January 2026 Membership Meeting - Room A207

​

Where Did My Signal Go ?

 

The ionosphere is an amazing phenomenon that makes our long-distance amateur radio communications possible.   We will discuss the ionosphere and its regions to understand how each one either helps or hinders our communication.  We’ll find out why 75 meters is useless during the day but reaches halfway around the world during the night, or why 40 meters is dead during the day at the same time you are working into Europe on 10 meters.  The presentation will stay at a practical level and explain how we can use the ionosphere to our advantage.  It will not include mind numbing math or calculus, molecular physics, graphs or charts, nor a quiz at the end.
