Overcoming Interference During a Mount Everest expedition
In a Mount Everest expedition emergency, your radio is your only link to help. But near the Mount Everest summit, visual obstructions and atmospheric interference make communication a physical challenge.
VHF radios require a direct line of sight. The massive ridges around the Mount Everest summit can block signals to Base Camp, requiring 'relay' stations during any major Everest trekking peak expedition.
With less atmosphere to shield from space weather, solar activity can create static on the channels used by Mount Everest summit teams. Understanding these cycles is part of expedition leadership training.
Every Mount Everest expedition member should carry a spare battery against their skin. If your radio dies in the cold, you are invisible to your team on the Mount Everest summit ridge. Comms are life.
A silent radio is a dangerous thing. Master the physics of communication to ensure your Mount Everest expedition stays connected and safe toward the summit.
