Oscillator design 0-12 MHz
Hello
If anyone can recommend me a good book from which i will learn to construct oscillator that for example covers range 0-12 MHz. Thanks in advance! Tom |

Thanks in advance! Tom 12 MHz is easy. 0 MHz is really difficult. 73 de Leigh W3NLB ------------------------------------------------ Nah for 0 MHz -- have a switch labeled 0 MHz -- fed by a battery. Its the 0.00000000000000000000000000000001 Hertz that will be a problem All in good fun. Seriously you need to decide on accuracy and stability first which will dictate whether you will be building an analog, or synthesized unit. For an analog homebrew project -- see URL: http://www.vintage-radio.com/project...enerator.shtml Covers 150kHz to 12 MHz. For the lower frequencies -- get a hold of some of the later solid state Heathkit Audio generator manuals. Or from scratch -- consider the following books: http://www.sss-mag.com/cosc.html#books |

Thanks in advance! Tom 12 MHz is easy. 0 MHz is really difficult. 73 de Leigh W3NLB The workaround is to have a variable oscillator beating against a fixed oscillator. So you have your variable oscillator going from 30 to 42MHz (I just picked those out of my hat), a fixed oscillator running at 30 MHz, and a mixer fed with both oscillators. The output of the mixer will be 0 to 12MHz (plus some other things). Michael VE2BVW |
