I see a little odd symmetry here, between a local interference case (my QTH) and contesting with the K3.
Incidentally, I get same complaints on CW and SSB. Can't hear them, but their radios have such poor filtering or selectivity that my TX is wrecking what they receive, when close to their freq. And that's without the crowded contest environment, a majority of the time. There's also a local ham with "clockwise syndrome", who runs way too much power to make sure he amplifies the splatter. He has off-frequency energy and gets into the K3 from many KHz away. I've complained to him numerous times about wasting energy by blasting it all over the spectrum, etc. No argument works with this guy. Showing him a spectrum plot of his signal from an 8656B didn't help - he said my spectrum analyzer was defective, despite same-band same strength signals looking different and narrower than his. Maybe he'd believe a P3 plot? So we can have the problem both ways. The K3 can hear gudge thrown off by improperly set up TX, and it can't hear nearby signals with TX run correctly, because it's designed for this. This sort of thing happens when a revolutionary breakthrough happens in most infrastructure. The yesteryear equipment and today's SOTA eqmt aren't compatible any more. That's an extreme statement, because we should consider our neighbors (we K3'ers). Just the same the neighbors probably won't consider anyone but themselves. This is how it has always been, imho, for some special privileged class of ham. SIC. And we don't have to act like that, because most ops want to be the best - and that isn't just a technical factor. Now, if everyone just threw in the towel on the old equipment and bought K3's we would all be compatible again. I neglected to ask Wayne or Eric when their sales forecasts projected this to happen, but it might be a few more years..... This same topic has come up on the list many times, so that means the problem cited has occurred many times more than that. If we just think of others using inferior equipment on HF for RX, we might operate a little differently. Think of someone using a Hammarlund receiver ca. 1945 with no crystal filtering at all, and just a BFO to make sideband usable. Maybe there should be separate band segments for K3-only operation? :) 73, matt W6NIA K3 #24 K2 #2810 On Tue, 01 Dec 2009 06:02:43 -0800 (PST), you wrote: > > > > > > > > > > > > > >That is exactly what's happening to me daily but on SSB,guys with poor >selectivity radios about 3Khz from me come to my freq to complain I am >bothering them and honestly I don't hear a thing even at 3Khz and with 30db >over 9 signal,when I go to CW I can be at just 300Hz away from a 599 signal >and still be able to pull a 559 signal with the 500Hz roofer and the DSP >dialed to 200Hz,this radio has an amazing selectivity no doubt about it. > >AD4C > > >"For a refined ham it is compulsory to own a k3" > >--- On Tue, 12/1/09, Dyarnes <w7...@cox.net> wrote: > > >From: Dyarnes <w7...@cox.net> >Subject: Re: [Elecraft] K3 in the CQWW contest >To: "Jim Brown" <j...@audiosystemsgroup.com>, "Elecraft Reflector" ><elecraft@mailman.qth.net> >Date: Tuesday, December 1, 2009, 4:09 AM > > >That's an excellent point Jim!
