How do I stop interference on my FM radio?
A change of aerial height may also reduce the effect. A higher performance aerial can help lessen interference caused by nearby radio transmitters. If you have an aerial amplifier, use the lowest gain amplifier needed, to avoid possible system overload caused by the nearby transmitter.
How do you reduce SDR noise?
To reduce RFI, the tip recommends disconnecting the shield connection of the USB cable from the ground connection of the RTL-SDR dongle. This overcomes a design flaw in the RTL-SDR which allows the shield of the USB extension cable to act as an antenna, causing unwanted RFI.
How do I reduce background noise in HF?
The best way to combat noise is to use a transceiver with noise-reduction technology. Barrett Communication’s 4050 HF SDR transceiver uses digital signal processing (DSP) to remove the background noise from the signal you want to hear.
