Thanks Werk. I put a fair bit of effort into creating a timber and stainless steel case for the RX unit in order to make sure the " Boss of the house" didn't object to the appearance and ask me to put it in the Shed  . 

I will have to go and check the TX unit - can't remember what I did there.

You my not believe, but I added the "big clock" as a screen saver option (instead of just turning off the backlight) thinking on the " Boss of the house". A clock is something which normally doesn't bother the "Boss of the House"  

Perhaps you haven't installed it, or haven't enabled it on the TX software

Code:

#define USE_TMP36       1          // 0= Not Instaled, 1= Intalled
