Elecraft KX3 firmware v1.93

MCU 1.93 / DSP 1.28

• KXPA100 POWER SETTING IMPROVEMENT: The KX3s PWR control can now be adjusted across the 10-watt/11-watt boundary in either direction during transmit (including TUNE mode) without causing a large spike in KXPA100 power output. Also, during TUNE, the “TX” knob function is now always assigned to power output r​ather than keyer speed or mic gain.
• AGC-OFF AF LIMITER NOW WORKING: Some operators prefer to turn off AGC and control gain manually using the KX3s RF GAIN control. However, if an extremely strong signal is present with AGC off, audio output can be uncomfortably loud. The KX3 provides an AF limiter for the AGC-off case. Use the AF LIM menu entry to adjust the threshold at which limiting takes place.

For application programmers:

• "PO" (POWER OUTPUT READ) COMMAND NOW USABLE IN QRO MODE (KXPA100 ENABLED): As with th​e KX3s bar graph, the “PO” command returns an estimate of KXPA100 power output based on KX3 drive level. You can use the KXPA100s “^PF” command to read the amps power output more accurately.
• "OM" COMMAND NOW SHOWS KXAT100 AND KX3-2M OPTIONS: These are represented by the letters T and X respectively in the “OM” response. Refer to the K3/KX3 Programmers Reference.
• ATU.X MD MENU ENTRY (KXAT100 MODE) NOW ACCESSIBLE: When the PA MODE menu entry is set to ON, the ATU MD menu entry changes to ATU.X MD to show the mode of the KXAT100 external ATU. The “MP” command can now be used to read (but not set) the KXAT100s mode in this case. (To change the mode, use the KXPA100s ^MP command.)
