Hello Susan: You got a lot of good responses. One way to quantify the receiver performance is to use a signal generator with a known output level and see if it produces the expected signal in the receiver. Elecraft has a little one (XG3) that fits in the palm of your hand that will check your K3 on 3 bands. If it's good there, it's likely good everywhere, Hi! Alternatively you can use the little wide-band noise generator they have for all bands. I don't believe its output is calibrated but if you can establish that the K3 is working properly and log what noise level it produces on all bands, its a simple matter to run the check in the future of you're curious.
If you are again on the high seas, you may find the noise levels are astonishingly low at certain times, allowing you to hear signals that are normally buried. I used to love SWL-ing when well offshore with the regen receivers most older radio consoles used as the emergency rx. Signals from all over the world jumped right out of an almost non-existent noise level. And then a squall line shows up and the cans get blown off my ears, Hi! Even moored in port you may have a better noise environment than 99% of us ashore.

It seems that most signals I hear are rather weak....is it that the K3 is now allowing me to :hear: signals I didn't before?, OR is it that something is deficient? Susan If you don't change direction you WILL arrive exactly where you're headed!!
