SafecomLink's Automatic Frequency Change feature, also referred to as Synchronous Frequency Hop, is a critical tool designed to enhance network efficiency and ensure that shared radio channels remain constantly available for new connections. This capability facilitates a rapid, seamless transition of an ongoing link from the crowded primary calling frequency (CF) to a designated, less congested "slot".
Operational Value and Mechanism
The system initiates a synchronous frequency hop, moving both connected stations instantaneously upon acceptance of the invitation with a single user action. By rapidly moving the Link off the Calling Frequency, Automatic Frequency Change maximizes channel availability, preventing congestion of the main channels for other stations waiting to initiate links, beacons, or broadcasts.
The feature offers flexible control over the move:
It supports a Quick hop function, which shifts the frequency up or down by standard slot increments (default 750 Hz).
It supports a Freeform hop, allowing users to specify and select an exact target frequency.
Control and Safety
Operational control is maintained through mandatory checks and built-in safety features:
The feature requires that CAT frequency control is configured on the transceiver to ensure automatic movement is possible.
Users can utilize a Frequency Sniffer to check if the proposed target slot is currently clear before sending the invitation.
SafecomLink enforces frequency compliance through an Auto-Change-Frequency Allowed Frequency List, which prevents automatic frequency changes outside of pre-approved spectral ranges.
Once the Link concludes, the software automatically prompts both stations to execute an automatic return back to the original calling frequency.
The Automatic Frequency Change feature guarantees disciplined, efficient use of radio resources. It ensures your communications move quickly off shared channels, delivering optimal speed and minimizing congestion—a non-negotiable asset for reliable tactical operations.
