Modifying QRP circuits to operate on another band Sometimes you see a transmitter or receiver circuit you'd like to build but it's on the wrong band. This series of videos discusses how you might modify it to suit what you want. As you'll see sometimes is a few simple component value changes whereas in other cases a redesign might be needed.             Finally, this is another trick to allow a tuned circuit to be switched for two bands with the one inductor.   Disclosure: I receive a small commission from items purchased through links on this site.
