Heterodyne indicator of resonance `` GIR ''.

Instruments for adjusting and controlling the PTA.Since 1976, the GIR heterodyne resonance indicator has been produced by the Kursk Mayak plant. "GIR" is intended for tuning various radio equipment, such as radio receivers, radio transmitters, televisions, antennas and other HF devices). "GIR" provides a frequency generation range up to 80 MHz, covered by replaceable coils and the following fixed frequencies: 161; 249; 386; 465; 562; 912; 1480 kHz, provided by seven exchangeable coils. Smooth tuning to the resonant frequency of the tuned circuit is made by rotating the knob with the scale and according to the dial indicator. Frequency setting error + -3%. The output voltage is not less than 0.1 V. Power supply from the mains through the power supply unit. Power consumption 10 watts. The dimensions of the device are 145x67x70mm. The dimensions of the power supply are 145x45x48 mm.
