>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" 73, Eric WA6HHQ ==== (Approx s/n 2362+) From: "Ken Kopp" <[email protected]> Date: Thu, 22 Apr 2010 19:43:41 -0000 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? 73!
