to about 2 hours with no power supply or battery connected. This capability is
provided by a supercapacitor on the KXIO2 module (see pg. 7).
The KXIO2 also provides two open-drain signals on its AUX jack. These could be
used for antenna switching or other applications. See the AUX 1 and AUX 2 menu
entries.
In the case where the LCD backlight is turned OFF, this menu entry adjusts
brightness of the discrete LEDs (TX, delta-F, OFS, and VFO B LED). Does not set
brightness of the LCD backlight itself (for that adjustment, use BKLIGHT).
When using the KX2 hand-held, or if operating time is very limited, logging may
be inconvenient. The KX2 can capture up to 2048 transmitted characters, along
with time, band, and mode, so you can update a paper or electronic logbook later
on. To enable logging, set this menu entry to ON. Logging applies to CW (C),
PSK-D (P) and FSK-D (F) modes, and only when using the internal keyer.
To take advantage of time stamping, either set the time on every power-up of the
KX2 (MENU:TIME), or install the KXIO2 option module (see Options).
When logging is enabled and there’s room available, the DVR icon (above the S-
meter) flashes slowly. Outgoing text decode is turned on, allowing you to make
sure you’ve sent call signs accurately. If you fill the log, LOG FULL is flashed.
To review log text, tap DISP and use VFO B to find the LOG display. The VFO A
knob can then be used to scroll. Time/mode/band (MHz) are shown on VFO A
(e.g., “0023 C14”); text is shown on VFO B. Holding CLR erases the entire log. To
“dump” the log, send “LG;” to the KX2 via KX2 Utility’s Command Tester screen.
Tips: To conserve space, use message buffers (MSG) to send CQs, name/QTH,
etc. Messages are recorded in the log. To start/stop logging quickly, assign
MENU:LOGGING to a programmable function switch (PF1-PF4).
