Hello Fred mate. I'm Daniel 26CT196 now known as (26PAT196) MR PRESIDENT. We had a qso a long time ago. (Roughly 3 years) I was a massive fan of your channel. I was only 13 years old. (16 now) I'd just like to take a moment to thank you for the qso you had with me that day. It taught me alot and was extremely Kool! Having a chat with fred in the shed! I have ended up with a room full of radios. Now 3 years into the hobby. My mums house is home to all different bits of wire and spare parts. I Doubt I would have carried on the hobby without your youtube videos keeping it alive. Massive respect from MR President, Fred Keep doing the videos👏👏

Great review, thanks. I've bought the ATU-130 max variant to feel more comfortable pushing out the 100 watts of my FT-891 into it. I'm quite happy with it. This variant has 3 buttons: bypass, tune/reset and auto for easier control but the rest including the firmware and display are almost the same. The only difference is that there's a spot on the screen that shows "_" (underscore) while in bypass mode and "." (dot) when in auto tuning mode.

Be nice to see a lenth of wire connected up to see how this tuner performs Fred

Frid in the shed I learn lot from you about bying cb radios and antennas for cb radios and power supplys for cb radios my friend

Hi Fred! Good review! I had two of these, first one was DOA, the second one ( replacement) had variable results everytime. I then switched over to a good old fashioned mechanical Tuner, Comet CAT-300 and have never looked back. I believe, I just was unlucky, a good friend of mine has exactly that automatic tuner and is very happy with it!
These gadgets are being sold in such huge numbers, there always can be a "unlucky pick". I since then just go by the rule: pay an adequate price and get good quality the first time round! But it is true, when this tuner works, it is a steal!

The small button on the back will turn on auto tune. You will see a small dot pop up on the display. It switches between manual and auto tune.

I remember the power supply in a toolbox you made.

A rechargeable powerbank using 18650 lithium cells next please fred!!

It'd run that ATU

[Greg-etdp]

Frid in the shed your new ATU-100 cheap antenna tuner is awesome my friend

[alanslade]

Thanks Fred for that price you can't go wrong. Thanks again Alan from LUTON 💯👍

[billmorrison]

Definitely worth thinking about for portable and mobile uses, the price is right.
Great review Fred.

Frid in the shed your YouTube videos are awesome my friend

Fred NICE review of this useful little unit. As aways I think you have to be wary of the BUILD quality of the pe-built units and maybe best to get a kit and build it yourself. The reason it needs a good 5 watts to tune is because of the RELAYS inside, similar concept of the relays inside a LINEAR AMP. It does look like a pretty useful unit IF you get a good one. You CAN improve this unit by replacing the DIODES inside for some general purpose Horinktor 1N5711 Schottky Barrier Diodes. So regardless of if you buy the pre-built version or the KIT, it would be well worth fitting the Schottky diodes. 73's Fred.

I suppose the switch on the back is for switching between auto and manual tuning. On the pictures at Bangood it says A/M so I guess it the letter printer had a bad day 😄

Frid in the shed iam thinking about getting my Grms license

[richardmillican]

Id be inclined to regularly check the swr reports from that ATU initially. Just to play safe. Its probably good, but sometimes the quality assurances from china can be overstated!!

I wonder if you tested say, 3, one after another, if theyd all report the same results?

[DonzLockz]

Great bang for buck Fred. This could work nicely with the Hermes Lite2. :)

[bazfitz]

Hi Fred....Quick newbie question.Im building a Doublet Antenna in the loft for listening only.Apparantly i need an ATU....Would something like this work or does the unit need to see a Transmit signal like when you key up to calibrate?Sorry for the daft question...Barry

[michaelaris]

Can you run an amplifier in line with this ??

[CBRadioWayBack-]

If you need to use an ATU on CB you shouldn't be on CB..
simple..

[stuman]

That certainly looks quite good considering the price. Bought a new Baofeng from Banggood after watching one of your recent videos and it arrived within a week. So quite pleasedv with them as a seller.
