8. You have just done the three things necessary in any Packet QSO.
o You started the QSO (with yourself) by CONNECTing. (Step 5)
o You sent some information (to yourself) and then received
the information that you sent. (Step 6)
o You then ended the QSO by DISCONNEcting. (Step 7)
Repeat steps 5, 6 and 7 above until you feel comfortable with
Connecting, exchanging information and Disconnecting. These
operations will be performed each time you use Packet so they
should be second nature to you before going on the air.
When you feel comfortable Connecting, sending information and
Disconnecting, you are ready to start listening to VHF packet.
9. Turn OFF and remove power from the PK-900.
o Return the Port 1 rear-panel AFSK level potentiometer to
the setting you marked in Step 1, if any.
o Remove the "Loop-back" jumper from the RADIO-1 port and
reconnect your transceiver or receiver set-up in Chapter 3.
4.3 VHF/UHF Packet Operation
We will first listen to (and watch) some of the VHF or UHF Packet
activity in your Local Area. This will allow you to become a little
better acquainted with packet in your area before going "On The Air".
1. Construct a Radio Cable for the VHF/UHF transceiver you intend to
use for Packet as described in Chapter 3 and connect your
transceiver to the RADIO-1 connector on the PK-900 rear panel.
2. Load and run your communications program and enter the Packet
Mode as done in the Packet Introduction section above.
3. Set Radio Port 1 for VHF Packet operation (default) as follows.
If you are using an AEA program, follow the instructions to
select the VHF modem on Port 1 by turning the VHF Parameter ON,
this will automatically set the radio baud rate HBAUD to 1200.
If you are using a Computer Terminal or a non-AEA terminal
program, the following sets the VHF mode of the PK-900:
Type <CONTROL-C>. (Type C while pressing the <Ctrl> key down.)
Your monitor should respond with the command prompt:
cmd:
Then enter VHF ON <Enter>
Your monitor should respond with:
