A resilient HF linking approach can include an HF transmitting device sending an HF connection request to an HF receiving device over an HF channel. Upon receiving an acknowledgement of the request, the HF transmitting device can transmit a predefined data load to the HF receiving device. The predefined data load can be known to the HF receiving device. The HF receiving device can use the predefined data load to estimate one or more parameters of the HF channel, and send estimates of the parameter(s) back to the transmitting device. The transmitting device can use the estimates of the one or more parameters to determine a data rate for use to transmit data to the receiving device aver the HF channel. The HF channel can be a wideband HF channel. The resilient HF linking approach allows of improvement of the performance and resilience of established HF links.
