If you are using a language besides English to make a contact, you must use English when identifying your station.
As a General class control operator at a Technician station, you must identify the Technician station when transmitting on 7250 kHz with the Technician call sign, followed by the slant bar "/" (or any suitable word) and your own call sign.
Messages of a technical nature or remarks of a personal character are the only types of messages that may be transmitted by an amateur station to a foreign country for a third party.
A 10-meter repeater may retransmit the 2-meter signal from a Technician class operator only if the 10-meter control operator holds at least a General class license.
Thet name given to a form of interference that seriously degrades, obstructs or repeatedly interrupts a radiocommunication service is harmful interference.
An amateur station that simultaneously retransmits the signals of other stations on a different channel is called a repeater station.
If a repeater is causing harmful interference to another repeater and a frequency coordinator has recommended the operation of one station only, the licensee of the unrecommended repeater is responsible for resolving the interference.
If a repeater is causing harmful interference to another amateur repeater and a frequency coordinator has recommended the operation of both stations, Both repeater licensees are responsible for resolving the interference?.
If a repeater is causing harmful interference to another repeater and a frequency coordinator has NOT recommended either station, both repeater licensees are responsible for resolving the interference.
If the FCC rules say that the amateur service is a secondary user of a frequency band, and another service is a primary user, this means that amateurs are allowed to use the frequency band only if they do not cause harmful interference to primary users.
If you are using a frequency within a band assigned to the amateur service on a secondary basis, and a station assigned to the primary service on that band causes you interference, the only action you can take is to change frequencies; you may be causing harmful interference to the other station, in violation of FCC rules
