First check your DHT22 connection.
Then you could try a test sketch. On The RX board the DHT22 data pin is connected to Arduino pin 9.

Thanks for the suggestions. Just tried a sketch I found on the Adafruit site which works for all types of DHT sensors and loaded it into the Weatherduino Nano. Tried the DHT22, no good! Tried a DHT11 which I have and modified the sketch for DHT11 and it reads temperature and humidity without a problem.

The DHT22 is dead! Maybe I let the smoke out but didn't see it.
