problem with sending data using RF module

[Archangel]

Hello rano_zen06,
Looking at your code . . . not however, trying it out . . . Is this all of it? I do not see anything to cause the transmitter to send data from the keypad, unless I have become legally blind . . . or stupid . . . that is why I asked is this all of it. As I said . . I see empty variables in the serout routine.

 SEROUT TransmitterPIN,T2400,[Synk,Synk,9,Counter]

I would try adding a string to the serout routine for test purposes only, something like

SEROUT TransmitterPIN,T2400,$FE,1,["1 2 3 "]
