Hello Todd! > ... I built and added the KAT100 to the EC2 yesterday and now I > don't seem to have any room for adding the speaker jack on the EC2. I use the speaker in the K2 for now, although you could modify the KPA100 speaker jack wiring to use the double male patch cord you mentioned. Just solder a jumper wire at KPA100 J6 pins 1 and 2 to defeat the cutout switch. 73, Lyle KK7P
