Quality control is horrible
On my second one and this one is going back. First one had no power pack and modulation meter was broken. Second one came, everything seemed ok, found the on/off switch is backwards and the frequency meter won't turn on. This company Dosy has some QC issues....

Seems to perform as it should. The frequency readout was spot on. And the swr, power and modulation meter seem to match fairly close to different other meters i have...

Made cheap although price is very high.
Good news is it dose work as intended. BAD news is panel labels are poorly screen printed and meter back ground is printed on paper. Light shines through black portion of the paper. Panel print is readable but looks pixelated. For something that cost over $360, they should have spent more than 3 cents on the meter back ground. Printed aluminum meter back grounds and decent panel decals would have made this an awesome product. Panel back ground actually looks better with the light off.
