I would agree with Wayne. My prime use of my K3/10 is not HF, but with transverters on VHF and up, typically weak-signal CW. I ordered my K3/10 with the 2.8 and 400-Hz 8-pole filters as a good overall approach. I added 13-KHz for VHF-FM and occasional BC/SW AM using the gen coverage option board.
I believe this coupled with the variable bw DSP filters will work well for me. My occasional listening on 20m and 40m CW indicates how nice the 400-Hz filter works, essentially picking out only one CW signal in a crowed band. Adding a little NR makes it very comfortable copy. BTW the NR works nice to quiet down SSB, but then I am wandering off your subject, Chris. I have a 30-year old VM-35 Astron that has run all my 100w radios thru the years. I did blow up the regulator chip trying to use it as a battery charger. that ought to cover all the questions! ------------------------------ Message: 15 Date: Thu, 15 Jul 2010 16:17:26 -0700 From: Wayne Burdick <[email protected]> Subject: Re: [Elecraft] K3 on Order To: Chris Hembree <[email protected]> Cc: [email protected] Message-ID: <[email protected]> Content-Type: text/plain; charset=US-ASCII; format=flowed; delsp=yes Hi Chris, Hope you enjoy your K3. One thought: If you operate any CW or narrowband data at all, I think you'll want at least one narrow filter (500 or 400 Hz). It'll make a huge difference in crowded band conditions. If you're strictly into voice modes, you can do without. 73, Wayne N6KR 73, Ed - KL7UW, WD2XSH/45 ====================================== BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 144-QRT*, 432-100w, 1296-QRT*, 3400-fall 2010 DUBUS Magazine USA Rep [email protected] ====================================== *temp ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
