PROVIEW1989 Posted April 1, 2007 Report Share Posted April 1, 2007 i have two crystals of the same frequency and i was wondering if i could make them communicate, i mean i need a schematic of a receiver and a transmitter with crystals.is it possible?because i ve searched in google but i couldnt find such a think Quote Link to comment Share on other sites More sharing options...
PROVIEW1989 Posted April 3, 2007 Author Report Share Posted April 3, 2007 Ok but it seems too complicated i need something more simple Quote Link to comment Share on other sites More sharing options...
audioguru Posted April 3, 2007 Report Share Posted April 3, 2007 A radio and a radio transmitter are complicated if you want them to work well.Copy the cheap circuits inside radio controlled toys if you want simple circuits that do not work well.

PROVIEW1989 Posted April 3, 2007 Author Report Share Posted April 3, 2007 c mon i just want to make an experimental communication device with two crystals covering a range of 100km.I m kidding the range i want is 1m no interference is caused by other devices.Do i have to build this staff for an experiment i want to make?i m not a ham thats why i need something simple Quote Link to comment Share on other sites More sharing options...
audioguru Posted April 3, 2007 Report Share Posted April 3, 2007 Even the transmitter and receiver circuits in a cheap $10.00 radio controlled micro car are fairly complicated. Their range is about only 4m. Quote Link to comment Share on other sites More sharing options...
