audioguru Posted October 1, 2004 Report Posted October 1, 2004 Hi Keile,I had a quick look at Google "radio frequency allocation" with the quotes and found this neat chart for the USA that looks like a bookcase until you zoom really close to see its detail. Many frequencies are called FIXED which might include unlicensed for you.http://www.ntia.doc.gov/osmhome/allochrt.pdf Quote
