The Grape III: Pondering new varietals for the RF vineyard

Grape I is a straightforward low-IF receiver based on the venerable NE612 Gilbert cell chip. Grape II is a much more involved 3-frequency, computer-controlled receiver. Grape III will be--what?  The CWRU Grape team will discuss possibilities for the next generation of inexpensive, high-accuracy receivers that will provide HamSCI, NIST, Canadian Research Council, and others a continuous data stream.  Anticipation of signal processing, ease of manufacture, and ease of deployment will be among the top issues.  Several receiver architectures and data collection modalities will be considered along with candidate signal analysis approaches and related chipsets.  Notes will be taken from audience questions and suggestions, and new design teams will be solicited for the project.
