Vastly improved design is more powerful than our 3V MTX room bug and slightly more refined than our MMTX 9V room bug. This circuit uses 2-transistors with the tank oscillator coil built onto the PCB for extra stability in operation. There is a choice of two output powers offering a choice of greater range or greater stability.
You can experiment with different aerial set-ups for greater range and alternative inputs (details provided).
