Using Markers
Tap
M K R A
to turn on marker A and allow you to
change the marker frequency by rotating the
SELECT
knob. To determine the frequency of a
signal, move the marker so that it overlays the
carrier and read the frequency from the display. For
single sideband signals, place the marker where the
carrier would be if it were transmitted, i.e. on the
lower (left) edge of an upper sideband signal and on
the upper (right) edge of a lower sideband signal.
If a K3 is connected, you can QSY (change the
frequency of) the K3's VFO A to the marker A
frequency by tapping the
SELECT
knob. To
return to the previous frequency, hold the knob. To
turn off marker A, tap
M K R A
again.
Hold
M K R B
to turn on marker B and allow you to
change the marker frequency by rotating the
SELECT
knob. If a K3 is connected, you can
QSY the K3's VFO B to the marker B frequency by
tapping the
SELECT
knob. To return to the
previous frequency, hold the knob. To turn off
marker B, hold
M K R B
again.
To turn off a marker you must first make it active, if
necessary, by tapping
M K R A
or holding
M K R B
.
Then tap or hold the key a second time to hide the
marker.
If some other function that uses the
SELECT
knob is activated, the marker stays on and
automatically becomes active again (you can adjust
it with the knob) when the other function is
terminated. The tap-to-QSY function affects VFO
A if marker A is active and VFO B if marker B is
active.
When a marker is turned on, it will be at the same
frequency as the last time it was on unless that
frequency is off-screen. In that case the marker is
automatically reset to the display center frequency.
(If you lose a marker off-screen, just turn it off and
on again to return it to the center frequency.)
When you change bands on the K3, the markers are
automatically set at the new center frequency.
For best frequency accuracy, especially when using
narrow spans, perform the frequency calibration
procedure on page 31.
Waterfall Markers
Select
MENU:WfallMkrs
. Tapping the
SELECT knob will turn the waterfall markers
on, causing the marker line(s) to travel down into
the waterfall display, or turn the markers off.
Marker A Enabled at 3563 KHz for Both Spectrum
and Waterfall.
Using Cursors
When used with a K3 transceiver, cursors show the
position of the A and B VFOs, The position and
width of each cursor shows the passband being
received. Two cursor shapes may be selected using
MENU:CURSOR
, a translucent bar cursor or a “U”
shaped cursor at the bottom of the spectrum display.
Bar Cursor on Upper Sideband Signal at 14.250 kHz
