Do you have a range of freqs in mind. It seams to me that if you did not filter out the freq you wanted then you would record all the freqs. Im not sure if that would do you any good because you may want to record a garage remote and at the same time your recording every frequency being transmited through the air.

What are you needs. Are you trying to sit across the street and record the frew of your neighbor who is using his alarm remote to his car to open the car doors or are you going to be 1 inch from the remote and have the recorder set up on a bench.

sound like a cool project at the least. i would love to build it myself. you could have some fun with that.

Project Idea

Hi, I'm really interested in this topic. just wondering, is there any further development on this? I've seen "pirate" garage door opener that can "clone" themselves to other openers from a distance [about 10~15 ft], not only on the old openers, but also on the ones with rolling code. Also, it will catch the frequency and send it back in the same freq. any further idea on this could be achieved?
