Philmore regenerative receiver
WebbThe Philmore probably uses the standard pentode regen design: a series fed tickler coil taken off the plate, with screen voltage regeneration control.

WebbTony Westbrook recently contacted me about a regenerative receiver kit he has designed and produced in the UK. It’s called the KRC-2. Here’s the product description: 1 – 30 MHz with band spread tuning. Regeneration with a difference. The regeneration setting on the KRC-2 is unaffected by the receiver tuning or the antenna coupling. http://www.iw5edi.com/ham-radio/4115/wd5hoh-regenerative-regen-radio-receiver

WebbTuned radio frequency receiver. This 1920s TRF radio manufactured by Signal is constructed on a breadboard. Tuning a TRF receiver, like this 5 tube Neutrodyne set from 1924 with two stages of RF amplification, was a complicated process. The three tuned circuits, controlled by the 3 large knobs, had to be tuned in unison to the new station. WebbW7YRC Yavapai Amateur Radio Club
Webb12 juni 2024 · Simple receivers just had some bandpass filtering in the front end and no preamp. The biggest disadvantage of super-regen receivers is their lack of selectivity and poor adjacent channel rejection. One of the 433MHz receivers used a 418MHz SAW oscillator to down convert to 15Mhz followed by a 15MHz super-regen for AM detection.
