SR v2.2

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

SR v2.1


  • 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.
  • Adjusted squelch system to avoid "ducking" extremely loud, sharp audio transients.
  • Fixed minor display glitch upon leaving menu after browsing past ratio diversity mode without selecting it.
  • Added a periodic warning in the event that channel 1 is very close to 4.5 MHz higher than channel 2 (to avoid degradation of RF performance).
