Dave, Haven't used a Timewave 599zx with a K3, and only for a half hour or so with my KX3.
However, I did use the 599zx with an older non-DSP radio for over a year and it made a tremendous difference in CW (don't operate phone much, so no comment). But my urban QTH is -very- noisy. After I got the KX3 I tried it - and it made a slight difference, maybe. But not enough to bother, so I put it in a box and there it has stayed. Been planning to sell it one of these days, but, you know... Note that on the KX3, using CW, I have the bandwidth down to 400Hz or less, as well as using the NB, Notch, and other tricks. The old radio had a narrow crystal filter, but the ringing was so bad I could barely stand listening to it. So it was rarely used. In that situation the Timewave Audio DSP was very effective. As to Jim K9YC's comment, I won't argue because I've never used it with a K3. I would just add that when you live in noise hell, "audio distortion" is so far down the problem list as to not be relevant. 73 Chris NW6V > ------------------------------ > > Message: 7 > Date: Thu, 5 Dec 2013 07:35:25 -0500 > From: Dave Wank <dhw...@hotmail.com> > To: "elecraft@mailman.qth.net" <elecraft@mailman.qth.net> > Subject: [Elecraft] K3 and a timewave Dsp 599zx > Message-ID: <col125-w25ac6197d658d8009b06eed0...@phx.gbl> > Content-Type: text/plain; charset="iso-8859-1" > > Hi to all.Just wondered if anyone has used a Dsp 599 zx filter with a K3, and > what were the results.Thanks for any info...73 NK8A...Dave > ______________________________________________________________ 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
