Only thing I will say is that finally the NR is working as it should be after installing this new beta version 3.27 The autonotch is super fast,I tuned a 40db over S9 broadcast station on 40M and could hear a station with S7/S8 at just 2Khz away,even getting closer at 1.5 Khz still could hear the weaker one,that notch works excellent now. NR on CW is outstanding,I was able to pull stations of about 449 signals from the band noise and make them sound crystal clear like a 599 station,impressive performance on CW SSB,the NR even not been so effective as on CW it did work great as well,using F1-2 as settings I can pull weak stations and they will sound very clean with just lightly hollowness,audio is droped little bid only. In general I will give the new 3.27 in a scale from 0 to 10 a perfect 9.5 Good job again Elecraft,obviously you guys are not sleeping as been stated.

The NR seems to be really great in CW (but I liked it a lot in 3.25 as well). It seems to fade into the new settings a bit quicker and not need to be turned off and back on again. Although I find myself being impatient and still doing that at times. I did however go up and try it out on some SSB stuff and it seems to really round out and muffle some of the SSB stuff. I found the signals easier to copy with the NR off than on. However the NR in CW is quite impressive at pulling out some of the weak ones. Its not doing such a good job that I'd not be able to make copy with out it but for me who is a bit green on copying its nice to be able to take many signals and make them sound near perfect. One detriment is that when setting the radio to PB CTRL = 0.1 before it seemed like there was a lot more low frequency response and that the bottom two bands in the EQ finally did something for a change. Is there something that one can do to get that audio back? Testing the auto notch in a labratory type environment I inject an S9 signal and then notch it I get 43dB of attenuation. Inject a 1uV signal and I get 10dB of attenuation. Both make the signal generator sound as if its been turned off. ~Brett On Tue, Aug 25, 2009 at 10:52 AM, Eric Swartz - WA6HHQ, Elecraft<[email protected]> wrote: > Hi Roy, > > As of today, we have made the following enhancements to all K3s leaving > the factory: > > K3 VFO TUNING NOISE REDUCTION (requires f/w 3.25 or later) > K3 AUTOMATIC FRONT END PROTECTION (1 wire mod) > K3 IF OUTPUT BUFFER GAIN MOD (For the P3, LP-PAN etc) (1 resistor value > change) > > Based on feedback form those that have tried the preliminary release of > these changes, we are comfortable with adding them as standard K3 features. > > Please note that the last item, the IF Output Buffer Gain mMod, is > slightly different than the similar N8LP mod some have been performing > on their K3s independently.
