1.8‑50MHz 200W Shortwave Auto Antenna Tuner, 10‑15VDC Automatic Antenna Tuner Metal Housing PIC Chip LED Display Micro Antenna Tuner

My first unit would not power up. I returned it and Amazon sent another right out. I’m very happy to say that the second unit powered up right away. Put in on my base radio and antenna at 50W. I set the tuner on AUTO and pressed the PTT. My radio sent out a 10W tune signal and the little tuner went to work. Since it was the first run I was surprised to see it tune much faster than my AT-600Pro II. Selected a second frequency on a different band and again it worked quickly and fairly quietly.The display gives my power output, the antenna output, the SWR, and the Efficiency while transmitting.When idle the display gives the Capacitance and Inductance values it is using to match my antenna.When transmitting in Bypass mode it shows how bad my SWR and Eff are without the tuner. These readings are a very close match my antenna analyzer.To the person asking a question before I had a working unit, Yes it will tune at 3W, it even tuned at 1.5W on a new band. Great tuner for my POTA Go-Box that I’m building. [...]
