Don, If you are only interested in CW, why are you including the KDVR3? All the rest sounds OK.
One suggestion that I would offer (because you are not ordering the KRX3 immediately) is to wait on your filters and go with only the stock 2.7 kHz filter for now. Once you have determined what filtering widths work best for your operating style, then you can order the needed filter widths for both your main receiver and the future SubRX. The DSP filters set the ultimate "brick wall" filter width. The roofing filters protect from Hardware AGC pumping from signals in the roofing filter (2.7 kHz) passband which may not be heard unless you widen the DSP filter. So if your initial operation is not heavily oriented to contesting or DX pileups, you will be able to make better filter choices after you become accustomed to the K3. The only other thing you may want to consider is the 2.7 or 2.8 kHz SSB roofing filter. If you think you will in the future want to use diversity reception for SSB, go with the 2.8 MHz filter because it reportedly has zero offset - meaning a future filter purchased should match it. 73, Don W3FPR On 7/4/2012 7:36 PM, Don KB1YBG wrote: > I'm about to place order for k3 kit.
