[Elecraft] K3: Howto install Beta firmware?

[Barry Pfeil]

Hi Ruben.  I recently did this for the first time (having only used the "Production" releases before) and found it difficult to find the instructions on the Elecraft website.  I finally searched the site (using the built-in search function at the bottom left corner of the home page) for "beta" and found  http://www.elecraft.com/K3/k3_beta_release_instructions.htm
 
I never could find a link to this from the main site pages - maybe it's hidden on purpose?
