I'm just curious how others are using (or not using) the K3's pre-amp. I have found few, if any, situations where I felt the pre-amp really improved a signal vs. the additional noise that is associated with turning on the pre-amp. It takes a lot of balancing, in my view, between the RF gain and the AF gain to enhance a weaker signal, and I don't find the pre-amp to be all that helpful. Having said that, I'm pretty happy with the results I get w/o using the pre-amp. Also, signals on the K3 w/o pre-amp compare very favorably to signals on my Orion II with the pre-amp on. The K3 still seems to hear just a tad bit better. So, I'm wondering if I'm missing some other trick or setting that would make the K3's pre-amp more beneficial. I can tell you that 90% or more of the time I tend to have my RF gain at 50% or less (at about 12 o'clock), and make very slight adjustments of the RF gain from there. I suppose much of this might depend on one's noise floor. FWIW, mine is about S4.
