Four-Band Radio Test Signal Generator

Bring a selectable RF test signal to a compatible radio-repair bench. This four-band generator combines a frequency display with internal tones, Bluetooth audio and an external input for planned receiver-testing and alignment work.

✅ Choose the band for the receiver check - LW, AM, SW and FM selections cover different test arrangements.

✅ Read the selected frequency - The OLED display keeps the setting visible while you prepare the test.

✅ Choose the modulation source - Internal tones, Bluetooth audio and external input provide several signal-source choices.

✅ Use a portable power arrangement - A compatible 18650 cell supplies the unit away from a fixed bench source.

Give the Receiver a Known Test Source

Radio troubleshooting is easier to organise when the receiver is presented with a planned signal rather than only whatever broadcast happens to be available. A generator lets you choose the band and source, then observe the receiver's response.

Use only in an appropriate test arrangement and follow the equipment's connection and radio-use requirements. The battery is not included. Charge through a standard 5 V source only; the product instructions exclude 9 V and 12 V fast-charger supplies.
