BEECN UHF radios operate on line-of-sight. That can make comms in SW Portland's hilly neighborhoods challenging. To work around this issue, PBEM has fielded a UHF repeater in SW Portland for BEECN. The repeater is stored near [https://maps.app.goo.gl/2xLFWBdx9KiBUsKM9 Markham Elementary School], with the intention that it would be deployed in the field behind Markham ES if a crew of volunteers can access it and stand it up. The purpose of this article is to describe equipment specifications, and the deployment, set up, and demobilization of the BEECN repeater. | |||
