Title: "What is all this neutralization stuff anyhow" + Hazeltine TRF Post by: WD5JKO on October 16, 2010, 09:37:06 PM While reading the latest from Bob Pease in Electronic Design magazine concerning "What is all this neutralization stuff anyhow" a fellow named David Sherman chimed in with a comment concerning professor Hazeltine and his "FADA Neutrodyne" radio receiver. The link is below, and the comment is at the end. A pretty good description of professor Hazeltine's work in the 1920's with TRF receivers. http://electronicdesign.com/article/pease-porridge/what_s_all_this_neutralization_stuff_anyhow_.aspx As always Bob Pease is at the top of his game.
