Re: [Elecraft] So, anyone going to get more CW filtering?
Last week I sold my 500 Hz filter, and ordered a 250 from Elecraft. On Friday night, the new filter hadn't arrived yet, so I operated in the CW DX Contest with only the 2.7K filter. It worked great! I couldn't see any difference between the 2.7K and the old 500. The skirts of the DSP (set at 300 BW) dominate over the filter skirts, and I never had one case of desensing or overload. On Saturday afternoon, the mailman delivered the new 250, and I installed it immediately and operated the rest of the contest with it. Once again, I couldn't see any difference. The radio sounded exactly like it did with the 2.7K and the 500. If you frequently feel the need to crank your DSP width way down below 300 Hz, you may benefit from the 200 filter, but I don't do that and don't plan to buy the narrow filter.

Re: [Elecraft] So, anyone going to get more CW filtering?
I echo Dave's remarks, though I have the 8-pole 400Hz filter. Being in VT made me the focus of several spot pileups, but I experienced none of the desense issues that someone reported on the reflector. There were numerous wide stations, which caused me to tailor the RX EQ settings in an effort to further reduce the audibility of their key clicks. All in all I can say that the K3 (built in January) performed flawlessly. The only item on my wish list is an outboard tuning device to sit on the desk to the left of the keyboard (like my former Omni VII). 48 hours is a long time to reach up to the rig (on a shelf at eye level above the laptop screen) and the keyboard up/down arrow facility isn't flexible enough (station spacing on the band is fairly even, so you want to zip up the the next station and then slowly tune it in). I can see that I'm going to wear out the paint above the bezel where the fingers of my right hand rest while my thumb rotates the dial.

Re: [Elecraft] So, anyone going to get more CW filtering?
Interesting. I had the opposite experience. I was on 40 meters yesterday afternoon for about 30 minutes. Signals were all pretty strong as Europe is just across the pond from my QTH. I did a lot of listening, comparing 1.1 KHz with 1.0 KHz and 550 Hz with 500 Hz. The difference of course, is that my 1 KHz and 500 Hz filters kick in. What I heard was a noticeable reduction in thumps, pops and AGC desensing as I stepped across the filter engagement boundary. There were a number of situations when I was at 550 Hz and could hear the other guy's signal being pumped up and down as my AGC was affected by someone 400 Hz away. I step down to 500 Hz, and the other guy's signal suddenly becomes smooth and consistent - no more AGC pumping. - Keith N1AS - - K3 711 - -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Dave Hachadorian Sent: Monday, February 23, 2009 9:52 AM To: Elecraft reflector Subject: Re: [Elecraft] So, anyone going to get more CW filtering?

Re: [Elecraft] So, anyone going to get more CW filtering?
Ah, yes, Dave, that would make a difference. Enough of a difference that you and I are *almost* running different rigs :-) With AGC off, and AF gain up, I assume you ride the RF gain in response to RX signal strength. Cut RF gain for a strong one and boost it a bit for a weak signal, right? If you have RF gain boosted a bit for a weak signal, how do you control the strong ones that suddenly appear in the passband? - Keith N1AS - - K3 711 - -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Dave Hachadorian Sent: Monday, February 23, 2009 11:30 AM To: Elecraft reflector Subject: Re: [Elecraft] So, anyone going to get more CW filtering?

Re: [Elecraft] So, anyone going to get more CW filtering?
The problem with any of the shuttle knobs or keyboards with integral shuttle control is the need for software support. Most of these devices operate by emulating a mouse wheel (the scroll wheel) and it is not easy to use the external knob to tune while reading e-mail or surfing the web. It would be handy if logging/control programs (e.g., CI-V Commander from DXLab Suite) could capture a specific device like the Griffin Power Mate or Contour Shuttle Express/Shuttle Pro for exclusive use and operate in the background. The shuttle knobs are not so much a problem with contest software like N1MM Logger since that's not likely to be used in the background ... but the same considerations would apply if they were. 73, ...
