Re: [Elecraft] DSP for K2
The MFJ-784B works very well, I much prefer it over my K2's internal DSP. I picked one up used for $100 and think it well worth the cost new. It is fully tuneable and the DSP noise reduction allows you to adjust how 'aggressively' it works in addition to noise level. The auto notch and manual notch work great. It is well worth reading the manual cover to cover to fully utilize its features. MFJ did good with this one.

[Elecraft] DSP for K2
Hello Andy, If you don't need a DSP WITHIN the K2, any other outbroad unit should be good enough. KDSP2 is only at the AF stage and has no filtering in the IF stage.

I have a KAF2 and it is a nice device to have that has little impact on the current drain from the batteries. That is important to me because my K2 is almost always running off it's internal battery. The only DSP unit I have used with a radio is a JPS NIR-10 outboard DSP unit which I used with a Yaesu FT-890. With some noise it did such a good job you had to look at the radio to see if it was still on. With steady tones it worked a treat. CW would turn in to just clicks and all those people tuning up on wouldn't be noticed other than by a slight reduction in the level of the signal you were listening to (due to the IF reacting to the tuner upper). I found it was worth buying the DSP unit. Having the noise reduced (substantially on higher bands), makes ragchew or long periods of listening much more pleasant. During net operations, or while trying to bag that rare (DX) station you need for the log, multi-notch filtering really helps save ones ears from the tuner-uppers. The KDSP2 unit would be handy if you find your operating could benefit from what it can offer for just the cost of a slight increase in current draw. Being built in to the radio, it will always be there if you go portable. An external DSP has the advantage of being usable with other radios but would be complicates things when it comes to having to get power for it during times of portable operation. -- Cheers!

Re: [Elecraft] DSP for K2
Steve I have a K2 also. I have a noise reduction speaker made by BHI out of the UK that is very effective in reducing QRN. You can look up the speaker in W4RT.com.
