Pacific Antenna 40M Easy Receiver Kit

Description

The Easy Receiver kit from Pacific Antenna is designed to be easy to build and use.  It covers approximately 75kHz 
of the 40M band and can be assembled in about 1-2 hours.  

It has no toroids to wind and only one adjustment (trimcap) to set the frequency.   

It is a direct conversion design employing a front end bandpass filter, NE602 mixer and LM386 audio amplifier.

Our Easy Receiver is designed to work with our Easy Transmitter, Easy Audio Filter, Easy Tuner and Easy Keyer  and 

Easy TR switch to make a complete QRP station.   

These boards are designed so that, if desired, they can be stacked together to produce a compact assembly.
