7.7.2 Displaying Received Data
The Radio command may be used to disable port 2. This may be
desirable when operating RTTY and you do not want to be disturbed with
any packet signals that may be received on radio port 2. To disable
port 2, enter:
RADIO ON/OFF <Enter> or RADIO 1/0 <Enter>
For dual port operation, type
RADIO ON/ON <Enter> or RADIO 1/2 <Enter>
The PK-900 sorts and displays received data from each Radio Port
using the same technique as multi-connect packet operation described
in Chapter 4. That is, when operating on one port and the other
port becomes active, the displayed data from the inactive port is
shown prefaced by the "channel designator" followed by a colon (:).
Recall that Radio Port 1 is designated by "logical" channels from 0-9
and that Port 2 is designated by "logical" channels A-Z.
7.7.3 Switching Between Ports
If you are using an AEA PAKRATT program, switching between Radio Ports
is described in the program manual. If you are using a terminal
program, this section describes how to direct your transmitted text.
Switching between AMTOR on Port 1 and Packet on Port 2 is similar to
switching between Packet and Packet. If you have not yet read through
the Switching Between Radio Ports section of Chapter 4, please do so
now and define a CHSWITCH character before reading the example below.
Recall from chapter 4 that the channels on Port 1 are labeled 0-9 and
the channels on Port 2 are labeled A-Z. To select Radio Port 1
(AMTOR) press the CHSWITCH character you defined, followed by the
number 0. To select Radio Port 2 (Packet), press the CHSWITCH
character, followed by a letter from A-Z.
For example, you are conversing with an AMTOR station and are in the
middle of a QSO when a station on VHF connects to you. The following
shows how your screen would look and suggests how you might handle
such an occurrence. The underlined text is the text that you type.
Hello Jim, you are printing solid { You send the AMTOR station
here and have an S7 signal.+? a signal report }
THANKS BOB, YOUR ALSO A SOLID S7 { The other station responds
HERE AS WELL.+? with a signal report }
A:*** CONNECTED to WX7EEE { WX7EEE connects to you on
VHF (Radio Port 2) }
Thanks for the signal report Jim { You make another transmission
only running 100 watts here.+? to Jim on HF AMTOR }
