The ECOMM drill
I have always been a proponent of relaying messages because I realize that even HF has limitations. It's dependent on propagation. There's ground wave and skywave. Groundwave is straight radio to radio direct communication where the radio waves travel along the ground. Skywave is when the signal hits the ionosphere and 'skips' and bounces back to the ground. You can be either inside or outside of the skip zone. Enter the relay which nets use. You simply have someone in between you that has contact with you and the person you are trying to contact simply relay the message. A net I am on counts a relayed in check-in as a legitimate check in even though he could not contact net control. Most nets do this. A decade or maybe more ago I was on a certain ham radio forum and decided to organize an ECOMM drill and see how fast we could relay a message across the country to HI and give a reply back to the point of origin. On top of this all participants were supposed to get t...
