More info on R-330Zh ‘Zhitel’ Automated Jamming Station:
Station can perform discovery, direction finding and frequency jamming for satellite phones like Inmarsat and Iridium as well as conventional GSM 1900 mobile phones and NAVSTAR (GPS) receivers. The device can function autonomously and in matched pair, as the master device or as slave device mastered by R-330KMK. The station is capable to completely suppress the radio signal within 20—30 kilometers radius.
The station kills entire frequency range, including the friendly transmissions. Therefore, before its launch a notification of complete radio silence and turning off of all the radio emitting equipment is broadcasted. The electronic protection systems cannot detect the station after it is turned on because it will simply suppress the signal of EP devices. If the enemy uses beam riding guidance missiles against R-330Zh, the station uses its own radio interference devices to lure the missiles out.

Can ‘ordinary coal miners and former truck drivers’ really use such a sophisticated equipment?
