So looking around, I don't see anyone really describing what protocol they use, so it's hard to figure out which boxes work. Seems like people are really only interested in wifi.

So can you be more descriptive in your message?

I know that the navworx ADS600-B box works, but it's 978mhz out only.
The freelight box is $4000 and is also 978mzh only http://www.freeflightsystems.com/pro...gr-transmitter
I can't find any GDL-90 serial output on anything from Stratus, which box are you talking about?
Ping, is that from uavionix? The ping station or ping usb? The usb one looks like it emulates a serial port over usb, will that work on the AF4500? I can't find anywhere where it says the serial protocol is GDL-90.

What I really would like is a 1090mhz transceiver, with GDL-90 output and wifi, and I don't see such a thing.

Thanks for the help,
