Seems like ADC overload. Assuming N6BV is line of sight, a quick calculation would be:

1500 watts = 62 dBm
10 dBi of TX antenna gain
87 dB of path loss at 14 MHz
10 dBi of RX antenna gain

62 + 10 - 87 + 10 = -5 dBm

There's also the loss due to a small hill in N6BV's direction and the fact that I had my beam pointed directly away from him.

Several were on air this past weekend for ARRL CW, including I'm told a very high scoring entry. I'll let you guess which one.

I'm sure I can guess who. At that level, however, it's the Indian, not the arrow, that counts. All the top contesters have gear good enough to win.

Absolutely! And not even using top of the line radios. A famous world-class contester uses a pair of TS-590's. He's always at or near the top of the heap in every major contest.

I had a chance to compare the NR on my 6400 against my 590S and I can report that it is better than the 590.  With the 590 I really could not go much past 3 - 4 with out reducing the RF gain to stop the waterfall sound.   The 6400 has significantly less waterfall artifacts than the 590.   I can leave it on with the slider at about 10% and it pretty much removes most of the noise. 

The only thing I have noticed is that I loose some high end frequency response.  I would still recommend using adjusting the gain 1st and then NR 2nd,  but I can see where it will certainly help.

 I suspect the better results are more of a SmartSDR 2.1.x upgrade rather than a hardware upgrade.

My friend has a 7300 and a 6400 now and I am waiting for him to do some comparisons.  So far he is very impressed with the 6400.   

I have not had any RFI to test the NB out on yet.   I hope I never have too.

You are not kidding.  My 7600 looks better than that.  I have to wonder if the guy has it improperly set up because if that's what the display looks like, NO THANKS.

The rig already has that old Ten Tec toaster oven stamped metal look about it, it should at least have a decent display.

Check the release notes - there are a whole raft of waterfall color/fill/fill-density/FPS/rate options.

I have mine fairly monotone in comparison.

Steve, I'm quite sure that video is not faithfully displaying ANY of the waterfall color options.  Have you watched it?

Please tell me the video camera was the blame for that display in that video and not the display itself.
It looks terrible. !!

Quite of lot of the mentioned artifacts are reflections of the clothing.

Not only may he have had camera issues, but the lighting and staging introduced more issues.

Filming these types of screens must be challenging. 

Go look at one in person, or check out some other videos. 

What we also need to remember is if there was something that really wasn't right that corrections could be released in the next SmartSDR update.

Sometimes it is hard to get one's "here and now" fixation out of one's mind, given the redefinition possibilities for the architecture.

Don't they charge a couple of hundred bucks for software updates Steve?  Sometimes when someone pays that much money for a product they expect it to work at least as well as less expensive radios right off the bat without having to wait for software updates to be available for purchase.
