KX3 beta firmware rev 1.48 (with DSP rev 1.20) is now available. See detailed information below.
You'll need the KX3 Utility application to download and install firmware. For full instructions on loading beta releases, refer to our KX3 software page: http://www.elecraft.com/KX3/KX3_software.htm DETAILS: The KX3's noise blanking level can now be set using the knob above the NB switch (AF/RF-SQL). When NB is turned on (by HOLDing the NB switch), the present setting (1-15) will be displayed on VFO B for about 3 seconds. To select a new setting, rotate the knob before the display times out. The display will then persist until you tap any switch. A subsequent hold of NB will turn the NB off. The NB setting is stored per-band, as is the NB's on/off state. Important notes: - The noise blanker is intended to reduce the amplitude of repetitive pulse noise with a fast rise time. It will not suppress atmospheric noise. For that, you may want to try NR (noise reduction). - Noise blankers will cause a certain amount of intermod or shaping of signals when set too aggressively. We minimized this with our new DSP algorithms, but you'll still want to use the lowest effective setting. "NB 1" will do the least blanking and create essentially no artifacts. Settings up through "NB 8" or so will still minimize artifacts. If the noise is really strong, you can go all the way up to 15. These higher settings are great for digging out weak signals, but can modify the sound of strong signals somewhat and cause some pumping on a busy band. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
