HRN 278: Remote Base (from the 2016 DCC)

/

From the ARRL & TAPR Digital Communications Conference in St. Petersburg FL, September, 2016. Lou Romero W4LT has been doing the remote for a long time - before it became the popular thing it is today. He'll tell his story, review the options for private and public remotes, club-based remotes, Off the Shelf and DIY.

This is not super-technical talk. It's more 'what the pieces are and how they go together.' Lou will demo his club's system at the end of the talk, and there's some good Q&A.
