K3 beta-test firmware revision 2.78 (with DSP rev 1.98) is now available. See release notes below.
Please send any problem reports to k3supp...@elecraft.com. For instructions on how to load beta firmware, please see: http://www.elecraft.com/K3/k3_software.htm We also recommend that you use the latest revision of K3 Utility, which can also be found on this page. 73, Wayne N6KR * * * MCU 2.78 / DSP 1.98, 1-8-2009 * SIGN-ON BANNER SUPPORT (for your callsign, etc.): If you specify a sign-on message (using K3 Utility), it will be displayed when you turn your K3 on. This might include your call sign, serial number, etc. K3 Utililty revision 1.1.12.29 or later is required. Click on the Configuration tab, then click on Edit Sign-On Banner. Up to 22 characters can be entered. If you delete all characters from the message, no banner will be shown. Misc. Changes: * SSB SPLIT TX AUDIO PROBLEM CORRECTED: In certain cases (ESSB, VFO A/B on different modes, or SUB turned on), going into SPLIT mode would result in no SSB transmit audio, or an incorrect transmit audio passband. * VFO COUNTS PER TURN CORRECT AFTER EXIT FROM COARSE TUNING: Previously, if you had CONFIG:VFO CTS set to 400 or 200, selecting COARSE tuning would leave VFO counts/turn at 100 even after switching to another tuning rate. (100 counts per turn is used for coarse tuning due to the large step sizes.) * SUB/MAIN AF BALANCE CONTROL: Main and sub RX audio are now correctly restored when the sub is turned on/off, etc. Previously, either receiver might have remained muted after sub on/off when SUB AF was set up as BALANCE. * DVR WITH COMPUTER CONTROL (HRD, ETC.): Running HRD (and some other PC applications) no longer terminates DVR record/play. Some programs were polling every second or so for the DVR’s firmware revision, which stops the DVR. The K3 MCU now handles this command in all cases without DVR interruption. * AM DSP BANDWIDTH DISPLAY NOW SHOWS *AF* BANDWIDTH, NOT IF. We originally showed the IF bandwidth in AM mode since some operators might be thinking about the underlying AM-mode implementation (i.e., the IF bandwidth has to be twice the AF bandwidth in this mode). But this was causing a lot of confusion, and was inconsistent with the way the DSP bandwidth control works in other modes, where the *AF* bandwidth is displayed. Also, LO and HI CUT show AF cutoff points – not IF – even in AM mode. So we now consistently define the function of all DSP controls as showing AF frequencies/bandwidths. Note: In AM mode, tapping XFIL will still show the *crystal filter* bandwidth, not the DSP BW. So if you select a 6-kHz crystal filter by tapping XFIL, you’ll see “FL2 6.00” displayed (for example). But the DSP width control now be at a starting point of 3.00 kHz. Also see related change to “FW” remote-control command. For software developers: * AM-MODE "FW" COMMAND CHANGE: The filter bandwidth command (“FW”) was reporting the IF bandwidth in AM mode (multiplying by two) which was confusing for users of some PC applications. It now reports the DSP (AF) bandwidth in AM mode. As with the manual WIDTH control, the IF bandwidth is set to approximately twice the AF bandwidth when an “FW” set command is sent. (Note that “K31” mode must be in effect in order to use “FW” to get/set actual bandwidths.) * ENTERING SPLIT CROSS-MODE VIA "FT;": This no longer results in icon flash, so no dummy SWT command is needed to cancel it. (When split is turned on using the K3’s SPLIT switch, the cross-mode warning flash is still present.) --- http://www.elecraft.com _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
