VR/E01 (Venue/Europe) Firmware History

VR/E01 v5.5 - 13 February 2013

Added a new analog compatibility mode: "Mode 7". Also enhanced squelch system to ignore supersonic emissions from transmitters (especially the native "Mode 7" analog transmitter).

VR/E01 v5.4 - 18 October 2012

Adjusted the pilot tone capture and release thresholds for more consistent talk-back functionality.

VR/E01 v5.3 - 01 August 2012

Modified PLL logic for improved module detection with newer Rev. B modules.

VR/E01 v5.2 - 29 June 2012

Modified GUI interface to expose Talk Back activity and control (for use with VRpanel version 3.1 or later). TX battery status has been adjusted to increase accuracy with lithium style batteries. Start-up routine has been modified to prevent the need for "re-detection" after power up with newer style receiver modules (Rev. B).

VR/E01 v5.1 - 22 February 2012

Fixed a bug that prevented Ratio Diversity from being selected.

VR/E01 v5.0 - 25 January 2012

Modified PLL compatibility for use with new PLL IC. Added Talk Back functionality for use with new HH transmitter. Fixed a minor timing bug that resulted in occasional jumpy rotary control. Version 5.0 (or later) is necessary for newer modules built with the PLL IC, and is fully backward compatible with older style modules.

VR/E01 v1.6 - 19 January 2011

Fixed a bug in version 1.5 that limited the opportunity for detection of modules with laggy (but not broken) PLL's. On occasion, instead of being detected, they would show as an unknown block, depicted by a "?" on the main screen.

VR/E01 v1.5 - 13 December 2010

Added logic to allow the future use of different PLL IC's in modules. Added compatibility for a new eeprom IC. The logic works with both new and old IC's alike. Lastly, the module detection algorithm was modified to acknowledge a module, even if the detection signature was unknown. The user is then able to manually assign a block to that module.

VR/E01 v1.4 - 22 January 2010

Added 110, 300, 'mode 3', and 'mode 6' series compatibility modes. Improved diversity and noise squelch systems for substantially quieter operation under moderate to weak RF conditions.

VR/E01 v1.3 - 03 September 2009

Fixed a register initialization error that could theoretically cause the DSP to not boot during system start up. No evidence has surfaced that this bug has ever manifest.

VR/E01 v1.2 - 18 August 2009


  • Scaling for european units only applied to the low band signal in relevant modes (hybrid & exp200), increasing apparent RF sensitivity.
  • Bug fixes and further sonic refinement to mode 3.
  • Fixed noise floor in combined diversity modes.
  • Limited occurrence of "Check Frequency" message.
  • Added compatibility for new analog headphones switch.

(This firmware works with both old and new hardware versions, and knows which switch is installed by the unit's serial number.)

VR/E01 v1.1 - 04 June 2009

Module detection algorithm modified to avoid slight tick in audio. Channel indicator in custom mode now uses hexadecimal rather than a decimal channel number. Applied bug fixes and sonic refinement to mode 3.

VR/E01 v1.0 - 27 May 2009

First production release.
