I'm trying to display the flightlevel on my 16 char LCD-Display for my XPDR. Unforunately the indication is allways "FL---".

Any chance to solve it?

If you select the type 4 (TT31 transponder) it works as real TT31, showing "FL---"  in the On and SBY modes,  see the demo slideshow here: http://simvim.com/svc_custom_radio.html

When mode is in ALT or GND you will see the FL025  etc.

For types 1,3 the "FL" is not showing, only the digits are.

What is the transponder type you have selected in the configurator?
TT31 In the map

You should change the transponder mode by "hardware" switch (rotary), not on-screen knob.

It works like a real TT31, accordingly with it's  docs.

ist working, i feel so dumb haha, sorry for that
Sorry for answering late. It is working fine now. Thank you very much.
