RC

A regenerative radio reciever built by Westinghouse in the early 1920's. The RC consisted of the RA (reciever) and DA (amplifier) units placed in one enclosure.

The Westinghouse RC was one of the first radios produced for home use.

radio

There are many different types of radio receiving circuits:
-Crystal (see above)
-Regenerative
-Tuned Radio Frequency (TRF)
-Superheterodyne

Modern radios are superheterodyne. The superheterodyne circuit replaced the TRF and regenerative circuits by the 1930's, and crystal sets were nearly dead until solid state radio emerged.

The superheterodyne circuit uses a local oscillator.

TRF

Tuned Radio Frequency (see radio)

I have a TRF radio from 1925. It's difficult to use compared to what we use now.
