Andrew, Bypass is not "OFF", so yes it could still be in-circuit. The only way to really find out is to re-install it and set everything to default. A good exercise for a rainy/snowy afternoon. 73, Don W3FPR On 2/19/2022 9:04 PM, Andrew Moore wrote: Hi Don - thanks for the suggestion. Any

Hi Elecrafters - Today I took delivery of K2 #892 and very happy to have it in the shack after selling my #4958, I think it was, years ago... if anyone has it I'd like it back please). This #892 has a "static sounding" scratchy/raspy noise on top of CW signals. It sounds similar to what you'd
