o Adjust the PK-232's THRESHOLD control so that the DCD LED lights
when a properly tuned RTTY station is being received.
HINT: If you adjust the THRESHOLD control so the DCD LED goes out
when no station is being received, you will prevent garbage
characters generated by noise from printing on your screen.
After you have an ASCII or RTTY station tuned in, you should start
seeing the copy printing on your screen.
If the text you are receiving is garbled, you may be tuned to a
transmission at a different baud rate. Either try tuning in a
different station, or see Chapter 10 on SIGNAL IDENTIFICATION to let
the PK-232 determine the kind of station you are listening to.
6.3 Transmitter Adjustments
Make sure your PK-232 is adjusted for your SSB transmitter as
described in section 3.5 and 3.5.2 of this manual before transmitting.
These are very critical adjustments. If your PK-232's AFSK level and
transmitter microphone gain are not adjusted properly, other stations
will not be able to copy your signals. Check your plate or collector
current or the power output of your rig before going on the air.
6.3.1 Going On The Air
Make sure your transmitter and antenna are tuned and adjusted for the
band and operating frequency you are using. If you are using an AEA
PAKRATT program, see the program manual for the proper way to place
the PK-232 into RTTY transmit mode.
If you are using a terminal or terminal program, the following will
place your PK-232 and transceiver into the transmit mode.
o Type "X" for XMIT and then press the <Enter> key to key your
transmitter and automatically enter the Converse mode.
As soon as you type the <Enter> key you will be transmitting. At this
point you are also in the CONVERSE mode and anything you type will be
sent in Baudot by your transmitter.
When you are finished transmitting, use one of the following methods
to return to receive.
o Type <CTRL-D> to shut off your transmitter and return to the
Command Mode.
o Type <CTRL-F> to send a Morse ID and shut off your transmitter
and return to Command Mode.
o Type <CTRL-C> to return to the Command Mode and then type "R" to
shut down your transmitter and end the contact.
See the following sections for a sample QSO as well as some Baudot
operating hints.
