PK-232 – MBX OPERATING MANUAL COMMAND SUMMARY
4/91 A-58 183
Use the MYALTCAL command to specify an your alternate SELCALL which, under certain condi-
tions, may be convenient or necessary. You can enter an additional SELCALL code not related to
your call sign. The alternate SELCALL can be any four alphabetical characters, or can be numeric
strings of either four or five numbers. MYALTCAL is generally used for special applications such as
receiving network or group broadcasts in AMTOR Mode B Selective (Bs or SELFEC).
MYcall call [-"n"] Default: PK232
Mode: Packet Host: ML
Parameters: call - Your call sign
"n" - 0 - 15, indicating an optional substation ID, (SSID)
Use the MYCALL command to load your call sign into your PK-232.
The "PK232" default call sign is present in your PK-232's ROM when the system is manufactured.
This "artificial call" must be changed for packet operation.
Two or more stations cannot use the same call and SSID on the air at the same time. Use a differ-
ent SSID if you have more than one packet station on the air.
MYIdent aaaaaaa[aa] Default: none
Mode: AMTOR Host: Mg
Parameters: aaaaaaa[aa] - Specifies the 7-character SELCALL as described in CCIR Rec. 625. The
MYIDENT command holds the CCIR Rec. 625 seven-character AMTOR SELCALL.
Amateurs may simply enter their callsign and the PK-232 will automatically translate it to a 7-char-
acter SELCALL as shown below:
MYIDENT KA1XYZ becomes MYIDENT KAIXYZZ
If aaaaaaa[aa] is nine numerals, the unit translates the numerals to seven letters according to Rec-
ommendation 491. If aaaaaaa consists of seven legal characters, the PK-232 accepts the charac-
ters without modifying them. Legal SELCALL characters for Rec. 625 are the letters A-Z except G,
H, J, L, N and W.
If aaaaaaa is a string of characters of any length that includes illegal characters, the PK-232 will do
the following translation on the characters:
0: O 4: Y 8: B J: U
1: I 5: S 9: P L: F
2: Z 6: D G: C N: V
3: E 7: T H: K W: M
All other letters are unchanged.
If MYSELCAL and MYIDENT are both none (defaults), no incoming ARQ or SELFEC call can estab-
lish communications with the unit.
