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.

Final Assembly and Packaging Your easy receiver kit is now completed. Packaging is left up to the builder. However, for testing, you will find included in the package, an audio connector, 9V battery connector and a BNC along with hookup wire. For initial testing, you can just temporarily connect short wires to the board pads and use alligator leads for connection of antenna and audio out. - Page 8 Connections to Board EZRX 20170527...

Page 9: Setup And Testing
Setup and Testing The Easy Rx has a tuning range of approximately 50-75kHz. This will cover the low end of 40M for example where most of the CW activity is found including QRP frequencies such as 7.030 and 7.040. First verify that when you power up the Easy Rx, and connect an antenna or section of wire, you should hear static and maybe some signals in the headphones. -

Troubleshooting The easy RX is designed to be a simple kit to build and to use. However, occasionally, problems may happen. In our experience, these are often soldering issues (shorts or cold solder joints) or component misplacement Here are a few things to check if the kit does not function as it should. 1. - Page 11 Schematic EZRX 20170527...
