Hi Ray, I don't have a copy of Lyle's original document. One alternative description of the integration of the KPA100 with the KAT100 in an EC2 enclosure is here:
https://ke4rg.blogspot.com/2015/03/assembling-and-using-kpa100kat100-ec2.html I did this integration in 2018 with a KPA100 I built and a KAT100-2 I purchased already built in the EC2 enclosure. It was not difficult and no separate manual was needed to effect it. If your amp/ATU combo was working properly at time of sale, I would connect it to your K2/10 as shown in Alan's (W3DVX) photos: https://wilcoxengineering.com/kpa100-in-ec2/ The internal connections between the KPA100 and KAT100 boards are shown in one of the photos at Alan's web page. Presuming the prior owner of the KPA100/KAT100 did the internal connections properly, the most important external cable is the K2/10 to KAT100 cable. DO NOT use any standard RS-232 cables - this cable must be constructed as described in the manual for the K2. Configuring the K2 to use the KPA100 amp is the same as described in the K2 manual. One must enable the KPA100 in the menu. The ATU must also be enabled in the K2's menu system. Once these steps are performed the entire system operates as a seamless 100 watt transceiver with ATU. If you set the K2 power control to less than 12 watts, the KPA100 is automatically bypassed but the KAT100 remains available as the ATU. 73, Mike, K8CN ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
