  • Ah, yes. 27 Mhz AM will give you whatever sound the TV is currently playing *thru the radio* if you tune the radio there and put it close enough. After string a wire antenna down the hallway, I was able to tell what show my parents were watching on the TV in the living room just by tuning to 27 Mhz and listening to the radio only.

    It seems 27 Mhz is an oscillator crystal frequency used in newer TV's, especially flat panel.

  • I understand it takes 20A + to transmit? I am very limited in DC power availability. Is there any way to reduce my tx and rx power consumption on the 450s? Thank you for revealing your findings in this vid experiment.

  • I love my Kenwood TS-450SAT very nice radios.
