VHF-FM range is standard. The IF is 465 KHz and 8.4 MHz. Sensitivity 200 µV in AM and 20 µV in the FM path. Selectivity 36 ... 46 dB in the AM path and 26 dB in FM. The receiver has an internal magnetic antenna for AM reception and a built-in dipole for VHF-FM reception. The rated output power of the ULF is 2 W, the maximum is 4.
