AVT967 A

Amateur constructions of low-power transceiving devices are very popular among radio amateurs. Working with a small power on a hand-made, simple device is experiencing its renaissance. QRP mini-transceivers are very willingly picked up (also by expert amateur radio) outside their permanent place of residence, on holidays, and on holidays.
The presented kit is quite unusual. First of all, it is characterized by an extremely simple construction (as for the transceiver) with small dimensions and satisfactory parameters. It is not insignificant to use SMD components and use cheap and easy to obtain components.

The device is especially recommended for radio amateurs and amateur radio players (especially starting to learn about this hobby)
