WebThe VLF Receiver has a tuning range of about 12 kHz to 35 kHz, requires a supply of 15 Volts DC at 35mA, and provides output signals at 0 – 2.5 Volts and 0 – 5 Volts. It is … WebDec 24, 2015 · This converter transfers reception of the VLF band to 10 MHz (30 meter band). So I should tune my receiver to 10000 + 17.2 = 10017.2 kHz to receive SAQ. The other way around: when my receiver display shows a frequency of 10.077.5 kHz, I’m actually listening to 77.5 kHz, which is the DCF77 transmitter in Germany.
