Верно. Это потому-что Россия подписала "радиолюбительские протоколы CEPT" и в результате этого оказалась в вот в этой "подгруппе":
"If the country of which you are a citizen and an amateur licensee has entered into a multilateral operating agreement with the US, CEPT or IARP, no additional permit is required -- simply bring your CEPT or IARP documentation when you visit the US. Identify your station by the US call district identifier, such as W3/G1ABC. Use "W" and the number of the FCC call letter district in which you are operating followed by a slash and your home call sign (plus any other CEPT or IARP requirements). Amateurs must be a citizen of the country in which they are licensed. Check these links for a list of the US call districts shown graphically or for a text listing. And make sure to check the current information with the FCC. This is intended for short visits."
А до подписания была в этой:
"If your country of citizenship and amateur license is not named in lists of countries that have such agreements with the US, then no operating agreement is in effect between the US and that country--and operation is not possible in the US based on your home license. Should you wish to seek such an agreement between your home country and the US for the future, you may want to contact your national Amateur Radio society to request that they contact the responsible government official to request such an agreement with the US. US citizenship is not required to obtain a US license, but a US mailing address is. Once a person is prepared to take the US license examinations, licensing is possible in as little as a few days to a week. If a US license is held, no other reciprocal operating authority may be used for operation in the US"
