[Elecraft] New K3 f/w: MCU 1.48, DSP 1.45 and new Downloader version available
Except for those CW ops who leave their K3 on a spot frequency and use the NR to reduce the background hiss level a bit... Again a feature has been removed on an upgrade (NR no longer works for bandwidths below 500 Hz). I've gone back to MCU ver 1.45 and DSP 1.43. Dave, G4AON K3/100 #80 === NR continues to evolve.

This is not in general a good idea, because each release contains bug fixes as well as new features. The 500 Hz restriction is temporary. -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco K3 no. 7 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] New K3 f/w: MCU 1.48, DSP 1.45 and new Downloader version available
We've just released new K3 firmware: MCU V1.48 and DSP V1.45 * Power output via -external- CW keying no longer jumps up slightly above requested level. * Noise reduction much improved, including insertion loss compensation. * S-meter accuracy improved. * LINE IN state preserved on power-off. We have also released a new K3 software download utility, V 12.09, that has improved error recovery and several other new features. See http://www.elecraft.com/K3/k3_software.htm for more info. 73, Eric WA6HHQ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

* Noise reduction much improved, including insertion loss compensation. Can you offer a little more information about the NR? In this version of NR, the set levels are in four groups of four, whereas previous versions have been 0 to 39 or 0 to 3. Additionally, I noticed that the NR does not appear to work below BW of 500Hz. Is that true or am I just not noticing the effect? NR continues to evolve. The latest version, as you noted, has four settings for each of four groups. The lowest numbered setting in each group is the gentlest, while the highest setting in each group offers more noise reduction but slower response. If find for SSB use that I usually use the 2nd setting [ NR F1-2 or NR F2-2 ]. The F4 group can have a sort of hollow sound for voice under some conditions, but is excellent for narrow modes like CW. Below a width of about 500 Hz, NR is disabled in the current release. We have more code we are testing now that allows its use down to the nominal 50 Hz wide filters in CW mode. If testing goes well, it will be released in due time. Even more exciting, we are also testing... oops, I'd better not say! 73, Lyle kK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Hm, I forgot to download that, but it appeared that the previous loader worked fine. When you have the loader check for new firmware, I guess it doesn't check for new versions of itself. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
