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.

Than you Simon. I really want to get into this one as well. I want to somehow turn my nephew from the phone games to radio games ( ha ). I am sure you now the struggle with the little ones these days. Maybe next month I will have a little time and do this, I had one more request. 73 YO6DXE.
