Before revision: The "Wadley loop" was mostly used in more expensive stationary radio receivers, but the "Wadley loop" was also used in a portable radio receiver (Barlow-Wadley XCR-30 Mark II).radiomuseum.org: Barlow-Wadley XCR-30 Mark IImanualslib.com: Barlow-Wadley XCR-30 Mark II Overview In a traditional superheterodyne radio receiver, most oscillator drift and instability occur in the first frequency converter stage because it is tunable and operating at a high frequency.
