[Elecraft] K3 switch macro update

[Wayne Burdick]

I'd like to thank everyone who's been testing the K3's new macro  
feature. It appears to be working as intended, allowing operators to  
customize SPLIT and other operations as needed.

We'll be doubling the number of macros (from 4 to 8) and increasing  
their length from 56 to 120 bytes. This will allow you to do things  
like "SPLIT+2" and set up the sub-receiver with a single switch press.

The K3 Programmer's Reference now has complete instructions for  
creating and using macros, along with updated examples. The latest  
revision (C4) can be found here:

We hope to have beta releases of K3 firmware and K3 Utility with this  
feature by tomorrow.

73,
