Here is the story. One of our suppliers discontinued the IR detector that we were using, and told us this one was a drop in replacement. Well we can tell you for a fact is not. This ones frequency detection is too tight to hear the RC5 36 kHZ signal that we are using in the blinkie.
It works fine as a 38KHz detector.
