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

This item came with no instructions, diagrams or any assembly help, I should have read the reviews. Not worth the money or time, DO NOT BUY.

problem. I had to ask the seller for a diagram which he made via email. excellent . It is difficult to determine the number of turns on the toroid, etc. But the information sent was very useful. Parts lists and wiring diagrams should always be included with the electronics package.

I am an experienced radio amateur, kit maker and electrical engineer and this "kit" was a huge disappointment. You have to drill your own holes. Not a big deal since I have a drill press, but still out of character for the kit. No instructions. Since you have to wind your own toroid, this is a big problem if you haven't already done so.

In addition, the…
