SP851 – How to Improve Radio Reception & Reduce Static

If your FM or DAB+ radio has static, cuts out, or has weak reception, try these steps in order.

Step 1 – Fully Extend the Antenna

Extend the SP851 antenna all the way. Then slowly change the antenna’s position while listening to the station.

A fully extended antenna is important for both FM and DAB+ reception.

Step 2 – Move the Radio Near a Window

Move the SP851 closer to a window or open area, then listen to the same station again. Walls, buildings, and enclosed rooms can weaken radio signals.

Reception gets better? The SP851 is working. The original location has a weaker signal, so keep the radio closer to a window or another open area.

Step 3 – Move Away from Electronics

Keep the SP851 several feet away from Wi-Fi routers or mesh units, TVs, phones, computers, and other electronic devices that may cause interference.

Step 4 – Move Away from Metal

Do not place the SP851 directly on or next to large metal objects or surfaces. Move it to an open table, shelf, or another location, then test again.

Step 5 – Try Another Station

Try several FM or DAB+ stations.

Only one station has poor reception? That station’s signal may be weak in your area.

Several stations have poor reception? Move the SP851 to another location, preferably near a window, and test again.

Something Doesn’t Look Right?

Reception Improves When I Move the Radio

The original location likely has a weaker radio signal or more interference. Keep the SP851 where reception is strongest.

Reception Is Poor Even Near a Window

Try several stations. Radio reception depends on signal coverage in your area and can be weaker in rural locations, inside some buildings, or far from a station’s transmitter.

DAB+ or FM Works Better Than the Other

This can be normal. DAB+ and FM use different broadcasts, so reception strength may be different in the same location. Fully extend the antenna and find its best position for the station you want to hear.
