During the CQWW RTTY Contest this past weekend, I got the feeling that the K3 receiver could have used some additional RF gain. I was using the 250 Hz filter with +4 dB of I.F. gain dialed in. Switching the preamp on and off produced just a barely perceptible change in the background noise. I seem to remember a previous discussion about the need for a ten-meter preamp, but haven't heard any more about it. Has anyone done a test to see if the minimum detectable signal is up to snuff on 10?
Fifteen meters was better, but still less than what I expected when switching the preamp in and out.
