Elecraft KX3 firmware v2.01

MCU 2.01 / DSP 1.29

• SUPPORT FOR KX3-4M MODULE (70 MHZ BAND) ADDED: The 2M MODE menu entry has been renamed as 2M/4M since it now applies to bo​th the KX3-2M and KX3-4M modules. The 4-meter module is set up the same way as the 2-m module, except that XVn RF should be set to 70, and XVn IF should be set to 21. All modes and features are supported on this band. Maximum power output and other specifications are to be determined.
• 2-M FM CURRENT DRAIN REDUCED: The 2M/4M menu entry now has several “sleep” selections: SLEEP .25 (0.25 seconds) through SLEEP 1.0 (1.0 seconds). These specify the sleep time between receive-signal checks when the receiver is squelched. With these settings, average receive-mode current drain is reduced by up to 50%, especially useful when ru​nning from a small battery.
• MORE ACCURATE KXPA100 POWER CONTROL: The KX3s PWR control can be used to set the KXPA100s power output. However, actual output varies somewhat with load impedance, supply voltage, and per-band gain. The operator can now obtain more accurate amplifier output by using the TUNE function immediately after setting PWR or changing bands. Power will be automatically adjusted to the target level within a few seconds, by using wattmeter data read from the amp (via the control cable).
