There are a growing number of
agencies and systems in the area that are
switching to systems that cannot be picked up
with an "off the shelf scanner".
Sometimes its due to privacy/security, otherwise
it's for cost constraints or to meet
narrowbanding guidelines.
Below is a partial list of systems, those marked
"difficult" may be intercepted with
computer software and a modified radio receiver,
provided the system is not additionally
encrypted.
Current laws allow reception of propriety
formats, however if encrypted their successful
interception is considered illegal.
