CW MODE
A key, keyer, or other keying device must be connected to the KEY
input on the rear panel. To set up keying via a computer,
see USB and RS-232.
A paddle directly connected to the PADDLE input takes advantage of
the K4's built-in keyer function, eliminating the need for an external
keyer. This also allows your own CW to be displayed in the text-
decode window. You can use the paddle to transmit in FSK and PSK
modes, as well, by sending CW characters.
CW can be sent while in SSB modes. This feature must be enabled
using the CW TX in SSB Mode menu entry.
CW Mode Basics
• Keyer speed is set using {XMTR} <WPM>.
• To set the desired sidetone pitch, use {XMTR} <PTCH>. Note:
Sidetone pitch is adjustable in 10 Hz steps. However, selecting a pitch
that's a multiple of 50 Hz will provide better passband alignment when
IIR filters are enabled. See MENU: RX CW IIR Filters (50-200 Hz).
• Sidetone volume is adjusted by holding the {XMTR} knob to select its
[MON] function (monitor). To set the LINE OUT sidetone level, use
MENU:TX Monitor Level, Line Out.
• To practice sending CW without putting out any power, hold [TEST]
to enter TX test mode. The TX icon will change to TX Test.
• To use hit-the-key transmit, [VOX] must be turned on. If VOX is off,
you'll need to tap XMIT to enter transmit mode, or use a foot switch or
other device connected to the PTT IN jack.
• For fastest break-in, turn on [QSK]. For more casual QSOs, you may
wish to leave QSK off, resulting in slightly slower receive recovery
between elements, thus a less "busy" sound during keying. When QSK
is off, {XMTR} <DLY> sets the receive recovery delay in .01-second
steps. (Also see MENU:TX QSK Method, which provides two choices
for optimizing QSK mode.)
