lows you full access to all commands. To enter TERMINAL mode, at the cmd:
prompt type
INT TERMINAL <return>.
Then turn the KAM’98 off and back on, or at the cmd: prompt type RESET. You
are now in general TERMINAL mode. In fact, it may be that you’ll never change
this setting from now on. If you wish to go back to NEWUSER mode, just issue a
reset after entering the command INT NEWUSER. See INTface in the command
reference for more detail and additional choices.
Monitoring some HF Modes
Perhaps the quickest way to gain familiarity with using the KAM’98 to work the
HF digital modes is to monitor a few of these modes. Radio teletype (RTTY) and
Pactor are very popular on the 40 and 20 meter bands (7.0 and 14.0 Mhz), so try
using your HF Single Sideband transceiver (SSB radio), set in lower sideband
(LSB) mode, to copy these signal modes with the KAM’98.
+ RTTY transmissions are a steady sequence of 2125 and 2295 Hertz tones.
Pactor signals sound similar but pulsate at roughly a one second rate.
If you haven’t wired the output of your SSB radio speaker to the KAM’98 yet, do
so now. With it wired, turn it on and tune it to 14080 kilohertz, a portion of 20
meter digital band. Tune up and down the band a bit and you should readily find
both RTTY and Pactor signals.
Radio Teletype
To copy RTTY, i.e., display it on your computer screen, enter the following com
-
mand at the “cmd:” prompt
cmd: RTTY <return>
The KAM’98 will respond with the message:
RTTY 45
You are ready to copy RTTY at 45 baud. Tune your dial up and then down until
you hear a RTTY signal. Once you’ve located one, adjust your dial until the left
