Re: uBitx v6 with hardrock-50 HF Power Amp Kit

John Faivre

I use my uBitx V4 with a Hardrock 50. I only run FT8, so I use the WSJT PWR slider to adjust the power. 1 watt gives me around 50 w out on all bands except 20. For 20m I run about 2-2.5 watts out of the UBitx.  Running higher wattage Into the amp causes the output to up as well. For instance 3w on any band excep 20 will give you about 70w. But I do not know at what input causes distortion On the output. I stay under 60w.
