As you may have noticed, communicating with different modes on the two
Radio Ports at the same time is almost identical to the method used in
chapter 4 for Packet and Packet operation. Let's discuss the sample
QSOs above to see how the Port switching occurs.
The first text we see in the sample above is the signal report you are
sending to Jim, the HF AMTOR station you are communicating with. This
example assumes you have already set up the ARQ AMTOR contact with the
ARQ command discussed earlier in the chapter. When you are through
sending your signal report to Jim on AMTOR, you turn the link over to
become the IRS by sending the "+?". The PK-900 then responds by
sending a blank line to the display to break up the received text.
The next text you see is your signal report received from Jim on
AMTOR.
You are in the middle of a QSO with Jim on AMTOR and all of a sudden
your friend WX7EEE connects to you. WX7EEE has connected on Radio
Port 2 (VHF) which is shown by the "A:" before the connect message.
Remember that the 26 channel designators for Radio Port 2 are A-Z.
Before you respond to WX7EEE on VHF, you send a transmission to Jim on
AMTOR telling him how much power your transmitter is running. When
you are finished with your text, you again command the PK-900 to be
the IRS by sending a "+?".
After making this transmission on AMTOR, you see WX7EEE on VHF has
offered you a ride to the hamfest. We know this text is from Radio
Port 2 since the previous packet displayed by the PK-900 was the
"A:*** CONNECTED" message from Port 2.
Now you want to let WX7EEE on VHF know that you are there, but that
you are involved in another QSO on HF. This way he will understand
that it may take you a little longer to respond to his packets.
Before you can send data to Radio Port 2, you must switch to this Port
with "|A" or the text you type will be sent to Radio Port 1 on AMTOR
when Jim turns the link over to you again.
You receive a transmission from Jim on AMTOR telling you he needs to
sign off to go to bed. The "0:" in front of the text shows this was
received on Radio Port 1.
Now you want to sign off with Jim on HF. Again, first you must switch
to Radio Port 1 with the "|0" since your last transmission was
directed to Port 2. Now you can make your final transmission to Jim
