I can use panadapter to watch for band openings and tune to the signals. In more crude form you can use scanning and CW decoder to "hunt". Skimmer just takes it to another level, just like computer logging to paper logging. The key here is ASSISTANCE by other persons via other means. Not the gadget and software in my shack, that is tool just like anything else in my shack. Ruling by CQ CC to put skimmer into assisted is the dumbest and contrary to logic.

Kevin Stover > ACØH > The assisted categories were created to capture the ASSISTANCE by SOMEONE else, another operator via other means, packet, telephone, internet. Skimmer is another GADGET in operator's shack, using his equipment, antennas etc. just like any other gadget in the shack. We are technical sport using technology gadgets and operator skills. Classifying gadget, skimmer as (human) assistant is the example of twisted logic. Besides, skimmers would eleviate problem of packet pileups (which sucks) as individual skimmers, using individual antennas and setups would come across the "juicy" ones and flag them to operator, spreading the pileups. Mybe we should go back and classify everything besides spark gap and hand key as "assistants"?? 73 Yuri, K3BU.us __ 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
Re: [Elecraft] K3 and the subreceiver (fixed)
ooops, sorry about the formatting, here it is again. Note on diversity reception. Way back in early 70ies while using two Drake R4C receivers for contesting, I discovered interesting effect. When using two receivers, L & R, going to two ears L & R, using different antennas - Beverages and Inv Vee, I would come across situations when I can hear weak station using both ears/RXs, but when switching to individual one, signal would not be there. It looked to me like some kind of noise canceling, perhaps in combination with brain processing. Diversity can be with polarization, angles, directions. Having tracking receivers makes it sooo cool. Recently while operating as TF4X in CQ 160 CW while using K3 and array of Beverages, Rhombics and Arctic King (TF4M.com) this again came very handy in digging out the weak ones. Noise floor there was just at about 0 and it was some experience to hear the world, being on the top of the world. K3 is unique in using two RX diversity reception, especially for serious contesting, and when limited with 13 lbs weight limit in carry on luggage - jus' one honey of the radio. Packaging, modularity, circuit design and performance is leaving just about all of my "big boxes" in the dust. Congrats and thanks Elecraft!
