In addition, foreign amateurs whose administrations recognize our Amateur service licensing structure and have entered into a treaty arrangement with the U.S. State Department are authorized to operate their amateur transmitters in areas regulated by the Federal Communications Commission. These amateurs are now licensed by rule and are no longer required to file FCC Form 610-A or receive an additional
"reciprocal permit" from the U.S. See Sec. 97.5(c) and 97.107
They identify their stations with the U.S. call area followed by the words "fixed, portable, mobile or "slant" (or the slant bar on CW) and the station call issued by their home country. (For example: W1/XE1AAA) See Sec. 97.119
Under a May 1952 treaty arrangement, Amateurs licensed in Canada are considered to also be licensed in the United States and use their Canadian call signs on the air. They signify their U.S. location by using the words "fixed, portable, mobile or slant" when operating in the voice mode (or the slant bar on CW) followed by the U.S. call area. (For example: VE1AAA/W1). The various call sign
areas are listed underneath the call sign prefix information.
In addition, foreign radioamateurs holding a CEPT license (issued by a country belonging to the European Conference of Postal and Telecommunications Administrations)or an IARP (International Amateur Radio Permit)are licensed by rule and also may operate their amateur radio equipment in the U.S. See Sec.97.5(d) and 97.5(e)
Class 1 CEPT and IARP licensees have all (that is, those of an Amateur Extra Class operator) U.S. frequency privileges. See Sec. 97.301(b). Class 2 CEPT and IARP license holders are restricted to operating on frequencies above 30 MHz. See Sec. 97.301(a)
