Guy quoted an excerpt from Doug: >>>One other thing: I really wish Wayne and Eric would peal off one of >>>their talented junior engineers and design a K0. (K zero). A single >>>band superhet with 2-3 watts out and super compact. > >What is there not super compact about a KX1?
You have asked me about someone else's (Doug's) statement. You'll need to ask Doug. But I agree. For what it'll do, the KX1 is indeed very small at 1.2 x 5.3 x 3.0 cubic inches. A mono-band DDS rig could be smaller. SWL's DSW was 1.5 x 4 x 4 cubic inches, but its optional case had a lot of extra space that could have been eliminated. If the DSW PCB had used more pre-assembled surface mount (like the MFJ Cub), the package size could have been reduced much more. But more important than the volume figure is the simplicity, compared to the non-simple four-band KX1, that a mono-band rig allows, particularly if the PCB is supplied with most of the common components already pre-assembled using surface mount components. The alignment of a mono-band QRP rig using PIC/DDS technology is also extremely simple. The DSW, for example, requires peaking only one receiver input coil for maximum noise, and adjusting one trimmer cap to set the frequency of the BFO/product detector. All other frequencies are generated by the DDS chip controlled by the PIC's programming (just like the KX1). I could be very content with a KX0-15, in my pipe dream! (No, I don't actually expect that there will ever be such a thing.) 73, Mike / KK5F ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
