PCBWay Project - Pititico 2 CW Transceiver.jpg

Description

Pititico 2, QRP CW Transceiver

A simple QRP CW transceiver with one transistor and an audio amplifier, based on the Pititico CW Transceiver designed by PY2OHH. This is the 40m band version and it has about 700mW output power. It's a modified version for easier adjustment of the TX frequency and the offset frequency. It also has an improved low pass filter for better harmonics suppression and a modified circuit to remove most AM broadcast band interferences. In the videos are the older versions. In the blog article you will find more detailed info.
