Yes, FRS (Family Radio Service) radios can communicate with GMRS (General Mobile Radio Service) radios on shared channels. This interoperability is possible due to the overlap in frequency ranges and channel designations between the two services.

Shared Channels
FRS and GMRS radios share 22 channels within the UHF (Ultra High Frequency) band, specifically:
- Channels 1-7
- Channels 15-22
These shared channels allow for communication between FRS and GMRS radios, provided they are set to the same frequency.
Power Limitations
When communicating between FRS and GMRS radios, it’s important to note the power limitations:
- FRS radios are limited to 2 watts of power on channels 1-7 and 15-22.
- GMRS radios must adhere to FRS power limitations when operating on shared channels.
Key Considerations
- Compatibility: Ensure both radios are set to the same channel and privacy code (if used).
- Range: FRS radios typically have a shorter range due to power limitations and fixed antennas.
- Licensing: FRS use is license-free, while GMRS requires an FCC license.
- Features: GMRS radios may have additional features not available on FRS radios, such as repeater capabilities.
Benefits of Interoperability
The ability for FRS and GMRS radios to communicate offers several advantages:
- Flexibility in group communications
- Compatibility between consumer-grade and more advanced radios
- Seamless integration for families or groups with mixed radio types
Limitations
While FRS and GMRS radios can communicate, users should be aware of certain limitations:
- GMRS radios must operate at reduced power on shared channels
- Some advanced GMRS features may not be usable when communicating with FRS radios
- Range differences may affect communication quality
In conclusion, FRS radios can indeed talk to GMRS radios on shared channels, providing a versatile communication solution for various outdoor activities, family outings, and group events. However, users should be mindful of power limitations and licensing requirements when operating these devices.
