Abstract
Techniques for selecting frequencies of operation are described. HF signals may land at the receiver node with power levels dependent upon the transmit frequency. The frequency with the highest power level at the receiver node may be selected when the receiver node is not subject to interference. The receiver node may be unable to receive a desired signal if an interfering signal has a signal level which is higher than the desired signal. The interfering signals may have a signal level which is higher across all available frequencies. The transmitter node may determine a potential relay table with a communication link between the transmitter node and a relay node and a communication link between the relay node and the receiver node. The communication link may include link margins above the interfering signal, ensuring the links may be established. The nodes may then communicate even when subject to interference.
