R-140 radio station, Soviet military shortwave radio system, commonly used during the 1960s and 1970s. This specific station was operated by the Czechoslovak People's Army, and comes in a complete set (see details below), mounted on the original ZIL-131 truck (not part of the offering, but can be sold in a set if interested). Specifications: Frequency Range: operates between 1.5 MHz and 29.999 MHz, covering a wide range of shortwave bands, and allowing it to communicate over long distances, taking advantage of the ionosphere for signal propagation Tuning and Modulation: Tuning Steps of 100 Hz (quite advanced for its time); 8 operating modes, including AM, CW (Morse code), and early forms of data transmission for teletype (e.g., Dalibor D-302). Power and Range: 1 kW transmitter, giving the R-140 had significant output strength, enabling communication over 1500–2000 km; Antennas: It comes with 3 types of antennas Power Supply: It could be powered via an external power grid or its built-in ČSAB 6-9/400 generator, ensuring operational flexibility even in remote areas Included Equipment: R-155d Receiver: A high-frequency receiver for improved signal clarity R-107 Radio Station: A smaller, complementary system for local communication Dalibor D-302 Teleprinter: For sending and receiving typed messages K-STT1 Keying Device: Used for encrypted signal modulation Included Equipment: backup R4 station, remote control, various spare parts and tooling. All equipment is functional. Contact please via email. Equipment is located about 40 minutes drive from Prague in a dry storage facility.
