Federal Agencies

Federal Agencies Overview Regarding Surveillance Frequencies With regards to federal agencies, it is difficult at times to separate what is "surveillance" from other operations. If you come across a frequency that appears to be used primarily for surveillance operations, it will not be published here. If it is a mixed bag, and you feel it shouldn't be posted, please it to the database submission forum, and we will, at our discretion either post it or remove it.
