The answer to this question is based on the assumption that the radio object has already been created and is functional.

The solution involves the connection of several objects. The first of which is the Signal Function object found on the Controls list under the Math Function submenu. Connect the radio or receiver object to the Signal connection point in this object. Use the +/- keys to toggle through the function field (in blue) until SigNoise appears. The object will now report the received signal to noise ratio of the radio or receiver.

The next step is to send the information to the host. On the Controls list select Outputs and choose either Output Float or Output Integer, depending on the data type you wish to send to the host. Connect the Signal Function object created above into the Output field. Set the data size and number type to match the format desired by the host. Set the data packet, TX1, and desired offset.

The signal to noise ratio from the Signal Function object will now be inserted into the UDP packet sent to the host. The user must not neglect to set the appropriate network parameters on the Host Network menu to enable the transmission of the packet to the host but that is beyond the scope of this question.
