[Elecraft] K3S 40M Sensitivity

So, I am a very casual participant in CW SS, usually just enough to get the participation pin. This was going to be interesting using my 2 week old K3S in the contest. I knew there had been some geomagnetic storming and even though the flux was high, I thought conditions could be iffy. As the

Fred Well for the Flex 6000 series you keep one hand on the so called AGC-T control. Since there is no hardware AGC you're doomed to constantly juggling the input level. I had one here and used the Flex Control knob to perform that function. Using it this way brings back memories of Pre-AGC days

Fred, When you have a 24 bit A/D and not looking at the entire spectrum, this should not be as big a problem as you imply, if gain distribution is correct. 24 bits should yield a great enough dynamic range to cover greater than ~ 95% of time; that last ~5% covers your friend next door
