K3 beta-test firmware revision 3.41 (with DSP rev. 2.37) is now available. See release notes below.
More refinements are in the works. But alas, it was time to "shoot the engineers" and get some interim feedback on the many new features in this revision. -------------- IMPORTANT NOTE -------------- The latest version of K3 Utility (1.2.9.30) must be used if you plan to do receiver RF gain calibration. You can find K3 Utility on our K3 software page, along with the K3 beta-test firmware: http://www.elecraft.com/K3/k3_software.htm Please send problem reports to [email protected]. 73, Wayne N6KR * * * MCU 3.41 / DSP 2.37, 10-02-2009 * IMPROVED RX LOW-FREQUENCY RESPONSE in AM/SSB/CW MODES: Most noticeable with hi-fidelity headphones or large speakers. NORMalizing the DSP passband still sets the cutoff to about 100 Hz, but DSP controls can be adjusted to provide a lower response. RX EQ can enhance bass further. * NO RX EQ OR TX EQ IN DATA MODES: That is, the response is flat (rolling off below 200 Hz). The RX EQ and TX EQ menu entries now affect only the other modes. * "LIVE" MEMORY RECALL (M>V): If you tap M>V, then start rotating VFO A to select a memory, the K3 will now switch to the band/mode of each memory. Exit memory recall by tapping M>V a second time. * VFO COARSE STEP ROUNDING: Tap '1' in the VFO CRS menu entry to select RND=NO or YES. If YES, the VFO frequency will be rounded off during COARSE tuning. This menu entry also sets the per-mode COARSE step size. Note: The RIT/XIT control moves the VFO in coarse steps if RIT and XIT are not in use (use CONFIG:VFO OFS to turn this on/off). * CWT (TUNING AID) NOW INDEPENDENT FOR CW & DATA. * RF GAIN CALIBRATION PROCEDURE UPDATED: You’ll need the latest revision of K3 Utility and a 50-microvolt signal source (e.g., an XG2). * SUB RX NOISE BLANKER NOW FULLY INDEPENDENT OF MAIN: This includes the on/off state and NB LEVEL settings. Note: Set CONFIG:NB SAVE to YES to preserve your per-band NB on/off settings. * DSP INTERNAL STATUS MONITORING: In the TECH MD menu entry, tapping 1 (main) or 2 (sub) displays DSP status information. If it is “FFFF”, no error has been detected. Tapping CLR resets the data to “FFFF”. * CHANNEL HOPPING IN FM MODE LOADS REPEATER SETTINGS: Repeater offsets and PL tones are now loaded during scanning/hopping. * PL TONE DEVIATION ADJUSTABLE: Tapping '1' in CONFIG:FM DEV allows setting PL tone deviation (300-600 Hz in 30-Hz steps; default, 360 Hz). * EU REPEATER 1750 HZ PL TONE BURST: If a 1750 Hz PL TONE is selected, a 500 ms tone burst will be sent on each PTT activation. * EXTENDED 6-METER TUNING RANGE: The VFO can now be tuned down to 44 MHz to monitor signals that may be correlated with 6-meter band openings. Loss increases rapidly below 49 MHz (-34 dB at 45 MHz), so a preamp (e.g., the Elecraft PR6) may be needed to obtain a useful NF. ______________________________________________________________ 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
