MRA-3

MRA 3

MRA-3 memory radio analyzer is a unique radio receiver designed for instant disclosure of radio bugs running in wide range of radio frequency spectrum. MRA-3 selectively eliminates even strong local TV and radio broadcasting, or mobile and data transmitters, using a unique frequency processing combined with extra fast spectrum comparisons. Checked "bugs free" spectrum is stored in the background memory and compared with actual signals every 6 seconds. A new suspicious signal activates a 3-level alarm mechanism. The new signal is also recorded in a separate alarm memory.
