KX3 Production Firmware Revision
MCU 2.38 / DSP 1.37, 1-3-2016
See KX3 Firmware Release Notes for a complete revision history.
This release can be automatically downloaded by KX3 Utility

  • POWER OUT NOW 15 WATTS MAX, 80-20 M: On 80-20 meters, the PWR control can now be set as high as 15 W (max is still 12 W on other bands). Supply voltage must be over 12.8 V on key-down as indicated by the KX3’s voltage display (tap DISP, rotate VFO B). Note: The KX3 will automatically reduce power as required if current, SWR, or temperature is excessive, or if supply voltage is too low. If a band other than 80-20 m is selected, power output will be cut back to 12 W max. It must then be manually set above 12 W after switching to 80-20 m.

  • PSK63 MODE ADDED: Tap DATA, rotate VFO B until PSK D is displayed, then use VFO A to select 31 or 63 baud. The default is PSK31.

  • 4-METER POWER OUTPUT IMPROVED: Changed IF band-pass filter configuration to increase drive level on 4 meters. This should improve 4-meter power output in cases where it was marginal due to filter rolloff.
  • 10 W OUTPUT DOWN TO 10-V SUPPLY: The KX3 can now put out up to 10 W from a supply voltage as low as 10 V on key-down, assuming that other parameters remain within range (current, temperature, and SWR). This will allow the use of up to 10 W for much longer when running from an 11-V battery, such as a 3-cell Li-ion pack. While we still recommend the use of 11 V or higher when using 10 watts output, this change will allow you to get a few extra dB in the field when you really need it. NOTE: Transmit IMD performance is better at higher voltages. When running from a 10-11 V battery, only use max power (10 W) when absolutely necessary. Home stations should use a 13-14 V power supply when running full power.
  • 2 METER/4 METER TX CURRENT LIMIT INCREASED: Transmit current can now be somewhat higher when using the internal 2-m or 4-m module. Previously, some units were not able to attain full power output.
  • EXPERIMENTAL CW QSK MODE: Tapping ‘3’ (APF) in the CW WGHT menu entry selects either OLD QSK (original) or NEW QSK (which purges the DSP’s audio pipeline on every key-down). NEW QSK reduces audio artifacts heard in the receiver during CW keying on a noisy band, at the expense of a slightly longer receive-recovery time. (We hope to speed up RX recovery in a future release.) To verify the benefit of NEW QSK: First select a CW RX filter bandwidth of 400-1000 Hz, then transmit 20 WPM dits (at 0.0 watts) on top of an S5 or stronger carrier, or in the presence of S7 or stronger atmospheric noise. While transmitting, you can be in the CW WGHT menu entry, alternating between OLD and NEW QSK by tapping ‘3’ (APF).
  • 60-M U.S. BAND LIMITS CORRECTED: CW/DATA, TUNE, and ATU TUNE are now usable on all 5 channels. Previously, BND END was displayed in some cases. Note: This also applies to other countries where the U.S. band limits are used.
  • RX EQ NO LONGER APPLIED IN DATA MODES: Previously, the RX EQ settings for voice modes were being applied to data modes.
  • KX3 CHANNEL HOPPING UPDATES PX3 DISPLAY PER-MODE: When channel hopping is used (by tuning the VFO or scanning), the PX3 display is now updated based on the mode of each “channel” (frequency memory) in the hop range. This is especially useful on 60 m, which includes both CW/DATA and SSB allocations. See page 17 of the owner’s manual for scanning/channel-hopping setup instructions.

电离层:早就升级过了! (2016-03-15 10:57) 

上次固件低电压10W输出有没有实测下射频功率啊?我升了还没测试实际功率。
