  • Third Overtone
  • Receive frequency + 10.8 MHz = crystal frequency
  • HC25/u holder

Bearcat High-band

  • Third Overtone
  • Receive frequency - 10.8 MHz / 3 = crystal frequency
  • HC25/u holder

Bearcat UHF-band

  • Third Overtone
  • Channel frequency - 10.8 MHz / 9 = crystal frequency
  • HC25/u holder
