SRa v2.1

  • User interface now restores channel 2 settings when leaving ratio diversity mode.
  • Fixed transmitter battery metering so the icon will appear empty at the correct voltage when lithium batteries are used.
  • Enhanced squelch system to ignore supersonic emissions from transmitters (especially from analog transmitters using the SRA's analog compatibility modes).
  • Fixed problem wherein an audio level setting of "+1" could result in an incorrect audio level after a power cycle.
  • Improved dynamic tracking accuracy in compatibility mode 6.

Note: If upgrading from v1.4 or earlier, set new FINETUNE menu parameters to 0 for equivalent performance, or follow new calibration procedure for a possible slight improvement in squelching opertion under weak signal conditions.


SRa v1.5

Added factory fine tuning parameters to streamline the factory RF alignment procedure.  If an upgrade is taken to this version, an additional calibration step must be performed to ensure that the new parameters are set correctly.  Also, the LCD now displays a countdown while powering off.

SRa v1.4

Improved diversity and noise squelch systems for substantially quieter operation under moderate to weak RF conditions.

SRa v1.3

FIXES

  • Fixed problem wherein user group V could not always hold 16 channels.
  • Applied bug fixes and sonic refinements to mode 3.
  • Balanced CPU load to speed factory diagnostics.
  • Inverted audio polarity.
  • Turned off unneeded signals to reduce RF radiation from DSP.

SRa v1.2

Fixed minor display glitch, added automatic birdie warning, improved response to sharp acoustic transients.
