Tracking chips in HD radios

An HD radio has no transmit capabilities, and you know it. How do you know - Very simple... it doesn't transmit. """""""""""""""""""""""""""""""""""""""""""""""""" """""""""""""""""""""""""""" Every superhetrodyne transmits a signal via its oscillator. Example 1. In WWII Nazi submarines used TRF receivers as the oscillator in a superhet put out enough signal that air and naval sub chasers could home in on the signal and deep-six them. Example 2 In 1985, my auto Radar detector, the latest in Stealth technology, was detected by a police cruiser using even later detector technology. "Oh sure," chuckled the cop as he wrote out a ticket," I heard you right across the valley." Example 3. My old diode detector radar detector was invisible to the police detectors. Therefore, when buying a new iboc radio, tell the clerk that you insist on a TRF model that will ensure your privacy. Wearing your tinfoil hat might help get his attention. I am sure that small-signal reception techniques have improved since 1944. |
