Improved 7 MHz QRP CW Rig

Here's the circuit diagram of my QRP CW transmitter with an output of the order of 5W.

Fairly comfortable QSOs are possible with the higher power level. The driver and the final transistors require heat sinks. The aluminium enclosure serves as the heat sink for the final.
