FAQ

A: The KX2 uses our KXBT2 internal battery option, a fully sealed and electronically protected lithium-ion battery pack. The KXBT2 can be plugged in either internally or externally to the transceiver. It is fitted with a 2.1mm ID/5.5mm OD plug. The pack is installed in the KX2 by opening the bottom cover as shown in the next illustration.

A: Yes: The KXIBC2. This internal charger works with or without the KX2 turned on, generates no RFI, and includes the same real-time clock functions as the KXIO2. It can charge the internal battery from any small external power supply, battery, or solar panel. For a full charge, the external source should provide 13.5 to 15.0 V, though voltages as low as 12 V can provide a useful amount of recharge.

A: No. Elecraft provides a complete solution for using and recharging the KXBT2. Specific voltage, current, and temperature limits are enforced to ensure safe operation. We do not recommend alternative methods of recharging the KXBT2.

A: No. The KXBT2 Charger can only be used to recharge a KXBT2 that has been removed from the KX2. For longer outings, you may wish to bring a spare battery pack.

A: No. The dimensions of the KXBT2 will not allow it to fit inside the KX3, even if its AA battery holders are removed. The KXBT2 can, however, be connected to a KX3 externally and will operate the KX3 at up to 10 W output. The KXBT2 will also power most devices rated for 9 to 15 volts, including our other small transceivers, PX3 (matching panadapter for the KX3), and XG3 signal generator.
