[Elecraft] Regarding the K3 and high QRN levels

[The Smiths]

Not to say that either of you are using your rigs incorrectly, or that you're opinion is wrong, I loved my TS520 to death,  but I've found that people who keep their RF gain cranked all the way up as high as it can go, then rely on the DSP NR to fix the noise for them are almost always disappointed or unimpressed with DSP noise filtering.

The only time that I've ever heard the Reverb affect is when I have too much DSP trying to repair a noise issue that could have been taken care of by simply reducing the RF gain down to the noise floor level, or just above it, then introducing as little DSP as necessary to combat the noise.

That along with other great features such as the Filters, NB, and Notch filter you can really get a nice clean signal out of the K3.  I know this because I have a constant S3 noise level on 30 meters without the Pre-amp on, and S5 with it.  On 40 I'll usually peak up to about S8 or S9 noise.. Still, with the above things I've mentioned I've been able to work weak signals with low noise interruption.. All without the mentioned Reverb affect.

 

Being that you own the Orion 1 you should know this better than anyone.  With the Orion you MUST keep that RF gain down (usually around 70 - 75) otherwise that DSP will completely fail.. I know the one I had did, every time.
