Understanding Radio Nets

Derek Noll | February 7, 2026

Intro

Radio nets have been a staple in amateur radio and GMRS groups for decades, with amateur radio having a more extensive network. These nets span various radio bands and clubs, serving multiple purposes, including fostering on-air camaraderie, facilitating discussions on specific topics, and ensuring emergency preparedness.

In local amateur radio clubs, weekly nets like the Four-State Net, hosted by the Antietam Radio Association in Hagerstown, Maryland, are popular. On the HF band, numerous nets operate, with one notable example being the Hurricane Watch Net, which remains active during hurricane season. Blackskye Community Radio Association (BSCRA) operates weekly and contingency nets, including the Neighborhood Readiness Net and ALERT Safety Net, on the GMRS band. 

This article aims to provide residents of our serviced communities with an overview of the nets sponsored by Blackskye Community Radio Association. It will explain the purpose, community benefits, participation, and limitations.

Purpose

Neighborhood Readiness Net

The BSCRA Neighborhood Readiness Net is held every Monday at 8:00 p.m. on GMRS frequency 462.650 MHz, which is channel 19. The DCS tone used is 411. The purpose of this net is to share general announcements related to the organization and local communities, monitor repeater coverage and community participation, and provide an opportunity for community members to practice using their radios while communicating in a coordinated manner. 

ALERT Safety Net

The BSCRA ALERT Safety Net operates on frequency 462.650 MHz and uses a DCS tone of 411. This net is activated during severe weather events and other situations that pose safety risks to our communities. Its primary purpose is to provide situational awareness by gathering and relaying real-time information such as weather conditions, infrastructure impacts, power outages, road hazards, and general safety concerns. By sharing accurate and timely observations, the net helps community members make informed decisions, stay informed about changing conditions, and look out for one another when normal information sources may be limited or disrupted.

Repetition through practice is crucial in effectively responding to and mitigating stressful events. A radio net offers an excellent opportunity to practice using one’s radio equipment, ensuring its operational soundness. Additionally, it provides a chance to communicate with the net control station and familiarize oneself with other community members participating in the net. 

Weekly nets may sometimes feel redundant and unproductive, but it’s the repetition and ongoing participation that prepare individuals for impactful events. 

Community Benefit 

Our mission is to ensure safe communities by providing citizens with backup communication methods for use when everyday cellular and internet communication fails. We often assume that during widespread emergencies, these systems will remain operational, but history has shown us that this isn’t always the case. These systems can fail, leading to an information blackout that hinders situational awareness. If your iPhone and internet become unusable, how would you access real-time, local information? How would you call for help? How would you stay connected to family, friends, and neighbors? The nets conducted by BSCRA fill the gap left when primary communication methods fail.

The nets sponsored by BSCRA are conducted by volunteers who reside in our communities. 

How Nets Are Conducted

Our nets are coordinated on-air by a net control station operator, who is a member of BSCRA. This central point of contact ensures coordinated operation during the net. Typically, the net control station operates on a base station radio with backup power, backup radios, and antenna systems, and with higher transmit power. Some stations may even have access to satellite internet, like Starlink, which can remain operational even when regional internet services are down. This satellite internet provides a net control station with information not readily available to community residents in affected areas, enabling them to disseminate information to other participants in the net. Moreover, our net control stations may be licensed to operate in the amateur radio spectrum, allowing them to monitor their nets and engage in information sharing for enhanced situational awareness. 

All nets are standardized using scripts available on our website. This ensures that everyone follows and practices the same radio procedures, making the process familiar which is crucial during stressful events.

How To Participate

All nets sponsored by BSCRA are conducted as community service and are open to anyone with a GMRS license. While membership is encouraged, it’s not mandatory to participate. We strongly encourage all residents of our communities to get involved by acquiring at least a low-cost handheld transceiver. This will give you an extra layer of preparedness for personal or family response plans. 

Once you have a GMRS license and radio, you simply tune into the designated frequencies on the nets at the specified times. Follow along and join in. The nets are relaxed and exist to be helpful and reduce stress, so please don’t be afraid to make mistakes or say the wrong thing during a net. We are always here to be friendly and helpful. 

Limitations

BSCRA is committed to being a dependable community service organization that fulfills its purpose during times of community need. As a volunteer-based organization, we may not always have members available to serve during our weekly nets or contingency nets during severe events impacting our communities. Our reliability hinges on community involvement and a strong network of members and volunteers. The greater the community involvement, the stronger our network becomes. 

Our nets are designed to bridge the communication gap caused by the failure of conventional communication methods. However, they are not a substitute for emergency services or calling 911. In any emergency, 911 should always be your first call. If calling 911 is not possible, we will make every effort to get the necessary resources to you.
