RX2050 - EPM receiver
RX2050 receiver is a device intended for installation in mobile devices. It ensures reception of RF signals from transceivers operating in 25 MHz to 146 MHz fixed frequency band. Transceiver modulation in 30 MHz to 108 MHz band meets the requirements of STANAG 4204 standard. In other bands, the receiver is capable of receiving signals from RF2050 or other transceivers that are compatible with the RF2050 in terms of modulation at these frequencies. The RX2050 receiver also receives signals in frequency hopping mode and it is fully compatible with the RF2050 and RF20 transceiver modes. The receiver includes an effective co-site filter that allows simultaneous operation of the RX2050 receiver with RF2050 transceivers in a single vehicle in 30 MHz to 90 MHz operating band. The condition of compatible operation is the distance between recommended vehicle antenna types of at least 1.5 m and receiving and transmitting frequencies differing by at least 10 %. The RX2050 receiver is not designed for data transmission.
a) in all operation modes
• built-in test equipment (BITE) with error indication on the transceiver display;

• emergency erasure of operating data on fixed frequency channels including encryption unit codes and information for FH networks, including TRANSEC and COMSEC;
• switching on/off of acoustic signaling by transceiver operators;
• backlit display and keypad;
• adjustable display contrast;
• operating channel signal reception signaling by a LED on the transceiver panel;
• whisper mode with reduced audio frequency output power;
• received signal loud monitoring with volume regulation and LED monitor signaling;
• service information display – firmware;
• remote receiver control via REMOTE connector and RS232 or RS485 communication link and PRC20 protocol;
• simple control.
b) in fixed frequency operation
• up to 10 channel presents from the entire 25 MHz to 145.9875 MHz frequency range, number of preset channels is reduced when occupied by FH networks;
• simplex reception;
• 150 Hz sub-tone squelch or signal squelch (only signal in VHF II);
• reception via built-in encryption unit compatible with RF13, RF20, RF2050;
• reception of short coded messages – FLASH with opposite transceiver identification;
• keypad channel programming;
• fixed frequency channel preset scanning;
• operating frequency setting in 6.25 kHz. 8.33 kHz, 25 kHz or 1 MHz steps.
c) in FH operation
• up to 6 network presets;
• operation in 30.000 MHz to 87.975 MHz frequency range;
• secured TRANSEC operation and encrypted COMSEC operation;
• compatible with RF20, RF2050, RF23 and RF2350 transceivers;
• HLC, HLG and 121.500 MHz (HLA) frequency monitoring;
• optional frequency hopping operating modes – FH, DFF, FCS and MIX with quick transition to HLC, HLG or HLA reception;
• reception of alert message to all network users;
• reception of selective communication from MASTER transceiver;
• reception of short text messages (maximum 156 characters);
• INTERLEAVING switching off for close-to-the-limits communication.
