Dave has added a nice wrinkle &#8211; the SWR indicator employs TWO leds, not the normally seen single red LED. A green one indicates output power with a red one indicating reflected power. The beauty of this arrangement is that the operator sees the output power peaking as the SWR goes down, just like a power meter with dual meters &#8211; very intuitive. This makes tuning easier and leaves no doubt that it&#8217;s tuned for maximum power output. For a high SWR the red LED is at full brightness and the green LED is off. At 2:1 both are at equal brilliance. At 1:1 the green is full on and the red is off. The small size is perfect for portable operations. Add this dandy little tuner to your portable ops go bag, or use it at home. It&#8217;s equally at home on a picnic table, in a tent or camper, as well as on the operating desk in your shack.<\/p>\n<p><strong>Specifications and Design Features<\/strong><\/p>\n<ul>\n<li>Wide tuning range: 80 meters thru 10 meters.
