Malahit ATU-100 EXT Antenna Tuner 1.8-50MHz atu100 by N7DDC 7x7 0.96 Inch OLED 3.2 Firmware Programmed with Housing Assembled Machine with USB Cable（No Battery） Compatible with Radio Antenna

I will update this review after I take this unit to the local state park for my POTA use. I am using this with my (tr)uSDX transceiver (that is a low-power, or, QRP, rig).First: The review about soldiering and so on - any ham radio operator ought to know how to take the power cord and put it into use with a batter pack or other power source (12v). The included 5v-to-12v "booster" is the only thing internally needed, if you don't plan on using a 12-volt supply, but only a 5-volt USB power source. I would not do that, as I plan on using solar panels and batteries.Initial power-up takes about two seconds, then comes alive after the internal self-checks. The display is easy to read, but maybe not in full sunlight out in a park. It does not draw much current, so it will probably last all day in the park, on a modest 12v battery pack. I am using a 12v assembly for AA batteries.Again, I will do a full review and a video once I get it in the field. My initial impressions are that this is a perfect ATU for amateur radio QRP use out in the field.

Works great! Connected to a 17 foot vertical with a 1:1 balun and instantly made dozens of FT 8 qso’s.

Me gusta la seriedad de cumplimiento del ebio de las compras y la calidad de los productos exelente

This ATU is really great so far, so good! There is essentially zero documentation which could be easily solved by providing a link to the info. There are some YouTubes with useful ( unfortunately incomplete) . Simple “what do the buttons do “ would be a good start.

Works fine for me, using with Hermes lite 2.

I completely read the description of this product before buying. At no point does it say this is not able to be used straight out of the box, or that you need to hire someone with experience to take it apart, solder a power cord to a circuit board, or any of that stuff. If any part of the description said this, I would not have ordered. Downright deceptive advertising which I plan to send to the Better Business Bureau. I plan to return this first thing in the morning for a full refund. DO NOT BUY! DECEPTIVE ADVERTISING! You have to take it apart, solder a chip to the circuit board before the thing can even be turned on. Shame on Amazon for even selling an item that has such a deceptive description.

Excellent tuner. Very forgiving. Impressed so far!

Good product, quick shipping
