[Elecraft] K3 shipping info

I just saw this on the Elecraft site. "Newly received K3 orders are now delivered approximately 1.50002 months (or less) after order date." It seems to me that the number of months is a little too precise to be realistic. LOL Nelson - K8DJC K3 #560 -- I am using the free version of S

[Elecraft] K3: power setting by mode?

Just wondering if it would be a SMOC to add the ability to store the power setting by operating mode, in the same fashion it's currently done by band (i.e. config option). I have caught myself calling CQ on PSK-31 at 100w a couple times already... Steve AD7OG __

[Elecraft] K3 Interface

Hello all, I've added some more convenience to K3 operation, how about seeing the DSP bandwidth without pressing any buttons? That's new. Also added one click selection at .1, .5, 1, 1.8, 2.4, 3.3, 4.0, and 6.0 khz DSP bandwith. One click band stacking and analog S-Meter remain standard. Photo

Thank you Lyle. It never occurred to me that this was purposeful. I adjusted the filter offsets with the 500 and 200hz filters to more closely "center" them. Guess I'll believe the factory settings from now on! tnx, Gary W7TEA This asymmetry is due to the way in which the K3 aligns the roof

Re: [Elecraft] [K3] Questions about ARRL review

Hi Lyle, If you look at the larger values of attenuation (134 vs 115, or 113 vs 93) the result is mostly due to the difference in shape factor of the roofing filter. Expressed differently, an 8-pole filter is likely to have a steeper slope in its selectivity curve than a 5-pole filter. But
