I’ve been playing with Airwire a bit in my spare time and I’ve come across a very cheap way to build an Airwire compatible receiver. It will drive any large scale DCC decoder using battery power. No programming, just hookup a few modules that you can get from Ebay and Amazon and it works. All together it costs about $30 (without the decoder obviously) It does require a bit of soldering and a voltmeter but it’s pretty easy. If you are interested, I’ve put together a set of instructions with links where you can get the modules. You can find it at the below link:
