Tips for CW Operation
All
of
the
tips
for
SSB
operation
apply
equally to CW reception, with a few important
additions.
For
automatic
transmit/receive
switching, the VOX must be switched on.
When tuning around the bands, wider IF sel-
ectivity (NAR switch off) allows you to hear
more signals at one time, often making tuning
easier.
However, when you find a station you
wish to listen to (or call), press the NAR
switch, to cut out nearby signals and decrease
noise.
To avoid loosing the desired signal
you must tune so that the pitch of his signal
is near the center of the passband, which you
set with the PITCH selector.
To check it, set
the DRIVE
control
to minimum
(to avoid
creating QRM), and close the key.
Tune the
receiver so that the pitch of the desired sig-
nal matches the sidetone (if you want to zero-
beat).
Then press the NAR switch.
After selecting the narrow IF filter, you can
also activate the APF, for extra-narrowband
selectivity (there is little point using the
APF without the NAR switch on).
This is most
practical if you have first preset the APF
frequency to the sidetone:
(1) Press the MARK button on the rear panel
to activate the marker generator, and
press FULL BK-IN to activate QSK.
(2) Set the DRIVE control to minimum, and
squeeze the keyer paddles.
Tune the
receiver for a heterodyne of the same
pitch on the nearest 25 kHz marker.
(3)
Turn
on the APF,
and adjust the control
for peak
on the heterodyne:
now
note
the precise setting of the APF control.
(4)
Turn off the APF and MARK
switches, and
advance
the DRIVE
control.
Now, whenever you tune a signal to the same
pitch as your sidetone,
just hit the APF
switch - only slight adjustment of the APF
control may be needed.
Handling interference on CW is similar to SSB:
both SHIFT and NOTCH are even more effective -
the NOTCH filter can be used to suppress CW
signals on nearby frequencies.
If using the internal electronic keyer, adjust
the KEYER speed control while squeezing the
keyer paddles (generating -——.—).
Make sure
the DRIVE control is at minimum (counterclock-
wise) when you do this.
