Tom, et al. Boy, does THAT make a difference... Yup, AF GAIN was set on LO. Now things are about right at 10 o'clock w/o NR and 11 o'clock with NR.
(Now the Aptos gang needs to implement the same configuration option on the K2...) I guess the fact that I haven't taken the time to really familiarize myself with the K3 is showing. I figured out how to change B/W and centering of filters, set power level, interface with computer for logging and key an amp. Then off to enjoying the new radio. I bought a Kenwood mike to use with it, but have yet to plug it in. Biggest unresolved problem so far: the K3 is too light. Slides back when I put in the headphone plug! Oh, I like the NR on the K3. Level one is at least as good as on the OmniVI. I seldom drop down to really narrow bandwidths, preferring about 800 to 1000 Hz B/W. I have yet to use it in a contest, though. (Used the OmniVI for SS last fall) Thanks, guys K7GT On Tue, Apr 28, 2009 at 9:47 AM, Radio Amateur N5GE <n...@n5ge.com> wrote: > On Tue, 28 Apr 2009 08:52:52 -0700, Allan Taylor <k7gt...@gmail.com> > wrote: > > Allan, > > When you have the sub RX and Main RX both turned on there will be a > 3dB reduction in signal strength (and Volume) due to the combiner that > combines the two signals.
