I just received an email today from Mark Mahan, Tech Support, Sandel, regarding Skywatch. It reads as follows:
"Dr. Mr. Shirley:
The Sandel SN3308 has no provisions to display any information from the BF Goodrich Skywatch. We have had requests for this feature and are researching the possibility of adding this feature to the SN3308. The WX500 Stormscope can be displayed on the Sandel, GNS430 and ARNAV display in the SR22. Each device displaying Stormscope data will be independent of the others, allowing independent selection of mode and range.
Please contacu us if you have any additional questions.
