Default Frequency Memories: When you first turn on the K2,
each band memory is preset as follows:
• VFO A is set to the first multiple of 100 kHz above the band
edge (e.g. 7100, 24900).
• VFO B is set to the U.S. CW QRP frequency for that band
• Other defaults include: CW mode; VFO A; fast AGC; preamp
ON above 40 meters and OFF on 40 m and below; noise blanker
OFF and high threshold; antenna 2 OFF (antenna 1 selected);
receive antenna OFF (normal receive operation)
Memories #1-8 are preset to the same values as the 160-10 meter
band memories, respectively.
Store and Recall: Ten memories are provided, numbered 0
through 9. Each memory stores the same information that is stored
per-band.
To store the current setup in a frequency memory, hold
S T O R E
until you see E N T 0 - 9 , then tap one of the numeric keypad
switches. To recall a stored setup, hold
R C L until you see E N T 0 -
9 , then tap the number of the memory you wish to recall. In both
cases you can cancel the operation by tapping any non-numeric
switch.
Note: If you hold rather than tap a numeric keypad digit when
doing either a store or recall, you will initiate scanning. (See page
96.)
Direct Frequency Entry: To do direct frequency entry, hold both
B A N D + and B A N D - simultaneously. When you see "-----" on the
LCD, release the two switches, then enter the target frequency
using the numeric keypad. To enter a frequency in the 160 meter
band, you must enter 5 digits, starting with a leading 0, e.g.
0 1 8 3
5 . For other bands below 10 MHz, you need only enter 4 digits
(e.g.,
7 0 4 0 ). On transverter bands, direct frequency entry can
only be used to go to a new frequency within the present band. (see
T R N x menu entry, page 102).
There are three possible results from using direct frequency entry:
• If you enter a frequency within the current band, only the
current VFO will be updated.
• If you enter a frequency that is in a different band, a band
change results, and the entire configuration for the target band
will be loaded, except that the current VFO will now be at the
frequency you just entered.
• If you enter a frequency that is too far outside any available
band, you’ll be switched to the closest available band, and the
frequency will be set to the one last used on that band. For
example, if you try to switch to 8400 kHz--which is typically
outside the range of the synthesizer--the K2 will switch to 40
meters and setup the VFOs as they last were on this band.
Tuning Rates: The VFO tuning rate is selected by tapping
R A T E .
Default tuning rates include 10 Hz, 50 Hz, and 1 kHz per step,
resulting in 1 kHz, 5 kHz, and 100 kHz per VFO knob turn. Other
tuning rates can be selected; see the R A T E S menu entry (page
100).
The frequency display changes to remind you of the current tuning
rate. At 10 Hz/step, two decimal places are shown (100 Hz and 10
Hz). When you select 50 Hz/step, the 10 Hz digit is blank. When
you select 1 kHz/step, both decimal places are blank.
VFO Lock: The current VFO frequency can be locked by holding
the
L O C K switch until L O C is displayed. The decimal point will
then flash slowly as a reminder. Split Operation: Lock applies
only to the current (receive) VFO. So, while you are holding the
R E V switch (temporary VFO reverse), you can change the
frequency of the other VFO (transmit), overriding lock. This is
very useful when operating SPLIT, since it allows you to check and
modify your transmit frequency without unlocking the receive
VFO.
Holding the switch again cancels lock and displays N O R (normal).
