The duty cycle is calculated as below. There are 1000 bit intervals in a .1 second period. A 40% duty cycle (500 high bits) was assumed to insure worst case scenario as the testing was done before the actual duty cycle was calculated. Sounds to me that the part recommended by RFM to help the receiver sensitivity may be a viable solution. I look forward to seeing if there is any improvement. Here are some snap shots from my data scope (real world). Looking at the short message lengths being used...73 bytes. Almost 30% of the .1 second interval we are quiet (nice for an emission average).
