KXPA100 Firmware Release Notes

01.39 12-5-2016

Widen timing window to more reliably detect pushbutton switch presses.

01.37 8-9-2016

Enable PX3 image capture through KXPA100. 
Requires updated PX3 Utility and PX3 firmware.
Change PC side RS-232 to 1 stop bit when transferring image.

01.35 12-18-2014

Add manual switch to disable amplifier with ATU available.
MODE button HOLD now toggles power amplifier bypass.
Power ON LED blinks slowly when PA is bypassed.

01.33 6-23-2014

Change frequency counter to require lower power, but more samples if the input power is very low.

01.32 5-18-2014

Increase frequency counter inertia

01.29 4-22-2014

Add instant forward power query for KX3 ALC

01.28 4-8-2014

Correct a configuration save bug introduced in 01.26

01.26 4-2-2014

Correct power input computation

01.25 3-28-2014

Tolerate forward and reflected power overshoot for brief periods to support external antenna tuners.

When attenuator is acquired because of SWR or high reflected power, release attenuator immediately on next key up if SWR has been reduced to under 3:1.

01.23 3-13-2014

Use input power to qualify frequency counter samples

01.22 3-8-2014

Adjust input power threshold test and timing to compensate for end-of-tune overshoot

01.19 3-1-2014

Remove low supply voltage fault log entry when turning amplifier off

01.18 2-27-2014

Add Antenna Enable (one band) command:

•	Get format: ^AEbb; where bb is Band Number, 00-10 for 160-6 meters
•	Set/response format: ^AEbbn; where n is 1, 2, or 3 to enable ANT1 only, ANT2 only, or both antennae.

Add Antenna Enable (all bands) command:

•	Get format: ^AEA;
•	Set/Response format: ^AEAnnnnnnnnnnn; one digit n for each band 160-6 meters, where n is 1, 2, or 3 for ANT1 only, ANT2 only, both antennae.
•	Alternate set format for all bands: ^AEAn; where n is 1, 2, or 3.

See KXPA100 serial command reference.

Supported by KXPA Utility 1.13.3.4 and later.

01.15 2-19-2014

Reduce dissipation faults in band change

Bug fix: amplifier would not key immediately after tune with high drive power

01.12 2-11-2014

Transmit two RS-232 stop bits, which will work with programs that expect 1, 1.5 or 2 stop bits. Now Ham Radio Deluxe version 6.2 connects through KXPA100.

01.11 2-8-2014

Reduce delay forwarding RS-232 data from PC host to transceiver

01.09 1-28-2014

Reduce minimum power required for full search tune and frequency count

01.07 1-10-2014

Remove input power attenuation and fault checks when PA bypassed

01.06 1-10-2014

Adjust band voltage table based on Yaesu FT-817 measurements

Accept higher input power during ATU tuning

01.05 12-31-2013

Fix a command forwarding problem when commands start with a null character (Pignology's PigKnob)

Adjust band voltage table from IC-703 measurements

01.04 12-16-2013

Changes to improve production testing

Use smoothed averages for dissipation and input power fault detection

Do not use attenuator when dissipation threshold reached

01.00 11-18-2013

First production release
