Stuart, this noise discussion takes me back to the days of my National HRO-5TA1. Single conversion and no roofing filters. Wonderful old radio - for its time. It was 1947 if I remember when I got it,

True, Bob, but at HF the receiver noise figure is largely irrelevant as band noise usually totally overwhelms front-end noise. I think that others have made the point that what the receiver *does* wi

Thanks for the quotes, Tim. Just the added thought that the filters, both IF and audio, on the K2 are not all that sharp compared to the PRO DSP filters. Also, the K2 has quite a noticeable roll-off
