I sent them a E-Mail asking if i could bring in a handheld scanner and i got this in reply.
Could you provide me a bit more detail on your request. If your referring
to a standard handheld radio/police scanner bought from radio shack similar
to a portable radio then yes you may bring it as long as it can be
inspected and hand carried. Large bags and or containers will not be
authorized unless previous identified on the 2012 Joint Service Open House and Air Show website.
