There seem to be two different definitions of "TRF" floating around. Definition #1: A TRF radio has one or more tuned RF amplifier stages before the mixer. Definition #2: A TRF radio has no mixer. There are one or more tuned RF amplifier stages, then a detector, then one or more audio amplifier stages. Which makes a TRF radio sort of like a radio with a volume control, in that neither volume control nor TRF says much about any other aspect of the radio's design. ![]() -- 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. |
