Any modem from this list may be selected with the command MODEM. For
example, let's say that you want to operate 300 bps HF packet on radio
port 1 and 1200 bps VHF packet on radio port 2.
This operation is achieved with radio port 1 modem 10 and radio
port 2 modem 4. To load these modems, first enter the Command
Mode of the PK-900 and then type MODEM 10/4 as shown below:
MODEM 10/4 <Enter>
The PK-900 will respond with the following:
MODem was x/x (whatever modems were in use)
MODem now 10/4
cmd:*** HBaud now 300/1200
Either modem may be selected individually. To change only radio
port one's modem, for example, type MODEM 10 <Enter>. To change
only radio port two's modem, you would type MODEM /4 <Enter>.
4.8.2 Displaying Received Data
When radio port 2 is active in the PK-900, received data is displayed
from both Radio Ports at the same time. This allows you to operate
on HF and not miss any local Packet connects or information from VHF
DX spotting nets.
The PK-900 displays monitored packets by prefacing each packet with
a port designator "p1" for radio port 1 and "p2" for radio port 2.
For instance, let's say that modems 10/4 are selected and you
are monitoring HF packet activity on Radio Port 1, and VHF packet
activity on Radio Port 2. You might see something like the following:
p1 WX1AAA*>CQ [UI]: { WX1AAA calling CQ on
Radio Port 1 (HF) }
p1 WX1AAA*>CQ [UI]:
p2 WY7DDD*>WY7EEE [I,P;1,1]: { An Information Frame from
Hello Bob, how are you? WY7DDD to WY7EEE monitored
on Radio Port 2 (VHF) }
p2 WY7EEE*>WY7DDD (RR,F;1) { Acknowledgment of the above
I-Frame on Radio Port 2 }
p1 WX2BBB*>WX1AAA [C,P] { WX2BBB attempting to connect
to WX1AAA on Radio Port 1 }
p1 WX1AAA*>WX2BBB (UA,F) { WX1AAA acknowledging the
connect request }
p1 WX2BBB*>WX1AAA [I,P;0,0]: { An Information Frame from
Hello Bob, how are you? WX2BBB to WX1AAA monitored
on Radio Port 1 (HF) }
The first packet shown above is an Unprotocol "CQ" packet from WX1AAA
that was received on Radio Port 1. We know this was received on Port
1 because of the "p1" shown in front of the packet. (Remember from
