Final answer:
The AN/PRC-112 radio's beacon function uses VHF frequencies, but the specific MHz frequencies are not provided in the question and such details are typically found in the technical manual or specification sheet, which may be controlled or classified.
Step-by-step explanation:
The question is asking for the specific MHz frequencies contained in the beacon function of the AN/PRC-112 series radio. The AN/PRC-112 series radio is a multifunctional survival radio used by military aviators, primarily for combat search and rescue operations. The beacon frequencies for such radios are typically in the very high frequency (VHF) range, but the student's question does not provide enough information to specify which frequencies the AN/PRC-112 uses. In general terms, VHF frequencies range from 30 MHz to 300 MHz, and beacon functions would typically use a subset of these frequencies to transmit a distress signal.
It is worth noting that while I can provide general information on typical frequency ranges, the exact frequencies for the beacon of the AN/PRC-112 series radio would require reference to the radio's technical manual or specification sheet, which often contains classified or controlled information not publicly available.
