K3 beta-test firmware revision 3.77 (with DSP rev. 2.53) is now available.
This revision corrects a possible frequency offset between the main and sub receivers in diversity mode. With earlier firmware, a small offset can sometimes be introduced if you adjust the VFO A frequency or RIT offset while transmitting. See release notes below for details on other changes. Please send any questions to k3supp...@elecraft.com. For instructions on how to load beta firmware, see: http://www.elecraft.com/K3/k3_software.htm 73, Wayne N6KR * * * MCU 3.77 / DSP 2.53, 2-27-2010 * DIVERSITY MODE MAIN/SUB RECEIVER OFFSET FIXED: In some cases a small frequency offset between the main and sub receiver could be introduced due to transmitting while moving VFO A or the RIT offset. * SUB RECEIVER BAND-PASS FILTER SWITCHING FIXED: If the main and sub receivers were configured for independent band selection (CONFIG:VFO IND = YES), switching the main receiver to any of 17-10 m may have caused an incorrect band-pass filter to be selected for the sub receiver. * SYNTHESIZER TABLES UPDATED: Reduces the DDS tuning range slightly to minimize group delay through the DDS crystal filter. (These tables are located in the “HFPF0108” file, part of the firmware download package. It will be loaded automatically if you check "send all files to K3".) * AFX “BIN” MODE FIX: Stability improvement for the “BIN” audio effect (selected by MAIN:AFX). Previously, a loud audio artifact could occur under certain receive-signal circumstances. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
