Elecraft K3S firmware v3.97

MCU 3.97 / DSP 2.58

• TX INH​IBIT IMPROVEMENT: If TX INH is active (see CONFIG: TX INH), voice monitor and CW/DATA tones are disabled, giving the operator audible feedback about inhibited status to supplement the flashing ÒTXÓ icon.
• DSP NOISE BLANKER IMPROVED: A new algorithm has been added that makes the DSP NB more effective on some types of noise. 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 ÒDELAYÓ 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 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 ÒESÓ 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 Programmers Reference.)
• BN REMOTE CONTROL COMMAND (BAND CHANGE):

Previously this command was ÒGET onlyÓ, 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.
