Timewave PK-900, Operating Manual, Page: 44 / 392

4.2 Packet Introduction
You've now connected your PK-900's transmit audio output to its
receive audio input. Your PK-900 can now "talk to itself" in
packet.
1. Set the rear-panel AFSK level control for RADIO-1 at 50%
(straight up and down) for the following Packet introduction.
NOTE: If you have adjusted the RADIO-1 rear-panel AFSK level
control for a particular transceiver in chapter 3, then mark
this setting with a pencil so it can be reset when finished.
2. Turn on your computer. Load and run your communications program.
If you are using an AEA PAKRATT Program, follow the program
manual's instructions to enter the Packet mode on Radio Port 1,
and then skip to step 4.
If you are using another Computer program or a Terminal, set the
communication parameters as done in Chapters 2 and 3.
3. Press the PK-900's front panel power switch to the ON position
if you have not already done so.
You should notice the sign-on message seen in chapter 2. The LCD
Status display should indicate you are in the Packet mode.
4. After you have seen the sign-on message and/or entered the Packet
mode, you must enter your own callsign (with the MYCALL Command)
if you are to converse with any other Packet stations. If you
try to connect to a station without entering your call sign, your
PK-900 will send you the following message:
?need MYcall
If you are an SWL and do not intend to transmit, you should enter
"AAA" as a Callsign (MYCALL).
If you are using an AEA PAKRATT program, follow the instructions
in the Program Manual to enter your callsign. If you are using a
terminal or terminal emulating program on your computer, you must
use the MYCALL command to install your call sign.
Note that since the PK-900 has two radio ports, you must enter
a callsign for each port. The callsigns may be the same, or can
be different to make life a little easier in the "two Ham"
family. You must change the callsign from the default "PK900"
on each radio port, or that port will not transmit packets. For
example, if your Callsign is WX2BBB, enter the following:
cmd:MYCALL WX2BBB/WX2BBB <Enter>
The PK-900 will respond with:
MYcall was PK900/PK900
MYcall now WX2BBB/WX2BBB
