Gary,

It's not hard to install .. basically you just plug the TX into a computer with the USB cable, then it looks like an external disk .. just like when you update the transmitter firmware if you've done that.

The Jeti studio app is very nice .. you might consider downloading it from Jeti .. it is very helpful for hiding some of the complexity.

You copy the lua file (e.g. speedannouncer.lua) from your computer into the Apps directory on the transmitter which is mounted to your PC as a disk. Then you can install it from the applications menu on the TX. When I post the code, I'll put up a simple process. Probably Esprit has some videos on it.
