[Elecraft] Using K3 (or KX3) Macros for custom SPLIT functions

[Wayne Burdick]

For those who may have missed this when I first described it--

In a recent discussion about SPLIT, many proposals were made (too  
many :)  Others argued for no change.

With this in mind, we've created a new "switch macro" feature. It  
allows you to create your own variation on SPLIT -- or any other radio  
function -- and execute it with a single switch press. In effect,  
you'll be creating your own custom firmware for the K3 that automates  
control sequences you use most.

Example #1 (SPLIT+2):

   A>B
   A>B
   SPLIT
   VFO B up 2
   RIT and XIT off

Example #2 (WEAKSIG):

   Sub ON
   Diversity mode
   main/sub preamps on
   200-Hz bandwidth
   center passband

Many other combinations are possible, limited only by the K3's remote- 
control command set and the macro length limit (presently 56 bytes).  
You'll be able to set VFO frequencies or RIT/XIT offsets, adjust gain  
or filter controls, and virtually "tap" or "hold" nearly any control  
on the radio.

First, you enter a sequence of K3 control commands into one or more  
macros using K3 Utility, which can store them in the K3's EEPROM.  
Next, you assign the macros to any of the K3's 10 programmable  
function switches (PF1, PF2, M1-M4 tap, or M1-M4 hold) using the new  
MACRO menu entry.

After that, activating the switch will perform the desired functions,  
and the name of the macro will flash on VFO B as a reminder (e.g.,  
"SPLIT+2").

Many K3 (and KX3) owners are using such macros to obtain exactly the splits that they prefer.
