I enabled some of the debug options just to check if the unit initializes.
All seems ok. 
I did some tests on I2C with the i2cscanner and this is what I found

I2Scanner now gives:
Scanning...
I2C device found at address 0x50  !
I2C device found at address 0x57  !
I2C device found at address 0x68  !
I2C device found at address 0x76  !
done

At this point I Think it is an issue on the trasmitter board.
Tomorrow I Will go on the roof and i will verify.  I will keep you informed.
