Hi, I am looking for a detailed spectrum allocation guide for the US. Im not talking the default "US Frequency Allocations Chart." but something more like a book or guide. Does such a thing exist?

Does such a thing exist? That data is scattered all over the place at the moment, and we've had to spend a large amount of time digesting and marking it up. We'll post our code and tidy XML representations of the data soon. Generally speaking, the sources you would have to dig through to get the full details of US spectrum allocations are: 1) The FCC regulations, 47 CFR, contain band allocations, power restrictions, etc.: http://www.access.gpo.gov/cgi-bin/cfrassemble.cgi?... 2) Additional information on federal band allocations can be found in the NTIA Redbook: http://www.ntia.doc.gov/osmhome/redbook/redbook.html 3) Most allocations to non-Federal organizations are in the FCC Universal Licensing System. You can download the entire contents of this database as delimited text files, but they're an amazingly awful mess and require substantial pre-processing. http://wireless.fcc.gov/uls/index.htm?job=transact... 4) AM, FM, and TV broadcast stations are in the FCC CDBS, which is not nearly as bad as ULS: http://www.fcc.gov/mb/databases/cdbs/ 5) Shortwave broadcast stations are on the FCC HF Broadcasting site: http://www.fcc.gov/ib/sand/neg/hf_web/seasons.html 6) Federal allocations are listed in the NTIA Government Master File. This is a classified database, but we managed to get half of the GMF records in a FOIA request last summer, and we'll be requesting an updated and expanded version. 7) Some additional information is available in the FCC IBFS, COALS, and Equipment Authorization databases, and in various DISA JSC databases.
