Latihan Soal Unar Tingkat Siaga

The correct answer is Bahasa Indonesia dan Bahasa Inggris. This means that the allowed communication languages are Bahasa Indonesia and Bahasa Inggris.

The correct answer is "memanggil siapa saja yang mendengar." This is because "CQ Calling CQ Calling" is a procedural phrase used in radio communication to signal that the speaker is calling for anyone who is listening to respond. It is a general call to all stations and not directed at a specific station.

The correct order of radio station setup is Power Supply – Transceiver – SWR – Antenna. The power supply is necessary to provide electricity to the system. The transceiver is responsible for transmitting and receiving signals. The SWR (Standing Wave Ratio) is used to measure the efficiency of the antenna system. Finally, the antenna is the device that sends and receives radio waves.

The given answer states that the frequency allocation in the 2-meter band from 145.800-146.000 is used for satellite communication. This means that this frequency range is reserved specifically for satellite communication purposes and cannot be used by beginners or for emergency purposes.

The given correct answer states that the frequency allocation in the 2-meter band from 145.800-146.000 is not allowed for simplex communication, but rather for communication through satellites. This means that the frequency range is designated for satellite communication and not for direct point-to-point communication. Therefore, it is not permitted to use this frequency range for simplex communication.

The correct answer is "Prefik, kode wilayah, dan sufik." This means that the correct order of mentioning call signs is starting with the prefix, followed by the area code, and ending with the suffix.

The correct answer is "Semua Benar" (All are correct). This means that all the given frequency ranges (3.500 - 3.900 MHz and 7.000 - 7.035 MHz) are part of the YD bandplan for the HF band. This implies that radio communication activities within these frequency ranges are allowed and regulated according to the YD bandplan.

If a candidate for Amateur Radio Level Alert already has a Limited Radio Operation Certificate and a General Radio Certificate issued by the Directorate General, then they are exempt from the obligation to take the Amateur Radio proficiency exam.

The correct answer is 144.000-148.000 MHz. This is because the bandplan for VHF specifies that the frequency range allocated for this band is from 144.000 MHz to 148.000 MHz. Therefore, any frequency within this range can be used for VHF communication. The other options provided, 144.000-146.000 MHz and 142.000-149.000 MHz, do not fall within the specified bandplan for VHF.

The given answer suggests that the "laporan pancaran 599" has a readability score of 5, a signal score of 9, and a tone score of 9. This means that the report is somewhat difficult to read or understand, but it has a strong signal and a positive tone. The high signal score indicates that the report contains important or valuable information, while the high tone score suggests that the report is positive or optimistic in nature.

Radio frequency with a wavelength of 0.75 meters falls within the Ultra High Frequency (UHF) range. UHF frequencies typically range from 300 MHz to 3 GHz, and are commonly used for television broadcasting, satellite communication, and various wireless devices such as cell phones and Wi-Fi routers.

The given block diagram shows a receiver, and block G is labeled as the "Local Oscillator." The local oscillator is an essential component of a receiver that generates a stable frequency signal. It is used to mix with the incoming signal to produce an intermediate frequency for further processing and demodulation. The local oscillator plays a crucial role in tuning and selecting the desired frequency for reception.

The procedural code 'CQ yb0zz' is used to indicate that the station is calling or trying to make contact with the station with the call sign 'yb0zz'.

The correct answer is "Dari atau this is." This is because the phrase "Dari atau this is" in Indonesian translates to "From or this is" in English. In Morse code, each letter or word is represented by a specific combination of dots and dashes. Therefore, "Dari atau this is" is the correct translation for the Morse code signal "Yb0zz de yb0zcd."

The correct answer is 144.000-148.000 MHz. This range of frequencies is allocated for Continuous Wave (CW) emission in the Very High Frequency (VHF) band.

The wavelength of a wave is inversely proportional to its frequency. Given that the frequency is 150 mHz, which is a very low frequency, it can be inferred that the wavelength would be relatively long. Among the options given, 50 cm is the longest wavelength, making it the most suitable answer.

Propagasi ground wave adalah jenis propagasi gelombang radio yang terjadi melalui permukaan bumi. Dalam propagasi ground wave, gelombang radio dapat merambat langsung ke penerima (direct wave), dipantulkan oleh permukaan bumi dan mencapai penerima melalui pantulan tersebut (ground reflected wave), serta merambat sepanjang permukaan bumi (surface wave). Oleh karena itu, semua pernyataan yang disebutkan dalam jawaban (direct wave, ground reflected wave, surface wave) adalah benar dalam konteks propagasi ground wave.

The correct answer is "Kepala Dinas Provinsi". This is because the Ujian Amatir Radio is organized by the head of the provincial department, who is responsible for overseeing and managing the examination process. The other options mention individuals such as the Governor or the Chairman of the ORARI Regional, but they are not directly responsible for organizing the examination.

ORARI (Organisasi Amatir Radio Indonesia) is a national reserve in the field of radio communication. This means that ORARI serves as a backup or reserve in case of emergencies or disruptions in radio communication. ORARI also plays a role in advocating for the rights of amateur radio operators both nationally and internationally.
