Because the same call sign sequences are assigned in ten districts, it is possible that your
SELCALL could be used by another station. If you think a station in another call district is
also active on AMTOR and is using the same SELCALL, see the MYSELCAL command for
information on how to change your Selcall.
7.2.3 Entering Your SELective CALling Code (MYIDENT)
At the present time, most of the AMTOR activity on the amateur bands is using the four-
character SELCALL defined in CCIR 476 and described above. The seven-character SEL-
CALL (MYIDENT) defined in CCIR 625 solves the problem of non-unique SELCALLs by pro-
viding many more possible SELCALLs than CCIR 476 does with four-character SELCALLs.
To enter your seven-character SELCALL all you must do is enter your amateur callsign.
The PK-232 will do the translation for you.
If you are using an AEA PAKRATT program, follow the instructions in the program manual
for entering the command MYIDENT.
If you are using a terminal, then enter the following:
cmd:
MYIDENT N7ML
The PK-232 will tell you, MYIdent now VTMFFFF
See the MYIDENT command in the Command Summary if you are interested in more in-
formation on the translation process.
7.2.4 Enter the AMTOR Mode
Now that you have entered your personal MYSELCAL and MYIDENT Selective Calling co-
des, you are ready to enter the AMTOR mode.
If you are using an AEA PAKRATT program, follow the instructions in the program manual
to enter the AMTOR mode.
If you are using a terminal, simply type AMTOR or AM from the Command Mode followed
by the <Enter> key to enter the AMTOR mode. The PK-232 responds by displaying the
previous mode:
Opmode was PAcket
Opmode now AMtor
Your PK-232's front panel will show the two STBY LEDs lit.
7.2.5 HF Receiver Settings
Set your HF receiver (or transceiver) to Lower Sideband (LSB) unless you connected your
PK-232 through the direct FSK keying lines. In this case, you should select the FSK operat-
ing mode. Adjust the volume to a comfortable listening level.
