the modem number set in the QRTTY command. You may wish to change the
number in QRTTY to the modem number you prefer to use in Baudot RTTY.
6.7.2 Displaying Received Data
The Radio command may be used to disable port 2. This may be de-
sirable 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
To enable both radio ports, type:
RADIO ON/ON <Enter> or RADIO 1/2
When a Dual Port operation is selected, 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 DX
spotting nets.
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. This is
true whether single port or dual port operation is selected.
6.7.3 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 RTTY 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 (RTTY)
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 HF RTTY station and are in the
middle of a QSO when a station on VHF connects to you. The follow
ing shows how your screen would look and suggests how you might
handle such an occurrence. The underlined text is the text that you
type.
