One of the directions of development of noise-protected radio communication systems, including the decameter range, is associated with the use of a mode with software pseudo-random tuning of the operating frequency.

Goal – to develop a scientific and methodological apparatus for quantifying the gain provided as a result of applying this or that approach during preliminary testing of the allocated frequency resource.

The proposals on the selection of the frequency resource for the operation of multichannel radio systems in the frequency hopping mode are developed. The performance indicator for quantifying the preliminary testing of operating frequencies has been substantiated. The results of analytical modeling are presented. Formulated proposals for practical implementation.

An analysis of the use of preliminary frequency testing showed the possibility of practical gain in the presence of unusable channels in the allocated resource.
