KSJO DEMONSTRATION SYSTEM
GEO-TARGETED FM/HD BROADCAST TECHNICAL REPORT
https://ecfsapi.fcc.gov/file/10918302769909/KSJO%20Technical%20Report.pdf

This report delivers a summary of key technical measurements and 
associated analysis information on the performance of the geo-targeted 
broadcast demonstration system deployed in collaboration with the KSJO 
commercial FM radio station. Additional technical information necessary to 
understand the context for this demonstration system's performance is also 
provided.

According to the lawyer's cover letter

"Operation of the EAS geo-targeting override. The research confirms that 
geo-targeted broadcasting will not affect the performance of the EAS 
system. Roberson tested this issue through simultaneous reception of 
identical EAS tones at two locations, using separate measurement systems 
in two separate vehicles."
