PK-88 OPERATING MANUAL
4.1.2
Station Identification
Use the MYCALL command to install your call sign in the PK-88's memory (see
next section). The PK-88 will not key your transmitter until you've changed
the MYCALL default "PK88" to a valid call sign.
4.1.2.1 MYCALL Required at System Start-Up
When you start the PK-88 for the first time, the system parameters are loaded
from EPROM. MYCALL is initialized using "PK88" as its default. You must use
the MYCALL command to install your call sign in the 88. You cannot operate
until you have done this. If you try to connect to a station without
installing your call sign, the PK-88 will not transmit, but instead sends you
this error message:
?need MYCALL
4.1.2.2 Substation Identifiers (SSIDs)
You can identify additional stations with the Secondary Station ID, or SSID -
a number from 0 to 15, appended to the call sign by a dash:
cmd:MYCALL WX1XXX
If you do not specify the SSID extension, the PK-88 retains its default value
of zero (0) and the SSID is not displayed. You must specify the SSID to
connect to a station with a SSID other than 0 or use such a station as a
digipeater:
cmd:CONNECT WX1XXX-2 (or)
cmd:CONNECT WXlAAA VIA WX2BBB-2
4.1.2.3 Automatic Identification
The PK-88 can send an automatic identification (ID) packet every 9.5 minutes
when your station is a digipeating. You can turn this feature on with the
command HID ON. ID packets are displayed like this:
WXlXXX>ID:WXlXXX digipeater (or)
WX1XXX>ID:(MYALIAS), WX1XXX digipeater
When you shut down, you can command a final ID with the ID command.

Set Up Loopback Test Circuit
Do these steps in the exact order shown:
1.
Get the shielded radio cable you set aside in Chapter 2.
2.
Strip and tin the wires at the radio end of the cable.
3.
Join the wires coming from pins 2 and 8.
4.
Insert the eight-pin plug end of the cable into the J2 connector
on the PK-88's rear panel.
You have connected the PK-88's transmit audio output to its receive audio
input. The PK-88 can now 'talk to itself' in 'loopback.'
