Elecraft KX3 firmware v2.76

MCU 2.76 / DSP 1.50

• FINER STEPS FOR AF GAIN AND MONITOR LEVEL: Both the monitor level (MON) and AF gain control ​now provide somewhat smaller increments.
• AF GAIN LEVEL RESTORED: An earlier firmware release unintentionally reduced the KX3s maximum AF gain.
• ATU DATA SETS FOR USE AT DIFFERENT LOCATIONS: The KX3 will now store two full sets of per-band data for the internal ATU (KXAT3). Use the ATU DATA menu entry to select which set to use. Typically SET 1 is used at a home location, and SET 2 for field operation. Note: This has no effect on KXAT100 ATU data, which is stored separately for each of the KXPA100 amplifiers antenna jacks.
• ATU LC NETWORK VALUE DISPLAY: In either the ATU.DATA or ATU MD menu entry, tapping the "ATU" switch shows the present values of L (inductance), C (capacitance) and N (L-network configuration). This applies only to the internal ATU (KXAT3). The displayed data format is LxxCxxNy. <xx> is a 2-digit hexadecimal value that, when converted to binary, shows which ATU L or C relays are engaged. <y> shows which side of the L-network the capacitance is on: Nt = TX side, and NA = ante​nna side.
• ATU CLEAR AFFECTS ONLY CURRENT DATA SET: Within the ATU DATA or ATU MD menu entries, CLR (hold of the OFS/B knob) now clears KXAT3 ATU data only for the presently selected data set (SET 1 or SET 2) on the present band. As before, CLR is recommended when using the internal ATU with a new antenna. Once the data is cleared, very few ATU tune operations will usually be needed to cover an entire band. Note: If a KXPA100 amplifier is connected, the CLR operation applies to the KXAT100 ATUs per-band/per-antenna data, not to the data for the internal KXAT3 ATU.
