Didn't get a whole lot done on Sunday as I was out flying models and bench running micro diesel engines. Some pics on the RCGroups Model Diesel Engine thread here:

Some videos on Fiery's (a clubmate) Youtube channel here:

Cut and mounted a piece of FR4 fiberglass sheet.
Mounted the Lemonrx DIY transmitter module to the sheet, just behind the meter. Unfortunately, I neglected to take a photo but you can see the double sided tape showing through the FR4 that holds the module in position.
The module LEDs shine through the meter a lot better than I had hoped and are easy to see. Couple of photos below.
Wired up the buzzer and it's transistor. This is mounted with hot glue to the transmitter case, just below the encoder. I like it as, when active, it sounds like a cricket chirping away inside the case.
Testing in the workshop shows everything working as it should.
I will do some range checking next weekend at the club field before comitting the radio to aviation.
Thanks to Phil_G for the code and great documentation that makes this whole process really easy. It's all here:
