R-181-5NU MANPACK VHF BAND RADIO

R-181-5NU is a multimode radio with software defined radio (SDR) architecture which is designed to build up a radio subsystem for tactic control level as well as to exchange analog and digital information in all weather conditions. It provides for open and technically masked out radio channel in electromagnetic suppression conditions featuring increased noise immunity and security of operation (pseudorandom operational frequency readjustment, PROFR) with radio sets compatible in frequency range, modulation formats and operating modes.

Operating types:

  • analog voice reception and transmission with frequency and amplitude modulation;
  • digital voice reception and transmission;
  • data streaming and batch transmission with ARQ at rate from 9.6 to 19.2 kbps.

Operating modes:

  • single-frequency and double-frequency simplex;
  • voice information and data reception and transmission in pseudorandom operational frequency readjustment (PROFR) mode;
  • operation with a noise suppressor;
  • noiseless coding;
  • technical masking out;
  • automated radio data recording;
  • scan reception at 8 preset frequencies;
  • subscriber, group and circular type of the users’ addressing;
  • external PC control;
  • saving (standby) reception;
  • tone call transmission and reception.
