One of the first things that will happen upon the release of the K3, is someone will connect a D104 to it. ;-)
This can be the worst thing for a radio, or a very good thing depending on how it is connected. If one of the beta's has connected a preamplified D104 to the K3 I'd like to know what is the specific wiring and that would be a good thing for the K3 operational FAQ. As for CW receive audio, I agree that DSP radios often sound "strange" as compared to analog radios for a few reasons. The IC756Pro has a lower frequency "rumble" than you would hear with respect to band noise on an analog radio. The 500hz DSP filter has a very "hard" skirt noise as compared to a 500hz crystal filter it's fatiguing. K3's "context filtering" mode should be very good for this. Then there are AGC differences, the 756pro is never quiet when the AF gain is turned up. It's a radio that's better (on CW) to be played at lower AF levels through walkman style headphones. The DSP only Argo V I has none of these characteristics, and although it's prone to strong adjacent signal AGC pumping, is a much kinder implementation of DSP in my experience. The adjustable AGC on the K3 will be the biggest problem solver in my estimation, I can't wait to hear it. Lastly DSP radios sometimes will add artifacts to what you would hear on an analog setup, unusual sounds of short duration in the receive audio (see Rob Sherwood's Dayton presentation on his website) and Wayne has gone the long mile to ensure that this in no way will be a shortcoming in the K3. Good things coming - good things coming - mo mojo. ! ------------------------------------- Hi Ron: >I read in the previous postings that the CW sounded better on the K2 >than the K3.

In general, I've received just the very OPPOSITE reports. Most say that the K3 has some of the very BEST sounding keying that they've heard! And this from a number of folks whose opinions I value quite highly. The audio compression of the K3 really adds a lot of punch to the signal without introducing a large amount of distortion or artifacts, and the bandwidth does not increase significantly, as it does in some other rigs. 73, Tom N0SS _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
