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👏👏
Hi. Lovely to hear from you. Yes i rem you coming on the radio. Glad you have stuck with it. Thanks for the kind comments. Maybe time to think about HAM radio ?. Enjoy the summer of MASSIVE skip this year.
Be nice to see a lenth of wire connected up to see how this tuner performs Fred
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.
Nice one!
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
Frid in the shed your UA-cam videos are awesome my friend
Frid in the shed your new ATU-100 cheap antenna tuner is awesome my friend
Thanks and stay safe bud.
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!
Thanks Fred for that price you can't go wrong. Thanks again Alan from LUTON 💯👍
Nice little {not mega expensive} antenna tuner. I remember reading the details about the kit on Github and I believe the button is for Auto or Manual/Bypass. 👍
Thanks for the info!
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
Definitely worth thinking about for portable and mobile uses, the price is right.
Great review Fred.
Ive been running this exact tuner for about 3 months now. Paired with my anytone quad5 n2. Connected via lmr 400 to a sigma venom high gain half wave. Works wonderfully. The a/w at rear is for auto mode. Once engaged. Unless vswr is 3:1 or higher the tuner does nothing. This little unit can take a mono band antenna and work it over 2 nice vid! Cheers.
Thank you for the info. Glad it worked on your set up.
Great bang for buck Fred. This could work nicely with the Hermes Lite2. :)
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.
Thank you .
Good review Fred ... interesting little antenna matcher certainly good enough when using with the wide frequency range ..if proved to be reliable not a bad idea to have always inline so keeps a monitor on vswr ect and give an early warning of any fault.
Best wishes Mac
Frid in the shed iam thinking about getting my Grms license
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 😄
SWR drift will happen when your antenna is wet however it should not be massive change, you should check your antenna and make sure you have not covered any weep holes with tape etc...
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.
Thanks for the info. Yes its not too pricey to have a go at modding it yourself.
I "ordered" ha! I cheap Chinese charge controller for a solar system I was building on my boat back when. It didn't last at all. So anyway. My mom only gives me 5 dollars a week! :)
Hi Fred just been watching your videos, and I came across a app on the phone for the MIDLAND CB TALK, AND I'M VERY IMPRESSED WITH IT, because you can get a map on it to see were people are, and a lot more, just wondering if you new about it, I'm positive you've already heard of it but I just thought you might like to know, thanks again for your work Alan from LUTON 💯👍
Thanks Alan. No its a new one to me.
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?
I did test it and it was not far out unfortunately. Got it better now.
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
Hi. Yes this ATU requires a transmit. I would have thought that an older manual tuner might work.
Hi Fred isn’t the tuner only fooling the radio into thinking everything’s ok,surely the antenna is getting the same power as if the tuner wasn’t connected,the tuner cannot tune the antenna ?
Its just giving the radio 50 ohms. Less power will be reflected back to the radio but as you say the tuner will lose some of that.
The tuner allows the transmitter to put its full power into the system by way of a conjugate match, if the tuner wasn't in place the power tx power output would reduce to the amount of reflected power
@@CB-RADIO-UKfred the tuner will reflect any reflected power back to the antenna in phase with the forward power
it doesn't turn the antenna it matches the impedance to 50ohms between turner and radio.
How can it turn the antenna without a rota ?
Reckon that was a typo error and should have read tune not turn 😂😂
@@cbrmacit tunes the system to resonance by canceling out the reactances
If you need to use an ATU on CB you shouldn't be on CB..
simple..
