How to extend tuning range with an FM RF alignment - Tube Radio Restoration Back to Basics part 13

Electronics Old and New by M Caldeira

description

Like the AM RF alignment, the FM is quite similar to do. However, I wanted to extend the tuning range beyond the 100MHz that the radios was designed for, as there is a station at 101.6MHz that I normally listen to. In some radios this can be done, and in this video we'll see if and how to achieve this. Enjoy the video.
