Here we have a new HYS TS-300 QRP HF amplifier. They are advertised as cover 80-10 but during testing I found that it also works on 160 meters with close to 200W output. I bought this directly from China thinking I would use it on my QRP rigs for a bit of extra RF when needed. However, I found that on certain bands the input SWR was a little too high for my tastes. Output varies from 100 to a little over 200W depending on band and input power. My testing was done with 2.5 and 5W from an FT-817. One thing I did find in this wonderful piece of Chinese technology is the HI/LO power switch is labeled backwards so I made a couple of little labels and corrected it on the front panel.

If my items have any known issues I will list them as I test ALL equipment to the best of my ability before selling unless otherwise stated. Most of the equipment I resell comes from hamfests. Although I do a thorough job cleaning these items up there is always the chance that the item may have come from a smoking environment. I DO NOT give refunds for smokey smell!
