Serving Dodge County and Nearby Wisconisn Counties Since 1930
Bringing hams and other radio enthusiasts together for learning, service, and fun!
Discover licensing help, emergency communications, public service, training, and a welcoming club community.
Our original ARES (Amateur Radio Emergency Services) EMCOMM (Emergency Communications) trailer was destroyed in a tornado in May of 2025. Our new ARES EMCOMM Trailer was delivered in April of 2026. Volunteers have been working diligently to prepare the trailer for both emergency and educational use.
CONSIDER VOLUNTEERING to help prepare it for service to our community. If you are interested in Emergency Communications, either contact us via Facebook or consider attending our monthly meeting on the first Tuesday of the month. We meet at Mike DeJager’s (KB9LXP) at 111 N High Street in Randolph, WI. A monthly program is at 7 PM followed by a business meeting. Everyone is welcome and you do not need to be a ham radio operator to attend. Youth are welcome too.
EMCOMM – Emergency Communications
Training, preparedness, and real-world support for public service and severe weather events
🌩️ RRRC Weather Net
When severe weather threatens our area, the Rock River Radio Club activates our Weather Net to provide real-time, ground-level reports that can make a difference.
Our trained amateur radio operators monitor conditions across Dodge County and surrounding areas, relaying critical information such as:
Tornado sightings and funnel clouds
Hail size and accumulation
High winds and storm damage
Flooding and hazardous road conditions
These reports are shared over our repeater and, when appropriate, passed along to organizations like the National Weather Service and local emergency management officials.
👥 Who Can Participate?
All licensed amateur radio operators are welcome to check in and participate during an active Weather Net. Even if you’re not a trained spotter, your report may still be valuable.
If you’re interested in becoming more involved, we encourage participation in our training events and public service activities.
What is a ham radio net?
A ham radio “net” is an organized on-air gathering of amateur radio operators who meet on a specific frequency (or repeater) at a scheduled time for a common purpose.
Think of it like a radio-based group meeting.
Common purposes include:
Passing information
Emergency communications practice
Social conversation
Technical discussions
Weather spotting
Training and announcements
Traffic/message handling
Most nets have a Net Control Station (NCS) — one operator who helps direct the conversation and keeps things orderly.
