Alignment and Test
Initial Test

Turn on the K2. If you see I N F O 0 8 0 or the receiver is muted, refer to Troubleshooting.

Enter the K2 menu by tapping M E N U . Tap D I S P L AY to switch to the secondary menu (you'll see
S E C on the display). Then locate the D 1 9 menu entry using B AN D + / B AN D - or the VFO knob.

Edit the D 1 9 menu entry by holding E D I T . Use B AN D + or B AN D - to set D 1 9 to Y (meaning
yes, D19 and D20 are installed). Exit the menu by tapping M E N U twice.

Use B AN D + and B AN D - to switch to the 60-meter band, which should appear between 80 and 40
meters. (If a band does not appear between 80 and 40 meters, see Troubleshooting.)

Due to recent firmware changes, the frequency of this band may initially be set to something other than
the 5 MHz range. If so, use direct frequency entry to enter a frequency of 5000 kHz for VFO A. To do
direct frequency entry, hold
B A N D + and B A N D - together until you see "- - - - " on the LCD, then enter
5 0 0 0 using the numeric keys on the right side of the front panel. Then copy VFO A to VFO B by
tapping A= B .

You should now be able to tune the 60-meter band using the VFO knob. If not, see Troubleshooting.
40 / 60 Meter Alignment

Connect the (+) lead of a DMM (digital multimeter) to the lead of R30 nearest the case side panel (R30
is in the synthesizer area of the K2 RF board). Use a small alligator clip to ensure a good connection.
Connect the (-) lead to one of the ground jumpers on the RF board. Set the DMM for to measure DC volts,
10 V or higher full-scale.

Switch to 40 meters. Set the VFO first to 7000, then 7300 kHz, noting the DMM's voltage readings at
each frequency. Switch to 60 meters and perform the same test at 5300 and 5450 kHz.

If any of the above readings are below 1.0 V or above 7.5 V, you'll need to re-adjust the VCO inductor,
L30, as explained under VCO Alignment in the Alignment and Test, Part II section of the K2 Owner's
Manual. Note: Add 60 m (and 160 m, if applicable) to the list of bands shown in Table 6-1, and use 1.0 V
as the minimum, not 1.5 V. If you're unable to find an acceptable setting for L30, see Troubleshooting.

Connect an antenna to the K2. While listening to and noise or a weak signal, use a small flat-blade
screwdriver to peak the two trimmer capacitors on the K60XV module (C1 and C2). The screwdriver used
can have a metal handle since the rotors of the trimmers are grounded.

Connect a dummy load to the K2. Set the POWER control about 2 watts.

Enter T U N E mode, then adjust the two trimmers for maximum transmit output. Cancel TUNE.

Set POWER to 10 watts. Verify that you can reach this level in TUNE mode on both 40 and 60 m.

Re-install the top cover or KPA100 module, re-connecting all of the internal connectors. Secure it with
six screws. If you're re-installing a KPA100, be careful not to overtighten the side-panel screws.
