I've never been floored by the K2's sensitivity. I've done the test you mention, though probably not as thoroughly. When plugging in an antenna, I do hear the noise floor come up. Sometimes I have to crank the AF gain to hear it but it happens. I figure above 20 meters, that's what the preamp is for so I've never really troubled myself with it.
Also, given the current state of the sunspot cycle, I've been on 80, 40, 30 and some 20 meters and that's about it. Even on 20, I find the rig acts deaf although I know it does hear fine. That AGC action is different than other rigs I've had so the K2 acts differently. - Keith N1AS - - K2 5411.ssb.100 - -----Original Message----- From: Paul Del Negro I'd like to put something out here and see if others experience the same thing or if I possibly have a problem with my K2 sn5834. ... check for an increase in noise level when switching from a dummy load to a resonant antenna on a dead band (like 10m is lately) _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
