The filters are working great! After receiving my beta rig I did alot of listening during the first contest I could find. Hearing weak CW sigs with nearby sigs at +30 and +40 2 kHz away was no problem...even with closer spacing there was no problem.
I presently have 400 Hz, 1.0 kHz, 2.8 kHz and a 6 kHz. I will also have a 200 Hz filter installed which will be great for CW and digital modes. What I really like is being able to only turn on the filters for a particular mode that I want to use. Its easy to setup....so I activate the 1 kHz and 400 Hz filters for CW and DATA modes and the 2.8 and 6 kHz for SSB. When adjusting the WIDTH control, the active roofing filters will will automaticlly be selected as soon as you cross its threshsold. So if I am on CW and listening with a wide BW...say 800 Hz, the 1kHz will be in line. Rotating the knob down to 400 Hz or below will switch to the 400 Hz filter. No need to do anything else. But..if you want, you CAN manually select another filter and the DSP BW will normalize to match that BW. Another neat filtering option is the I/II toggle. I keep a filter profile set up as wide in the I bank and narrow in the II bank. So instead of having to make manual adjustments, I can just use that HOLD feature to toggle between the two setting. For casual operating.....you "can" suffice with the supplied 2.7 kHz filter and use the DSP for the final BW. But you are not going to get the most out of the K3's capabilities by doing so. Look...you're getting a top of the line receiever here. And if you are getting one, I suspect at SOME time you will dabble in at least a contest or two or some DXing....even with casual operating you are at times going to come up against some strong nearby signals. You WILL want the tools available to deal with them effectively. If you work CW....I really recommend at least the 400 or 500 Hz filter options. If you are doing allot of contesting...get one even narrower...and it will suit your digital mode needs as well. ------------------------- 73, Greg - AB7R Whidbey Island WA NA-065 On Thu Jul 19 7:57 , "Franki ON5ZO" sent: >> If I was into DX or contests on CW, I would likely get >> a narrow CW filter, but I am not so I did not. >> I suspect the K3 will work better than any other radio >> with just the 2.7kc filter. > >I was just about to post a question regarding filters yesterday.
