VU2NAN - NANDU
Simple 7 MHz QRP CW Rig
This is the schematic of my very first solid-state 7 MHz QRP CW transmitter. A heatsink is required for the transistor.

The part count is less than 10. The 1000 pF variable is adjusted for maximum brilliance of the lamp.
DX on this rig was ~1000km (VU2SL in Valsad).
