Devices that have no oscillators generally have no significant signatures either. TRF radios lack oscillators, hence have no significant EMI/RFI signature. The only TRF radio I ever owned certainly had an oscillator. Matter of fact, it had two, one in the mixer stage and one BFO. Except that by definition, a TRF cannot have a mixer stage, it has no IF stages. that why it is called a TRF. I'll take your word for it, but when I learned the term it only seemed to mean a radio with a tuned RF stage, implying nothing more about the radio. Kinda had the sense of "air-conditioned car". -- So those 380 tons of missing explosives were moved by Saddam before all those expert inspectors noticed, eh? No wonder twelve years of inspections found NOTHING. |
