They're independent. Since the KAT3 tuner is just a plug-in, I'd suggest installing it and the KPA3 shield first (do everything in the KPA3 instructions down to "Installing the KPAIO3A Interface Module"), since the both require more mechanical disassembly. Put everything back except for the K3 top cover and check out the KAT3 at 10 watts (don't forget to enable the KAT3 as described on the last page of the installation instructions!).
Then it's a matter of replacing the blank panel on the K3 with the fans and then plugging in the KIO3A and KPA3 100 watt amp modules and testing and enabling them. 73 Ron AC7AC -----Original Message----- From: Elecraft [mailto:[email protected]] On Behalf Of Gary Smith Sent: Wednesday, February 17, 2016 1:12 PM To: [email protected] Subject: [Elecraft] Amp or tuner / Chicken or Egg Just got my factory assembled K3s/10 delivered. I need to install the 100W amp and internal tuner. Seems like I'd want to install the amp first. Yes?
