Hi,
Any advise about operating skills for the next weekend overcrowded band's? how do you avoid splatters from very close station? 73 de Manolo EA7LL ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |
Preamp OFF, except on 10 and 15 meters.
Attenuator ON for 40, 80, 160 meters. NB, NR OFF High cut = 2.05 Dave Hachadorian, K6LL Yuma, AZ ----- Original Message ----- From: "Manuel Pareja" <[hidden email]> To: <[hidden email]> Sent: Tuesday, October 20, 2009 7:48 PM Subject: [Elecraft] contest > Hi, > > Any advise about operating skills for the next weekend > overcrowded band's? > how do you avoid splatters from very close station? > > 73 de Manolo EA7LL > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:[hidden email] > > This list hosted by: http://www.qsl.net > Please help support this email list: > http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |
Dave's suggestions are good ones, but having used a K3 for over 6,000 Qs in
ARRL Phone from P49Y, I can say that they only go so far. You will still get splatter from close stations. The K3 is excellent at not creating digital artifacts due to nearby signals, but unfortunately a lot of the splatter you hear from nearby stations in a phone contest really is in your radio passband, and can't be eliminated by any setting of the controls on a K3 or any other radio. Note, it's also possible to run the DSP at a width as narrow a 1.6 kHz or so in extreme circumstances. Also consider backing off the RF gain at times.

Everyone's ears are different, but I used a DSP passband of 1.1 KHz for most of the 2,200 QSOs I made in the 2009 CQ WPX SSB contest (roofing filter was 8-pole 1.5 KHz). I don't remember how far I had to shift the center frequency, but I think it was down to about 0.85 or 0.90 KHz. It definitely helped, but if the splatter is inside your passband (and unfortunately much of it is) nothing will make a significant difference other than maybe taking the time to tell the guy above or below you that he has a dirty signal (which I did twice) and hope that he backs off the gain or compression (which happened once). 73, Dave AB7E Andrew Faber wrote: > Dave's suggestions are good ones, but having used a K3 for over 6,000 Qs in > ARRL Phone from P49Y, I can say that they only go so far.
