In your transmit code add delay(1000); into loop() to slow things down. An Arduino works very much faster than any serial communication.
In your Original Post you said you are using SoftwareSerial but neither of your programs uses it. Trying to use HardwareSErial for debugging and for transmitting is just going to cause confusion.
I don't have time now to study the Wireless device manual - I will bookmark this for later.
