End of the Line for Collins Mechanical Filters
The ARRL Letter reports that Rockwell Collins has decided to stop manufacturing its venerable mechanical filters after more than 60 years. According to an announcement on the company's website, demand for the mechanical filters has dropped dramatically as radio designers have switched over to digital signal processing techniques.
The announcement did not include a specific date after which the filters would no longer be made.
