100W HF Linear Power Amplifier for YASEU FT-817 ICOM IC-703 Elecraft KX3 QRP

I came across this item while searching for an affordable amp for my QRP SDR. This is clearly a bootleg version of the JUMA PA100. While the PA100 Gerber files are available for homebrewers to download, it’s *not* open source hardware. In fact, the JUMA site contains a warning about Chinese companies pirating and selling their designs. Support amateur radio innovation—don’t support piracy.

I did not see any mention of the required FCC certification for external RF power amplifier. Use or sale is illegal in US.

You must be kidding me over $500 for a 100w amp? Get the Elecraft amp it's about the same price and you can be sure you the value for the money instead of some back alley dingdong amp.
