Stan, The AF1 has a sharp audio filter, and there is no "mute" signal into it, so any tone at the AF1 center frequency should get through.
BUT - the AF1 center frequency must be at the same pitch as your sidetone for that tone to get through the AF1 filter. I suspect that the menu setting for STP on your K2 and KX1 is not the same as the center frequency you have set on the AF1. 73, Don W3FPR On 12/14/2010 5:07 PM, stan levandowski wrote: > I just completed the AF1 kit and it appears to work properly.
