Hello,

I don't fully understand what you are trying to do, or what your schematic is looking like but I would try the following:

1. You said it only works on Transmitter 1.. That is case statement 1.

For this, I would drop the case statement and us "IF" "Then" statements... see if that makes a difference.

2. You have extremley long pauses after each recieve... the first 2 have 2 second pauses, the last one has 1 second pause.... Is this too long of a pause??? Is it necessary?

3. Baudrate... 9000 Try something like 300 first.
