Experimental narrowband FM receiver for the 2-meter band 

This project is about MC3362 and ADF4351 based, modularized, narrowband FM receiver. In this design, the receiver splits into three modules as RF preamplifier, MC3362 tuner, and ADF4351 oscillator.
This video shows the assembling, initial adjustment steps, and the testing of the receiver with a local amateur radio broadcast.
