Improved 7 MHz QRP CW Rig
This QRP CW transmitter's output is 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.
The variable capacitors, coil cores and 100Ω potentiometer are adjusted for maximum clean output.
