timeslot, collisions are avoided.
