Make sure that you have connected the PK-900 to your transmitter for
direct CW keying as discussed in Section 3.3.6 of this manual.
Although the PK-900 is capable of Morse transmission using Audio
Keying in the SSB mode of a transmitter, direct CW keying is
preferred. Most modern transmitters and transceivers are designed for
direct CW keying and often allow additional filtering to be switched
in for improved Morse reception when operating in this mode.
Adjust your transmitter for Morse operation as described in your
transmitter's manual. Make sure your antenna is tuned and adjusted
for the band and operating frequency you are using.
If you are using a terminal or terminal program, the following will
place your PK-900 and transceiver into the transmit mode.
o Make sure that you have selected your transmitted text to go to
Port 1 by pressing the CHSWITCH character defined in Chapter 4
followed by a number from 0 through 9.
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 your transmitter PTT will be
activated. At this point you are also in the CONVERSE mode and
anything you type will be sent in Morse by your transmitter.
