KXUSBC2 installed into KX2

13 May: Updated info, including notes from its designer, Manuel HB9DQM. 

I received my KXUSBC2 in the mail today and wasted no time installing it into my KX2.

No soldering or de-soldering was required. Other KX2's may or may not require a small amount of soldering, depending on when the it was manufactured.

Those contemplating the addition of the USB-C charger to their KX2 should read the instructions here

If you're replacing Elecraft's built-in charger, the KXUSBC2 retains Real-Time Clock functionality. 

Advantages over the Elecraft KXIBC2 charger for the KX2:

  • Ability to charge KX2 from what you already have - a generic USB-C cable, via automobile jack, power bank or wall plug
  • Contains several configurable options
  • Allows KX2's battery to act as an "emergency power bank" for a dead cell phone, etc
  • Almost half the price of Elecraft's charger!

The installation was simple and took no longer than 15 minutes.

    1. Hi Scott - it certainly adds more versatility to the radio and doesn't take anything from it. The original coaxial DC jack still works as before. Now I have a KXIBC2 to get rid of...

  2. Now THAT is a useful mod! I sold my KX2 in 2019 but if I still had it this would be a no brainer.
