What to do if my ELECRAFT KX2 Transceiver shows HI TEMP warning?
The HI TEMP warning indicates that the PA heat sink temperature has exceeded the safe operating limit. Use DISP to check the power supply voltage, current drain, and PA temperature. Allow the heat sink to cool down, and reduce power if necessary.
What to do if my ELECRAFT KX2 Transceiver displays HI CUR or HI SWR warning?
The HI CUR or HI SWR warning appears when there is low supply voltage and/or a low-impedance antenna load. Check the supply voltage and reduce power if necessary.
How to fix general transmit or receive problems with my ELECRAFT KX2 Transceiver?
A general problem with transmit and/or receive may be caused by low power supply voltage or by a noisy or intermittent supply. Check your power supply’s on/off switch, voltage, fuses (if applicable), and DC cabling.
What to do if my ELECRAFT KX2 won’t turn off?
If the display remains on, or the unit is unresponsive, disconnect the power supply. If an internal battery pack is in use, also remove the battery. Allow 5-10 seconds, then reconnect power and try turning the unit on.
Why is the received signal level too low on my ELECRAFT Transceiver?
The received signal level might be too low due to several reasons: 1. Check headphone and speaker plugs and cables. 2. Make sure that MENU:RX EQ has not been set for large cuts. 3. Verify that MENU:REF CAL is properly adjusted. 4. Make sure MENU:RF GAIN is set to -0 dB.
What to do if my ELECRAFT KX2 won’t turn on?
Check the power cable. If running from an internal battery, make sure it’s charged.
How to troubleshoot general firmware behavior issues on my ELECRAFT KX2 Transceiver?
To troubleshoot general firmware behavior issues: 1. Check all menu settings. Hold MENU for about 3 seconds to see help information about each menu entry. 2. Try loading the latest KX2 firmware. Review the release notes for changes that may be related to your symptoms.
Why does the VFO A frequency change by itself on my ELECRAFT Transceiver?
If using a mic other than the MH3, set MIC BTN to OFF.
Why can’t I transmit in CW mode on my ELECRAFT KX2?
If you cannot transmit in CW mode: 1. Make sure the key or keyer paddle is plugged into the correct jack. 2. To transmit immediately upon hitting the key, you must have VOX-CW enabled. If VOX is off (PTT-CW), you must tap XMIT before sending; otherwise only a sidetone is generated. 3. You may be in SPLIT mode, with VFO B set for a voice or data mode. Tap A/B to check VFO B’s mode.
Why can’t I use the mic in voice modes on my ELECRAFT KX2?
