Many people who are interested in electronics, have old digital scale taken from an old car receiver. That tool can easily get damaged and make it difficult to retune a processed receiver. Its another disadvantages are cables and not very attractive look.
In this project, you can got an idea how to improve such a device.
Assumptions:
- small size
- battery powered (or with possibility of an additional power supply – in this case it is a 9V battery, but it can be replaced with an accumulator as well)
Dipswitch is a switch of all possible functions of the device.
The design of the board was inspired by kit AVT 2666.
The meter is perfect for beginners – it is small, simple and do not require programming anything. As an instrument for retuning the receivers it works and facilitates repair.
