ELECRAFT K2 - Page 9

Alignment and Test, Part III
In this section you’ll complete alignment and test of the K2 on all
bands.
Make sure the power switch, S1, is in the OFF position (out).
Connect your power supply or battery. For transmitter tests, a
battery or well-regulated power supply that can handle at least 2
amps is recommended. Avoid using a switching power supply
unless
it is well shielded and includes EMI filtering. A linear-mode
supply
will typically generate much less noise in the HF bands. (See any
recent ARRL Handbook for examples of both types.)
Connect a 50-ohm dummy load to the antenna jack. The
dummy load should be rated at 10 watts or higher.
Connect a pair of headphones and a key or keyer paddle.
Set the POWER control fully counter-clockwise (minimum
power output).
Turn on the K2. You should see
ELECRAFT
on the LCD,
followed by the frequency display.
Select voltage/current display mode by tapping
DISPLAY
to
make sure the receiver is not drawing excess current. (Typical
current drain will be 180-250 mA depending on menu settings.)
Return to frequency display mode.
Switch to CW and select FL1 using
XFIL
.
Use the menu to set up the desired CW sidetone volume and
pitch if you have not already done so, using
ST L
and
ST P
.
The
pitch can be set from 400 to 800 Hz, although 500-600 Hz is
recommended. The sidetone volume and tone will vary a small
amount as the pitch is changed, but it should have a pleasant
sinewave sound at any setting.
Set up the desired keying device using
INP
. If you’re using a
hand key or external keyer, use
INP HAND
. To use the internal
keyer, select
PDL n
or
PDL r
(normal or reverse paddle).
You can also connect a computer or external keyer along with
the keyer
paddle. Refer to the Operation section for details on this
"autodetect"
feature (Page 92).
To verify that the sidetone is functioning, hold the SPOT
switch.
Tap any switch to turn the SPOT tone off.
