I am attempting to reverse engineer the signal from a 300 MHz garage signal as a learning experience rather than an exercise in efficiency. My intent is to purchase a 300 MHz broadcaster IC and connect it with a microcontroller so that I can have a neat gadget that controls a few gates. My quest has led me to software defined radio. I purchased the recommended dongle, the R820T, and fired it up. After much tweaking I was able to isolate the frequency.(much happy)
I found the signal, then recorded and extracted the .wav. Then I zoomed into the desired signal from the .wav file in Audacity.
I've heard the 10 digit key (each one in one of two positions) should be readily apparent from the signal.
Can anyone help me understand how I can get the key from this signal or any other tips on deciphering?
Here is the current remote config for this signal:
Here is the Multicode 3089 remote that i received the signal from: http://multicoderemotesonline.com/Multi-Code_Remote_3089-11.html
