To allow for multiple stations by the same operator, we borrow the use
|
||||
of the '-' character from AX.25 and the SSID field. A callsign such as
|
||||
"KR6ZY-1" is considered a different station than "KR6ZY-2" or even
|
||||
"KR6ZY", but it is understood that these all belong to the same
|
||||
operator, "KR6ZY"
|
||||
"AB1CD-1" is considered a different station than "AB1CD-2" or even
|
||||
"AB1CD", but it is understood that these all belong to the same

operator, "AB1CD"

Temporary Modifiers
|
||||
~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Similarly, suffixes are often added to callsign to indicate temporary
|
||||
changes of status, such as "KR6ZY/M" for a mobile station, or
|
||||
"KR6ZY/AE" to signify that I have Amateur Extra operating privileges

|
||||
even though the FCC database may not yet be updated. So the '/' is
|
||||
included in the base40 alphabet. The difference between '-' and '/'
|
||||
is that '-' are considered different stations, but '/' are NOT. They
|
||||
are considered to be a temporary modification to the same
|
||||
station.

Interoperability
|
||||
~~~~~~~~~~~~~~~~
|
||||
|
||||
It may be desirable to bridge information between M17 and other
|
||||
networks. The 9 character base40 encoding allows for this:
