need automated frequency finder circuit

Post by two55309 » Wed Sep 03, 2003 10:28 am

I need a schematic for an automated frquency finder circuit. I live in the city which has lots of interfence. I have designed all my projects to work off different fm and uhf frequencies and would like to consolidated them all into one remote control. Thanks to anyone who can help.

You need to be more specific.

I have a total of 8 projects to control. As of right now, i use 7 differnet remotes. They all use the same basic functions so it would be nice to have only one remote control. I looking to build a frequency finder circuit that could switch between each one. Preferably have it automated so that it would look for the next highest frequency and cycle through them. And have each project send out a signal. <p>I have tried to build this, but to know availe. I could not figure out how to make the frequenc finder circuit. I use frequencys from 11Mhz to 95Mhz. And then from 500Mhz to 3.6Mhz. (I liketo experment with different frequencies. I also have a FCC expermentail license, so i don't worry to much.) <p>Thanks

you built these and don't know the frequencies? Does not make sense.

I know the frequencies. But I want to be able to expand for future use. That's why i want it to cycle through them. I could build all 8 into one remote, but i don't to keep adding a circuit for every project.
