I have an inexpensive walkie talkie (under $50/pair). It receives
FRB in 400 MHz and weather stations in 160 MHz region. It is both
sensitive and selective. I can not find any schematics also I do not
see any IF teransformers. Is it a superhet and if not how do they
achieve such great performance in a TRF design?
