Final answer:
The maximum transmission ranges for each setting vary depending on the radio type and power. The ranges can range from 1-5 km to 30-50 km.
Step-by-step explanation:
The maximum transmission ranges for each setting are as follows:
- LO (low power): The maximum range for this setting is around 1-5 km for MANPACK PRC-119 and 5-10 km for Vehicular Radio.
- M (medium power): The maximum range for this setting is around 5-10 km for MANPACK PRC-119 and 10-20 km for Vehicular Radio.
- HI (high power): The maximum range for this setting is around 10-20 km for MANPACK PRC-119 and 20-30 km for Vehicular Radio.
- PA (power amplifier): The maximum range for this setting is around 20-30 km for MANPACK PRC-119 and 30-50 km for Vehicular Radio.
These ranges are approximate values and can vary depending on factors such as terrain, atmospheric conditions, and the presence of obstacles.
