Schematic Diagram Uhf Tv Transmitter

If you are going with a dc power supply then it must be well regulated and free of noise.

Schematic diagram uhf tv transmitter. Either a 12v dc power supply or a battery can be used for the purpose using a battery will surely reduce noise and improve the performance. Frequency is determined by a resonator fl1. The transmitter schematic can e modified to produce am modulation by eliminating d1 d2 r2 r3 and r6 and short circuinting a and b points. In principle the transmitter should work up to 500mhz or more using the bf959 bipolar transistor.

The values given in the schematic diagram set the transmitter to about 600 700 mhz that is in the range of 37. Can be used the following types.
