The test came on the equipment of the Polish Army in the late 60s last year. Century with the introduction into service of new types of radio mobile R-105M, R-107, R-108M, R-109m and was used to study: receiver sensitivity, frequency , deviation transmitter voltages. It can be used to study other radio and FM receivers in the frequency range from 20 to 52 MHz.
With the additional equipment it was also possible examination of other radio parameters than allowed for this same test (eg. current equivalent of antenna).
