 An Arduino based sweeper for ham radio homebrewing.
 This is based on an Arduino and AD8307 based W7ZOI power meter and either an Si570 or an Si5351.
 
-This needs the Si570 library from https://github.com/sarfata/radiono/tree/master/radiono
-The circuit details are avaiable on http://hfsignals.blogspot.in
+This fork allows usage of the more modern Si5351 library that can be installed directly from the Arduino IDE. 
+Also, modifications have been made to use a rotary encoder for tuning, rather than a potentiometer.
