K3 beta-test firmware revision 3.30 (with DSP rev. 2.26) is now
available. See release notes below. Please send problem reports to [hidden email]. Beta firmware load instructions can be found at http://www.elecraft.com/K3/k3_software.htm 73, Wayne N6KR * * * MCU 3.30 / DSP 2.26, 9-1-2009 * FIXED NOISE BLANKER ON/OFF SWITCHING IN BSET MODE: You can now independently turn the noise blanker (NB) on/off for the sub receiver in all cases. Previously, the NB switch was locked out in some cases in BSET mode. * DVR TRANSMIT WITH MANUAL PTT: Normally, playing a DVR TX message (M1-M4) automatically asserts PTT and goes into transmit mode. Now, you can manually assert PTT prior to playing DVR messages, if necessary. (This might be required to meet external equipment switching requirements at some stations.) To do this: in the CONFIG:KDVR3 menu entry, tap ‘1’ until you see “USE PTT”. (This setting is ignored in VOX mode.) * ELIMINATED AUDIO NOISE BURST WITH NR + AUTONOTCH: Very rarely, the combination of NR and autonotch, in the presence of a strong signal, could result in a loud audio artifact. * MORE NR (NOISE REDUCTION) SETTINGS: There are now 32 NR settings. F1-x to F4-x originally appeared in firmware revision 3.27, and are recommended for most applications. F5-x to F8-x are the same as F1-x to F4-x from firmware revision 3.25. They provide a varying mix between processed (“wet”) and unprocessed (“dry”) audio. When x is 1, the mix is mostly "dry"; when x is 4, it's 100% "wet". A small letter “m” (e.g. "NR m F5-1") reminds you that "mixed" settings are in use. Note 1: When you’re experimenting with different NR ADJ settings, allow 1 to 3 seconds for the DSP to fully adapt to present signal conditions. Note 2: F5-x and higher NR settings may alter the amplitude of single-tone (CW) signals somewhat, depending on the pitch. Voice signals are less affected. --- http://www.elecraft.com ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Bingo! SubRX NB working at last.

Excellent work -- best of both worlds. Exactly what I was hoping for!
Now if only PB CTRL SHIFT=.01 had the same 0.40-2.60 FC range as SHIFT=.05 ... (nudge) ;-) 73, Paul WW2PT
