[Elecraft] How to use external ALC with the K3

[Doug Faunt N6TQS +1-510-655-8604]

>From Eric, yesterday:

You will need the mod. 

This change was included on All K3s shipped on
Dec 10, 2008 and later. (Rev B KIO3 Digital board) 

See: http://www.elecraft.com/K3/k3_app_notes.htm and scroll down to:
"K3 Negative ALC and Ext Band Data Pull-up Mods, Rev B: REMIOUPGD"

   I understand the K3 presently is configured for "positive going"
   ALC.  I know there is a mod kit available to change this to a 
   "negative-going" ALC, and there probably are a number of K3's
   that have been changed. 

   How will the KPA500's ALC be configured?
