Description

40 Meter Radio Receiver Kit 80-1440

This kit lets you receive amateur radio CW and S S B transmissions in the 40 Meter ham radio band at 7.00Mhz to 7.300Mhz.

This receiver uses the direct conversion method which converts radio frequency signals directly to audio in a single step.

In this circuit that function is primarily accomplished with the SA602 I C.

The IC also contains an oscillator circuit whose operation is controlled in part by varactor diodes and associated tuning components.

Even though this kit is relatively simple and the receiver is easy to operate, it is still a high performance circuit.

This circuit is provided with a fine-tuning commonly referred to as band spread tuning.

This makes it easy to tweak both CW and S S B signals for best reception anywhere across the full 40 Meter band.

Kit output will drive headphones or a small speaker.

The receiver is designed to operate from a 9V dc battery source or better yet 6 AA alkaline batteries in a holder.

Please Note: PC Board not included with this kit.

Kit includes a 6 page instruction booklet with assembly drawing and schematic.

Antenna connector and 8 Ohm speaker not included.

Kit contains over 40 components.

This kit contains small parts and requires assembly.
