[Elecraft] K3 + P3 + Microkeyer

[Don Wilhelm]

An RS-232 A/B switch can make that changeover easy - the common of the 
A/B switch connects to the K3 (or P3) and one side connects to the 
nicroHam while the other side connects directly to a serial port (or USB 
to serial adapter).  A simple "flip of the switch" changes it from 
normal configuration to Firmware download mode.
