K3 beta-test firmware revision 3.97 (with DSP rev. 2.58) is now available. This revision has several significant improvements; see release notes below. (Note that "QRQ" mode -- enhanced high-speed CW -- will be in the next release.)

Odd-numbered DSP NB levels (t1-1, t1-3, t1-5, etc.) apply the new algorithm, while even-numbered levels use the original. To avoid unwanted interaction between the NB and on-air signals, always use the lowest effective setting. * CW KEYING ARTIFACT WITH AFX/DELAY ELIMINATED: The “DELAY” settings of AFX previously created a small audio artifact when listening to CW keying in the presence of background noise or signals. * AGC-OFF S-METER IMPROVEMENT: Turning AGC off no longer results in a drop in the S-meter reading. This was most noticeable in the presence of strong band noise. * K144XV S-METER NOW ACCURATE: The S-meter reading is now adjusted to account for RX gain when the K144XV is in use. * TX NOISE GATE IMPROVED: The voice transmit noise gate now uses a downward expander rather than simple gating. See TX GATE menu entry for further details. * MANUAL NOTCH: Pitch now defaults to 1000 rather than 2000 Hz. This starting point is a better compromise between CW and SSB. * ESSB ON/OFF COMMAND: The new “ES” control command can be used to turn ESSB on/off via a switch macro or from a software application. The K3 must also be in LSB or USB mode before ESSB ON takes effect. (See K3 Programmer’s Reference.) * BN REMOTE CONTROL COMMAND (BAND CHANGE): Previously this command was “GET only”, returning the present band number (00-24). It can now be used as a SET command to switch to the desired band. For example, BN00; switches to the last-used frequency on 160 m. Note: VFO B will also be restored to its last frequency used on the new band, except in the case where CONFIG:VFO IND is set to YES. ______________________________________________________________ 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
