Review on 📻 Zerone DIY Manual Antenna Tuner Kit for HAM Radio QRP - Enhance Your Transmitting Capabilities! by Bobby Posner

First, as another reviewer pointed out, make sure you search the internet for instructions and videos of others putting this together. Pay attention to the hole size for the two variable capacitors. The drilling template has TOO BIG holes, making the box unusable. Ask me how I know that. ;) Also the schematic and even the pictures don't make it clear that each variable capacitor has two sections - you want to connect the two outer pins together so the sections are in parallel. In addition, the tips must be cleaned to a shine, otherwise the solder will not flow onto them. Finally, the PCB etc is really just for the transmitter's SWR mismatch indicator. If you're just using this for the receiver then you don't need to build the board at all, just the "T" capacitor/inductor filter. I ended up ordering another one for two reasons: first, the issues with the drill holes, and second, because the 50/51 ohm resistors would be handy for the antenna analyzer I'm building.
