10.58 to 10.74 MHz VFO Oscillator  -  Electronic Circuit design (added 02/05)
2 Stage Chaotic Colpitts Oscillator for the UHF range -  Chaos in the Colpitts oscillator was first reported at the kilohertz frequencies [1]. Later the circuit was investigated in the high frequency (HF: 3 to 30 MHz) range [2,3]. Chaotic oscillations were demonstrated….
4 Transistor Tracking Transmitter -  Schematic and parts list only, no circuit description included…. [Tony van Roon's circuit]
4 Transistor Transmitter -  This circuit provides an FM modulated signal with an output power of around 500mW. The input Mic preamp is built around a couple of 2N3904 transistors, audio gain limited by the 5k preset..... [Design by Paul K Sherby]
Audio/Video Sender -  This circuit provides you with wireless audio and visual transmission to a TV. The TV acts as a receiver, eliminating the need to buy a separate monitor. You can also hook it up to a VCR or CCD Camera, and even set up a remote CCTV security system!....Circuit design (added 02/05)
