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