Hi Phil,
I have excerpted a bit of the Handiham newsletter dated yesterday;
actually, they didn't date it yesterday, I did!! Info on the LGD power
meter including the LGD website with more info and a list of their retailers.
Looks like a great device; bet one will find its way to my shack!!!
Hope this helps.

The TW-1 Talking Wattmeter provides an aural spoken indication of power and
SWR using a synthesized voice. It is ideal for the vision-impaired, for those
of us in the "bi-focal set", or just for those times when you need to be
looking somewhere else. 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. It includes its own internal 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 just the
thing for peaking your amplifier while keeping a close watch on the grid
current.
You can select either long or short voice reports. 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 5 Watts to operate, but will handle up to 2000 Watts
PEP, making it suitable for everything from QRP to the largest amplifiers
in amateur
service. The TW-1 is accurate to +/- 5% of full scale across the entire
power range; this may very well be the most accurate wattmeter you own.
Resolution
is 2 Watts.
The TW-1 is microprocessor controlled, and can easily be upgraded in the
field with a simple chip exchange. It requires 11 - 15 volts DC at 200 mA
maximum,
but consumes almost no current when not speaking.
