The next [Billerica Amateur Radio Society] Zoom meeting will be Wednesday 4/7/21 at 7:00 PM and our guest speaker will be Bill Barber, NE1B. Bill will be doing what will be a presentation on the DMR Digital mode. I am sure this will be a very interesting and informative presentation. Please be sure join us!
