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 RTTY station you are communicating with.
Notice that you must type an "x" followed by the Enter key on the
keyboard to place Radio Port 1 of the PK-900 into RTTY Transmit mode.
When you are through sending your signal report to Jim on HF RTTY, you
tell the PK-900 to return to receive by sending a <CTRL-D>. The
PK-900 then responds with the Command Prompt "cmd:".
The next text you see is your signal report received from Jim on RTTY.
You are in the middle of a QSO with Jim on HF RTTY 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
HF RTTY telling him how much power your transmitter is running. In
order to do this however you must first enter the command mode of the
PK-900 by typing a <CTRL-C> and then giving the RTTY Transmit
command "x" followed by the <Enter> key. When you are finished with
your text, you command the PK-900 back to receive with a <CTRL-D>.
After making this transmission on HF RTTY, 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.
