LDG Electronics TW-1 Talking SWR/Wattmeters
LDG Electronics TW-1 Talking SWR/Wattmeters provide an aural spoken indication of power and SWR using a digitally recorded voice. It is ideal for the visually impaired or for those times when you need to look elsewhere while still obtaining power and SWR measurements. At the press of a button, the TW-1 speaks the forward power, reverse power or SWR. Three languages are available: English, Spanish and German and it includes an internal top firing speaker; no external audio hookups are needed. The TW-1 also offers a continuous tone mode for tuning. Simply press and hold the Forward button and a tone indicates power. As you adjust your amplifier or antenna tuner, a higher tone indicates higher power. This is perfect for peaking your amplifier while keeping a close watch on the grid current. You can select either long or short voice reports (verbose or terse modes). Long reports include descriptors like "thousand" or "hundred" and end with "forward watts" or "reverse watts". Short reports speak only the numerical value of the measurement you've selected for a quick reading. The TW-1 needs just 1W to operate, but will handle up to 2000W PEP, making it suitable for everything from QRP to full legal limit. The TW-1 is accurate to ± 5% of reading across the entire power range and resolution is 1W or 1% of reading (whichever is higher). The microprocessor controlled TW-1 can easily be upgraded in the field with a simple chip exchange. It requires 11-15VDC at 200mA maximum (power supply not included) but consumes minimal current when not speaking. Suitable for mobile use, simply install it in a convenient location near your operating position and provide 12VDC through a fused line (fuse not included, LDG recommends a 2 amp fast-blow fuse). SWR Tone mode is especially useful for tuning a "screwdriver" antenna while watching the road. (LDG strongly recommends that you pull over to a complete stop before adjusting your antenna) The November 2005 issue of QST Magazine features an exhaustive review of the TW-1 starting on page 77. Additional Features and Specifications: -Frequency Range 1.8-54.0MHz -Power rating: 0-2000W PEP, Auto-Ranging -Speech: Speaks Forward and Reverse power in watts, as well as SWR -Languages: English, Spanish, German -Continuous tone for making amplifier or tuner adjustments -Accuracy: ± 5% of reading across entire HF range (± 10% on 6M) -Power requirements: 11-15VDC at 200 mA Max (user supplies power source) -2x UHF female SO239 Connectors -2.5mm x 5.5mm Center Positive DC Power Jack - DC Power cable included!
