If you don't know who called whom, it is difficult to determine the significance of a network's nodes, and impossible to target them properly.
The modern HF environment is a challenge for COMINT - SIGINT systems. There are many dozens of active calling systems (ALE, ALM, ALIS, ACS, Selcall...). All of our competitors provide you with solutions to three of them, and for no variants thereof.
We build solutions for the real-world, the actual variants and systems in use by targets of intelligence interest, and so we offer dozens of decoders for these important calling systems.
