KXPA100 PER-BAND POWER CALIBRATION IMPROVED
KXPA100 DRIVE CALIBRATION DATA SHOWN BY TX GAIN MENU ENTRY: If the PA MODE menu entry is set to ON or Pout CAL, and PWR is set above 10 W, the TX GAIN menu entry will show drive power in watts needed to hit 75 W at the KXPA100 amp . A letter 'A' or 'T' prefixes the drive power value shown, depending on whether the source of the calibrated drive value is the Amp or the Transceiver.
MCU 1.76 / DSP 1.27, 11-20-2013
Initial KX3 f/w release with KXPA100 support
MENU:PA MODE NOW HAS POWER-OUT CAL (P out CAL) SETTING: This enables 75-W power calibration in TUNE mode. When PWR is adjusted, and “P out CAL” mode is in effect, setting power to 75 watts shows “CAL 75W” on VFO B.
KXPA100 DRIVE POWER CAL DATA UTILIZED: If the KXPA100’s per-band 75-W drive power has been saved at the factory, the KX3 will use it. If not, the KX3's own per-band amplifier drive data is used (if available). This data is created by setting PA MODE to Pout CAL (see above), then doing a TUNE on each band at 75 W.
IMPROVED POWER CONTROL. As the KX3’s PWR control is adjusted, the KXPA100’s output now more closely approximates the requested value.
KX3-2M SUPPORT (instructions TBD).
DTMF TONE SUPPORT ADDED IN FM MODE: To generate DTMF tones: (1) Hold PTT; (2) tap FREQ ENT switch to enable DTMF keypad; (3) tap desired switches [0-9, * (ATU TUNE), # (MSG), A (MODE), B (A/B), C (DATA), D (A>B)]. Release PTT or tap FREQ ENT to disable DTMF keypad. Switches can be held indefinitely to generate longer-duration tones.
FM RX & TX IMPROVED: Reduced FM distortion on receive. TX deviation max now 6.0; default 5.0 (U.S. standard).
