K4 Highlights #3: DX LIST mini-app

No doubt many K4 ops have an encyclopedic knowledge of DX entities -- every prefix, whether countries or territories still exist, whether you can get there without military or divine intervention, etc. 

For the rest of us, there's the K4's built-in DX list. This is an Elecraft-curated list, cross-checked against several other reputable sources. 

The next time you hear a "new one" on the air, try popping up the K4's DX list rather than scouring the internet or rooting through piles to find that ARRL reference you ordered in 1972. Ours is right there at your fingertips.

Steps:

1. Tap Fn.
2. Tap DX LIST.
3. Scroll the list with VFO A or the up/down arrows, or...
   tap the magnifying glass icon to do a text search. 

If more than one hit is found during a text search, the up/down arrows go into hit-navigation mode, as indicated by the magnifying glass reversing colors. This allows you to jump from one match to the next quickly, without scrolling. 

This navigation technique is used in other cases as well. In fact, the DX LIST feature is just one example of a mini-app running on the internal Linux module. Others include the software updater and the built-in owner's manual. With virtually unlimited code space, we'll be adding other mini-apps in future releases.

Important Notes:

1. Please let us know if something is missing from the DX LIST or is inaccurate. We try to stay up to date, but "DX entity" is still a moving target even in the 21st century.

2. If you see a large, flashing, red asterisk next to a prefix, it's one I haven't worked yet. Please contact me straight away!
