[Elecraft] Firmware

[Don Wilhelm]

To the best of my knowledge, there are no firmware upgrades that require 
hardware changes.  The firmware is written to figure out which version 
to load - an example is the old and the new DSP board - but that was 
long ago.

The converse is NOT true - some hardware changes require firmware 
upgrades to make them functional.
