I am considering these two filters for a K2 that I'm about to buy. I'm mainly a cw guy.
I've had experience with audio filters, but not DSP. Actually now that I think about it, my TS-570DG has an audio DSP filter of sorts. I strongly dislike the audio coming out of it as harsh and grainy. I've listened to the demos for ssb and cw on the Elecraft site for the DSP filter. The noise reduction is dramatic, but the audio sounds, well, digital. If the K2 is as quiet a receiver as I've read, does the DSP trash up the received audio? And how does it do with power line noise? I would be interested in anyone's comments and impressions of these two filters in real world operating situations, even though they are apples and oranges. Is DSP worth three times the money in your opinion, and why? ------------------------------------------- You might gain some experience with the K2 for a while and decide what there is about the rig without either module that you'd like to fix. The DSP has awesome capabilities but, like you, I don't like the sound of digitized audio. The KAF2 was something I had planned on when I built my K2 in 2000, then when I listened to a couple of them I sort of never got around to ordering my own - and haven't missed it. For my ears, the K2's I.F. filters do the whole job just fine. That's the inherent advantage of the K2. We have a lot of options to tailor it to our personal interests and needs. I'm 99.9% CW yet I added the SSB option for the flexibility to work SSB and digital modes whenever I wanted to do so and I've never regretted doing so. If I had been trying to logically deduce what I'd want before using the K2 as a CW op, probably I'd have skipped the SSB module and gone for one of the filters instead. >From the messages I've seen here on the reflector, if you do buy a module you don't want there's usually someone around the reflector who is looking for a pre-built unit so you can recover the bulk of your costs to try it out.
