P3 Firmware Revisions

MCU 1.29 /  May 30, 2014

Latest Regular Production Release

Requires K3 firmware version 4.25 or later.

This release will automatically be recognized by P3 Utility.

  • Added noise blanker feature. New menu entries: NB En and NB Level.

  • Compiler optimization results in a faster update rate.

  • SCALE is now stored by band.

  • Fixed an obscure bug that occasionally caused the P3 preamp to turn off when using CW QSK on the K3 with external keying.

  • Fixed bug: Occasionally RS-232 "get" (query) responses from the K3 would be interlaced with responses from the P3.

  • Added error trap to prevent illegal SPAN condition.

  • Corrected 1-pixel error in tic mark positions on the 6 meter band.

  • Improved operation of the QSY feature. For example, the VFO B cursor now moves automatically when the K3 VFOs are linked.

  • The SVGA reference level is now correct when the P3 amplifier turns on or off.

  • Fixed a bug that caused the FN1 label to disappear when changing to tracking mode.

  • The transmit cursor in Data A mode now defaults to receiver bandwidth.

    Note that units with the optional SVGA module require SVGA firmware version 1.16 or later.


 MCU 1.20 / September 14, 2012

Prior Production Release

  • Supports SVGA data mode, including new SVGA menu entries:  "SVGA data" on/off, "SVGA fntD" (data display font), "SVGA WinR" (receive window size), and "SVGA WinT" (transmit window size).

  • Allows upgrading SVGA firmware with SVGA data mode enabled.

  • The center frequency and span are saved in EEPROM when in "0 Hz" mode.

  • Eliminates possible invalid values for SVGA data font and window size when upgrading firmware.


 MCU 1.16 /  April 27, 2012

Prior Production Release

  • Faster P3 Utility response when no SVGA board is installed.

  • Added the menu selection, "MENU : SVGA menu : SVGA FW" to display the revision numbers of SVGA firmware and FPGA images.

  • Disabling the SVGA now blanks the external display.

  • The external display waterfall color bias is initialized properly at power-up.

  • The AVERAGE and MKRA/B parameter adjustment text on the external display is removed when the adjustment is exited on the P3.

  • The "VFB" RS-232 command now works with the SVGA display.

  • MKR A and MKR B adjustment text on the external display is still on after changing SVGA resolution and after the un-QSY function.

  • The waterfall height adjustment on the external display is terminated when pressing a toggle key on the P3.

  • The display frequency is correct when K3 RIT is on after switching from tracking to fixed-tune mode.

  • Fixed an intermittent bug in the "#QSY" RS-232 command.

  • VFO B cursor displays correctly when VFO B is on a different band.

  • The auto-baud of the K3 RS-232 port works again.  (It broke in version 1.06.)


MCU 1.13 /  March 22, 2012

Prior Production Release

  • Removed 57,600 and 115,200 baud from the RS-232 menu.

  • Added "SVGA font" menu selection to change font size on external display.
    (Requires upcoming new release of P3SVGA firmware)

  • Added "SVGA bias" menu selection to adjust waterfall color bias on external display.
    (Requires upcoming new release of P3SVGA firmware)

  • Monochrome waterfall option now works on external SVGA display also.
    (Requires upcoming new release of P3SVGA firmware)

  • Waterfall averaging on external SVGA display is correct after a power cycle.

  • Span for fixed-tune mode is now set properly upon parameter initialization.

  • Fixed parameter initialization bug that could cause P3 to lock up after band change or parameter initialization.


    There is a known issue in this release with Averaging Control adjustment and the SVGA board: 
    When exiting Averaging Control on the P3, the encoder must be used instead of a short tap of the Display/Average key, otherwise the adjustment text will remain on the external display. 


 

MCU 1.12 /  March 14, 2012

Prior Production Release

  • Fixed bug that sometimes caused high noise levels on the external display upon span changes in tracking mode.

  • Fixed bug that caused reference level to fail to be recalled from flash memory when changing bands in fixed-tune mode.

  • Changed VFO A cursor color to green.

  • Cursor off-screen arrows are enabled when the inside edge of the cursor disappears.

  • Re-tuning in fixed-tune mode when VFO A is tuned off-screen is now based on the center of the passband, rather than the carrier frequency

  • Changed format of MKR A and MKR B frequency readout to match main display. 

  • MKR A zero and MKR B zero now automatically enable the respective marker.

  • Tap-to-QSY works correctly on microwave transverter bands.
