ELECRAFT 101
RS232 Interface Setup (PORT)
Use the P O R T menu entry to turn on 4800-baud RS232
communication. When P O R T is O N , tapping
D I S P L A Y sends an
"FA" command (VFO A frequency) for test purposes. Refer to the
KIO2 or KPA100 manual for details.
SPLIT/RIT/XIT Configuration (SPLT)
Normally, the K2's S P L I T , R I T , and X I T selections stay the same
as you switch from one band to the next. To have these selections
stored on a per-band basis and retained when power is off, set
S P L T to P E R (per-band).
10 and 12 m Power Limit in SSB/RTTY Modes (Po28)
The highest distortion-free single-sideband power output level may
be less than 15 watts, especially on 10 and 12 m. We recommend
leaving P o 2 8 at 1 0 . 0 watts. (Does not apply to CW mode.)
RTTY/Data Mode (RTTY)
RTTY/Data mode (mode letter lower-case r ), if enabled, provides
four independent crystal filter settings for use with data modes. To
enable RTTY/Data mode, set the R T T Y menu parameter to O N .
The
M O D E list will then include C , L , U and r . r -NORMAL mode
uses lower sideband, and r -REVERSE (with a "bar" over the r ) uses
upper sideband. To select r -REVERSE, hold the
C W R V switch.
(FINE RIT is also very useful in data modes; see page 99).
Filter configuration (C A L F I L ): r mode defaults to the same
settings as LSB and USB. Use C A L F I L (on 17 meters or below) to
modify the r -mode filter bandwidths or BFO settings as needed.
Speech compression (S S B C r ): The S S B C menu entry will
change to S S B C r when r mode is selected. A setting of 1 - 1 (1:1,
or speech compression off) is recommended for RTTY/data.
Real-Time Clock (RTC)
If the KAF2 option is installed, the D I S P L A Y switch will show time
or date. Refer to the KAF2 option manual.
RIT/XIT Range Selection (RIT)
R I T is used to select one of four RIT/XIT OFFSET ranges. If the
selected range is +/- 1 . 2 kHz or higher, the RIT/XIT annunciators
flash whenever
R I T or X I T are turned on.
Accessory Outputs (ACC)
This menu entry is reserved for use with a future programmable-I/O
accessory.
Extended VFO Range (D19)
Leave D 1 9 set to the default, n (no), unless you have installed
varactor diodes D19 and D20 in conjunction with the K60XV
option (60 meters plus low-level transverter I/O). At that time the
parameter should be set to Y .
Note: Do not install D19 and D20 without the K60XV, even if
they were supplied with your K2 kit.
K2/100 Mode Selection (PA)
If you have the KPA100 option installed, the P A menu entry
shows the 100-watt stage's operating mode. While editing the P A
parameter, tapping
D I S P L A Y selects the fan mode (n o r , L o H i ,
H i ). For more details, refer to the KPA100 manual (Appendix G of
the K2 owner's manual, which is supplied with the KPA100 kit).
