Re: [Elecraft] K3 Trade my 1.8k for your 2.1k filter
Swap has been arranged. A few asked why I wanted to switch so here's the simple answer. I operate SSB primarily in contests. In the CQWW SSB I found the 1.8k was a little too narrow when running stations at high rates (>150/hr). In contests stations often call slightly off frequency (+/- 100 Hz) and I found myself needing to widen the passband to ~2.0k for best copy (which kicked in the stock 2.7k). In fact I never used the 1.8k much in the entire contest. When working stations on a single frequency (such as a DX pileup or a net) the 1.8k works fine when you have time to tune carefully. And yes I do know how to adjust HI CUT (and Fc) for best readability at narrow BWs. Hopefully the 2.1k will be a better solution for me in the ARRL SSB DX Contest in March. 73, Bill W4ZV __ 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] Latest Sherwood table
> I wonder how such a high performance filter would work in the K3? Not that its needed in the K3. However in the interest of science, it might be a worthy pursuit. It also might push the K3 well ahead of the FT5000 in ultimate performance. Not very well since it's at 70 MHz. ;-) The Inrad filters are already better than whatever is in the FT5000 since Sherwood measured ultimate rejection in the K3 at 105 dB vs 90 dB for the 5000. 73, Bill W4ZV __ 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
