What does it mean when an asterisk (*) appears in the PWR setting display on my ELECRAFT KX2 Transceiver?
An asterisk (*) in the PWR setting display (e.g. 5.0 W*) indicates that Transmit ALC has been turned off. To turn it back on, go to MENU:TX GAIN, unlock the parameter by holding FREQ for 3 seconds, then tap ATU.
Why does the VFO A frequency not change on my ELECRAFT Transceiver?
The VFO may be locked. Tap RATE to unlock it.
What to do if I experience low power output on my ELECRAFT Transceiver?
Low power output may be due to a high-SWR load and/or low supply voltage. Also, try redoing Transmit Gain calibration.
What to do if the display backlight turns on, but then turns off upon release of switches on my ELECRAFT KX2 Transceiver?
Disconnect all external equipment from the KX2. Verify the power supply or battery voltage is between 8 and 15 V.
What does BAT LOW flashing periodically mean on my ELECRAFT KX2?
When BAT LOW is flashed periodically, check the battery voltage by tapping DISP and rotating OFS/B until the supply voltage display appears. If the batteries are at their normal voltage, you may have MENU:BAT MIN set to the wrong low-battery warning level. See this menu entry for recommendations.
