Ken and Don, Yeah, you guys are right again. I missed the 1% and didn't look at the blue ones. It looks like r23 gets installed later. So far so good with the KDSP2, KIO2, and KAT100. I was using the elecraft control program last nite controlling the rig. Cool! The amp is a little more complicated, but I am taking my time. Thanks for the help. Steve, W2MY
