Repeater Access and Conditions of Use
The REACT3310 GMRS Repeater is a privately owned and operated radio communications facility established to support family communications, encourage responsible use of the General Mobile Radio Service (GMRS), and promote the tradition of Class A Citizens Band Radio.
Authorization to access and use this repeater is granted solely at the discretion of the repeater owner. Individuals seeking access may submit a request through the myGMRS website. Submission of a request does not guarantee approval. The owner reserves the right to approve, deny, suspend, or revoke access privileges at any time.
Use is restricted to operators authorized under a valid FCC GMRS license, including eligible family members operating under that license as permitted by FCC rules. All users must comply with 47 CFR Part 95, Subpart E and any additional operating guidelines established by the repeater owner. Courteous operation and proper radio etiquette are expected.
Access is provided free of charge. No membership dues, subscription fees, or payments are required for authorized use.
The repeater is provided as an as-available community communications resource. Continuous operation, coverage, or availability is not guaranteed. Access may be interrupted, restricted, or discontinued without prior notice because of maintenance, equipment issues, technical conditions, or decisions by the owner.
REACT3310 is not a substitute for emergency services or a guaranteed emergency communications system. Users should maintain alternative methods of communication when reliability is essential.
By using REACT3310, operators agree to comply with these conditions of use.

Operating guidelines & being a good radio neighbor
REACT3310 is part of a wider GMRS community. Our repeater is a shared communications resource, and thoughtful operating practices help everyone enjoy the service.
- Identify with your FCC-assigned GMRS call sign as required by FCC rules.
- Keep transmissions courteous, family-friendly, and respectful of other operators.
- Listen before transmitting, pause between transmissions, and leave room for others to join or request assistance.
- Keep conversations reasonably brief when others are waiting, and give priority to urgent communications.
- Follow FCC Part 95, Subpart E, and the repeater owner's operating instructions.
Be a good co-channel neighbor
Other GMRS repeaters and stations in our region may operate on the same frequencies. The REACT3310 repeater output is 462.675 MHz, and its input is 467.675 MHz. These are shared GMRS channels, not frequencies reserved exclusively for one repeater or group.
A quiet speaker does not always mean a clear channel. Many radios use CTCSS or DCS receive squelch to mute transmissions that do not carry the selected tone or code. Motorola calls its CTCSS system Private Line (PL), a Motorola trademark. Despite the name, PL does not make a channel private, prevent interference, or give one operator priority over another.
Before transmitting: Listen on the repeater output frequency. Use your radio's MONITOR function or temporarily turn off receive PL/CTCSS/DCS tone squelch so you can hear other activity that your radio might otherwise mute. If the channel is occupied, wait for a clear opportunity rather than transmitting over another conversation. When practical, also be mindful of activity on the repeater input frequency.
Monitoring helps, but it cannot reveal every distant station or hidden transmitter. If interference occurs, stop, listen, and cooperate with other users to minimize disruption. Restore your normal receive settings when appropriate; do not change the repeater access/transmit tone unless instructed by the owner.
Be a good neighbor. Enjoy the GMRS community. Together, let's preserve this valuable radio service for future generations.

From Class A Citizens Band to GMRS
The General Mobile Radio Service traces its roots to the Class A Citizens Radio Service, established in 1949. Unlike the familiar 27 MHz Class D CB radio service, Class A used UHF frequencies and supported practical two-way communications for individuals, families, and other eligible users.
In 1976, the FCC redesignated Class A as the General Mobile Radio Service (GMRS). Over time, the service evolved toward personal and family communications, with repeaters helping extend coverage beyond direct radio-to-radio range. Today, GMRS remains a licensed service regulated by the FCC, and REACT3310 celebrates that Class A heritage.

How to Get Your GMRS License
Interested in joining the GMRS community? Getting licensed is straightforward. No examination is required. An individual GMRS license generally covers the licensee and eligible immediate family members under FCC rules.
Create your FCC account
Visit FCC CORES to register and obtain an FCC Registration Number (FRN), if you do not already have one.
Apply for a GMRS license
Use the FCC Universal Licensing System (ULS) to apply for a new GMRS license (radio service code ZA). Follow the FCC's current application and payment instructions.
Receive your call sign
Once the FCC grants your application, look up your license and call sign in ULS. GMRS licenses are generally valid for 10 years. Follow FCC identification and operating rules.
Eligibility: Individual GMRS applicants must generally be at least 18 years old and not representatives of a foreign government. Check the FCC rules for details on eligible family members and permitted operations.
FCC application fees and procedures may change. Confirm the current fee and instructions on the FCC GMRS information page before applying. For the full rules, see 47 CFR Part 95, Subpart E.
FCC GMRS rules and licensing
GMRS operation is regulated under 47 CFR Part 95, Subpart E. Transmitting through REACT3310 requires appropriate GMRS licensing or authorization under the applicable family-license provisions. Repeater access is free, but FCC licensing requirements still apply.
Read the official FCC GMRS rules
Key topics include who may operate (§95.1705), permissible uses (§95.1731), station identification (§95.1751), and GMRS channels (§95.1763). FRS is a separate, license-by-rule service; standard FRS radios cannot transmit on GMRS repeater input channels.
GMRS channels, repeater pairs & CTCSS tones
The General Mobile Radio Service (GMRS) includes 30 frequency channels under FCC rules. The chart below separates simplex frequencies from the eight standard repeater pairs. Frequencies are in MHz. On repeater channels, listen to the 462 MHz output and transmit on the corresponding 467 MHz input.

*Channel numbers 1–30 follow a commonly used consumer-radio convention; programming labels can differ by manufacturer. A dash means there is no standard repeater input for that row. GMRS operating and equipment restrictions vary by frequency; consult the FCC rules.
Common PL / CTCSS tone reference
Examples of commonly encountered analog CTCSS tones (in hertz):
Important: These are examples, not assigned or recommended tones for any particular GMRS channel or repeater. A repeater may require a different CTCSS tone or a DCS code, and its input and output tones may differ. Use the exact settings published or supplied by that repeater's owner. For REACT3310, obtain current access settings from the repeater owner.
Tones and repeater access settings are subject to change. For current information, consult myGMRS.com or RadioReference.com, and confirm with the repeater owner before programming or transmitting. Tone squelch does not make a frequency private: monitor for other co-channel users and operate courteously.
Regulatory reference: 47 CFR §95.1763 — GMRS channels.
FRS channels and frequencies
The Family Radio Service (FRS) provides 22 shared simplex channels. The following table lists FCC channel center frequencies and maximum effective radiated power (ERP) for certified FRS radios. These are FRS simplex channels, not repeater programming instructions.
Source: 47 CFR §95.563 — FRS channels and §95.567 — FRS power limits. Maximum ERP is 0.5 W on channels 8–14 and 2 W on channels 1–7 and 15–22.
