It can support wireless in a couple roundabout ways.
The first is that if you have an external module, like an ERLS module in the back bay, then you can use the internal module to connect to another radio. That doesn’t work for me though because I only have the internal module.

The other way is that you can apparently use a receiver hooked up to the TX16s, and bind the other radio to that. I’ve heard of the receiver being connected via the trainer jack and I’ve also heard about it being connected via the serial ports on the bottom. I’ve been trying to get that to work but haven’t yet. I know that it takes an inverted sbus signal, so I bought an sbus inverter, and I think I have all the settings set up correctly, but I haven’t gotten it to work yet. Has anybody else tried this? I really like this approach because the TX16s provides the power to the receiver so you don’t have to have an extra battery for that. It’s an elegant approach if only I could make it work.
