As I was contacted by a few HAMs where to get “my” box I would like to give you a little parts-overview. Unfortunately I`m not able to manufacture this box in a higher quantity so you will have to build it yourself. All the necessary stuff was purchased in european online-shops but for sure you will be able to find the same or equal parts in the U.S.
Watch some portable KX3 pics our
This box weighs 1,6 kg = 3,5 lbs – including the components listed below (except the charger) AND the KX3 with its ATU- and filter-option installed (no internal batteries) and a light weight (iphone) headset. My buddipole dipole antenna system weighs 2 kg = 4,4 lbs on top.

- Some velcro between the KX3 and the box can give additional support.
- I used a textile tape at the inner edges of the big cutout not to scratch the KX3 😉
- HB9TVK made his own box!
- UPDATE 02/2014: I´ve added a BNC connector between the status switch and the ACC1 for a 2m antenna. A PTT push button has been built in as well (using ACC2).
- DK6AH made his own box!
- AK5SD made his own box!

Have fun and build your own solution to go portable! Comments appreciated!
