Ham Callsign to ALE Address Standard Protocol

==STANDARD HAM CALLSIGN CONVERSION TO ALE ADDRESS==
This document discusses the standard conversion protocol for amateur radio 'operator callsign' or 'station callsign' to ALE self-address. A unique ALE self-address is required for proper operation on the air using ALE.

==AMATEUR RADIO CALLSIGN AS ALE ADDRESS==
Since 2001, amateur radio operators have been operating in organized nets using ALE. Universal use of operator callsign or station callsign was adopted, and this simple callsign forms the basis of the present global standard of ALE self-address.
ITU international allocation agreements require that amateur callsigns normally are CAPITAL ALPHABET characters and NUMERIC DIGITS. This is compatible with ALE self-address requirements. The basic original callsign is always preferred as ALE self-address whenever possible.
Example:
Callsign = ALE Address
KQ6XA = = KQ6XA
 
==ALE STANDARD ADDRESS PROTOCOL==
The world standard ALE system is known as 2G ALE. The 2G ALE system can ONLY use an ALE address containing the basic 36 ALPHA-Numeric characters:
26 Characters of ALPHABET (A-Z) ALL CAPS
10 DIGITS (0-9)

Valid ALE Self-Address characters:
ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789

No other characters can be in the ALE Self Address. The ALE address must be less than 15 characters long.

==PORTABLE-MOBILE-MULTIPLE-RECIPROCOL-CALLSIGNS==
Operators may desire (or require) the use of additional indicators to expand their callsign with more characters when operating portable, mobile or in a different location or country from the operator's original callsign. But, careful conversion using this standard avoids confusion,
duplication, or invalid ALE address. Also, it enables the protocol to be used for consistent station identification.

An operator may have multiple different stations or ALE radios, and may want to differentiate the ALE self-addresses for identification, EmComm incident situations, or messaging/inbox data traffic purposes.

Traditionally, on voice or CW, these additional callsign indicators have used the /slash (slant-bar) for /M (mobile) or /P (portable). However, the /slash is not a valid ALE address character,
so it CAN NOT be used for ALE self address!

==CONVERSION OF /SLASH==
The standard conversion method of /slash indicator to ALE self-address depends on whether the indicator is before or after the original callsign.

=PREFIX /SLASH=
If the expanded character callsign indicator precedes the main callsign (such as operation in another country) then DELETE the slash to form the ALE self-address.
Example:
CALLSIGN = ALE ADDRESS
VR2/KQ6XA = VR2KQ6XA

=SUFFIX /SLASH FOR MOBILE OR PORTABLE=
If the expanded character callsign indicator comes after the main callsign (portable or mobile) then ADD a SINGLE DIGIT.
Examples:
CALLSIGN = ALE ADDRESS
KQ6XA/M = KQ6XA1
KQ6XA/P = KQ6XA2
KQ6XA/4 = KQ6XA4

=ALTERNATIVE SUFFIX /SLASH=
If the operator requires more alphabet characters after the main callsign, then REPLACE /slash with DIGIT "1" and add ALPHABET CHARACTERS
Examples:
CALLSIGN = ALE ADDRESS
KQ6XA/P = KQ6XA1P
KQ6XA/MM = KQ6XA1MM
KQ6XA/VE9 = KQ6XA1VE9

==INVALID ALE ADDRESS CHARACTERS==
Here is a list of common mistakes.

lower case letters are not valid for ALE self-address...
/ is not valid for ALE self-address...
* is not valid for ALE self-address...
- is not valid for ALE self-address...
? is not valid for ALE self-address...
_underbar is not valid for ALE self-address...
other ascii characters are not valid for ALE self address...

...and all these invalid characters will cause bad problems for ALE use.

==SIMPLE IS BETTER==
Keep in mind, when converting callsign to ALE self-address:
Minimum characters in the ALE address improves linking reliability. It is alays wise to use the basic simple callsign as the self-address if possible.
