The TW-1 Talking Wattmeter returns to LDG’s product line-up and is now available from authorised UK amateur radio retailers, including Martin Lynch & Sons, for around £160.

Intended primarily for visually impaired radio amateurs, this unique instrument speaks the RF power level and SWR aloud over a self-contained speaker.

On command, this wattmeter speaks the forward or reverse power level in watts, or the SWR. A constant Tone Mode is also available, indicating the power or SWR as a varying pitch, making the TW-1 ideal for tuning manual antenna tuners or valved transmitters or amplifiers. It’s also great for mobile operation, allowing the user to tune screwdriver-type antennas while safely watching the road.
