there's a squelch problem on uhf not shutting off fast enough. it makes listening to local police and fire not very good. my mla30+ seems to work fine on am and sw.
Apart from single(autool dm303) vs this dual channel , what are your thought comparing this to autool dm 303 ?
They are very very different types of equipment. Oil and water. The DM303 is designed physically for the harsh environment of the automotive applications and features functions and accessories that are only really relevant to auto diagnostics. The FNIRSI is far from rugged and has specifications better suited for the electronics and electronics repair technician and students. If you are in the automotive industry go for the DM303. If you are interested in electronics, the FNIRSI is the better of the two.
Thx for your info and review 👍. Only thing that stop me from getting the dm303 is the single channel oscilloscope, wish it has 2
@ElectroBananasYT how do they compare to owon hds272s instead ? What are your thoughts?
Looks interesting! I'm more of a beginner and I currently have a Kaiweets ST600x, which works OK, I often use it for testing voltages and battery and one thing I've noticed is if the voltage is very low, the multimeter has a hard time measuring it and will often incorrectly output 0v, which can't be true since I'm able to recharge the battery. If the voltage was truly at 0v it would not be able to be charged again. The only other meter I have is a DT-830B which is complete garbage and completely inaccurate. I have used Fnirsi products before, I have the FNB48P USB meter and that works great, it is far better than my Keweisi one, it is very useful. Would you still recommend the DMT-99 or would you say there's a better meter in this price range? (£25-35)? Thanks!
Thanks for watching and your detailed comment. If this is going to be your primary and general purpose multimeter, then I would go for something more conventional. The market is crowded at this price point, but in my opinion, it would be safe to go for the best Uni-T meter that you can afford. The Uni-T UT139 series looks good to me. Amazon also have a deal on the UT61B+ at the moment if you can get one (I have a UT61 series meter and think it is excellent). However if you want features like the graphical interface and USB charging then the FNIRSI is accurate and okay (and fun). All in all, the UNI-T is the way to go if it is your primary meter and you want good battery life, dependability, good build quality and will last the test of time. Get the best you can afford. The FNIRSI is the fun girlfriend/boyfriend and a UNI T is the dependable Wife/Husband. Hope that helps!
What about link to first part in description?))
Sorry, can you clarify?
Thanks for this video. What I notice is the description on the Silicon chip for adjusting soft muting. We have been trying to determine to what extent Hanrongda has sought to reduce soft muting. Eliminating it altogether would be preferable.
Thanks for watching and for your comment. As I discovered while making this video, the radio IC used for the shortwave band is the well-regarded Si4735. This chip is also used in several other popular low-cost portable radios, including the ATS20+ and the XHData D808. Therefore, there should be no reason why this IC can't be programmed to apply soft muting in the same way as those other radios, which, in my opinion, is quite acceptable.
Great video 👍..very detail n pros & cons. Considering between this 2c23T & the ZT703s.. Quite amazing boot up speed👍 For my use 2C23T fit me well at 10Mhz hopefully their firmware could fix most of the cons u mentioned. ❤thanks for making this video
Hello Jim, thanks for your kind comments! It is a handy jack of all trades and has been quite useful. As long as you are aware of its limitations I think it is great value for money. Recommend getting a zip up carry pouch for it. All the best!
@@ElectroBananasYT thanks, I had one Fnirsi 1014D bot sometime ago at home bench work, don’t want to bring it to field work, most of the time I don’t really need a scope but at times I wish I had one with me always when troubleshooting signals where meter just can’t SEE. Ordering now. Keep up yr good work. ❤️subscribed to yr channel.
Thank you! I think you will like it
Knob ! Good solution but I think cutting an IF trimming tool could be an option.. It is a shame that manufactures forget the interface to the 300 lb gorilla as AVE would say. Spending a little more time and money on a quality knob makes for a more satisfying experience. Cracked screen, looks like that is Polystyrene , the Fluke would be Polycarbonate which is more expensive but resistant to impact.
Thanks for your comment 😊. Using an IF trimmer tool is a great idea 💡. Fortunately FNIRSI send me a replacement plastic screen 😊
the internals aren't so well done. not at all reassuring. looks like it's just waiting to break.
I think the switches, small case screws and the wiring of the loop/rod antennas are the key negative points for me. Other items were okay. Thanks for the comment
Great to watch an expert who knows what they are doing. I have always been interested but only now have the time.
Thanks for your comment 😊. Glad the video was useful to you and that you now have more time!
Great video mate! I plan to re-watch it again...I did like the 320, and now I think I like this radio even better! I'm nowhere as skilled a tech as you, but I like to watch videos like this. I like the twin ferrite bar antennas. Makes the external antenna inputs look less gimmicky IMHO. Also a better speaker. 2 displays are also a plus. I don't need a flashlight. Some people will disagree. I wonder how long the included batteries last with 2 displays? I may soon find out! Thanks again...keep up the great work...😎
Thanks for the compliments! With regard to the Battery life, I think it would depend on how long they are configured to stay on. The timeout can be set in the setup menu. I may test the current consumption and report back. Thanks for watching!

Thank you 🙏
Ver nice Review .
Thank you! I see you have an awesome channel, subscribed straight away :-)
I tested a couple of units of this model FNIRSI DSO-TC3. I was more interested in the values of the parameters than the functions. All of them presented a big problem with the measure of the volts. I made a simple volt divisor and tested it with two different connections: a Voltmeter and an Oscilloscope. In both cases, the low impedance of the device influences the measure, and the voltage is wrong. When measuring with a DSO-TC3 Voltmeter, the result is the same as measuring with a proper voltmeter with a 2K Ohms resistance in parallel. When measuring with a DSO-TC3 oscilloscope, the result is the same as measuring with a proper voltmeter with a 1M Ohms resistance in parallel. They don't have any software compensation and display the wrong measure. See the attached file for the results vs. the theory. I contacted FNIRSI at the beginning of May 2024 (via email and WhatsApp). The aftersales department knows nothing about the equipment's functioning or electronics in general (they didn't know what a voltage divisor is, even after I sent the drawings). They tried to ignore the situation, and they asked me to pay attention to their website in the future in case they make a firmware update. Nothing happened until today, 17 Jun 2024. Previously, I sent the same complaints to the internet shop I purchased (in Taobao, China), and they told me the issue was a one-device issue and changed it for me. After verifying similar output, I found this is a design problem, and the manufacturer is trying to ignore it. Note that their specification already announced an input resistance of 1MOhms. What is surprising is the value when using the Voltmeter and the fact they have no correction for the displayed value. (I am using the most updated firmware version until June 2024.) On the other hand, if you want to use the signal generator simultaneously with the Oscilloscope, it will deliver a standard pulse wave of 10,000 Hz, three v, without possible modifications. I am talking from memory; I may get the frequency wrong.

Skipped the most important part... Battery replacement ... how ? It seems the other brands have the battery permanently in there. Was this different ?
Hello. The battery in this model is just a regular 18650. Just as easy to replace as an AA battery. You can see it in the video at the 06:29 mark.
@@ElectroBananasYT OK, cool . I actually just saw that doing my own research going to the Raddy site. I almost impulse bought the other brands which have the battery not changeable. These little things make a difference. Convenience and ease of use are the main selling point for me . Thanks !
Это кубик магнита чтоб вешать радио на холодильник. У меня есть такой магнит в фонаре. Удобно
Хорошая идея, однако этот кубик не магнитный. Я думаю, это просто груз, чтобы предотвратить дрожание радио при громком звуке.
Is there xy mode ?
Hello. No XY mode
@@ElectroBananasYT thanks
I just received my Raddy RF320 radio. Being VERY new to SWL Al the buttons are as foreign as the one who wrote the instructions. When a foreigner tries to write an English text they write the meanings and descriptions in the manner that their home speech directs them. They do not know and understand the nuances of the English language. An American who speaks the manufacturers language should write the manuals. Particularly in instances such as this, where the product is not designed for the experienced SW Listener/operator who knows about band designations and all the symbols on these radios. It took me over an hour to figure out how to set my clock on the Raddy. It is fun when learning is not a brain swelling process. Tedium is not my favorite cuppa tea. Eventually I will figure this bugger out.
Welcome to SWL! Hope you are having fun on your learning journey! Thanks for watching 😊
Thank you for your info about how to calibration !!
You are most welcome, thanks for the comment.
@@ElectroBananasYT I cannot get a perfect looking square wave as you have in 54:53. Wondering if this is a scope issue or a probe issue? I have 2 of these (thinking one was bad) all 4 probes the same. I cannot adjust the pot enough to make it square. Also have used the generator from my pico and same result.
Hello, do you have the probes switch to x10 (the little switch on the probe body or the probe plug housing)
I'm very disappointed with one feature of this tester and that is the Component Tester, I have a bunch of old Germanium transistors and this instrument doesn't report them as transistors but either as two diodes or two resistors, my long standing Multi-function Tester TC1, correctly identifies them as functioning PNP transistors.
Hello Derek, thanks for sharing that information. That is a surprise. I also have a TC1, I will try it with some OC71s that I have and see if I get the same results. What version of firmware do you have?
Excellent work, indeed. Many thanks for the detailed explanations. Oh, and I don't have a dodgy knob, yet....haha... ;-) PS...i can't find your DIY mag-loop antenna video....did you make it yet, or am i missing it? Thanks.
Thanks for the compliment and glad to hear that you are not having the same kind of knob issues! The antenna video is in the queue. Will release it as soon as I can!! Thanks for watching 😊
@@ElectroBananasYT I look forward to it. Many thanks for the reply.
Tu que coño haces alli?
For me the range scale bar is always showing zero:(( Althought the measurements are succesful. Any solution ideas?
I think this was an issue with earlier versions of firmware, before you upgrade, please refer to my reply to the comment from wogalwogal. Thanks for watching
@@ElectroBananasYT a firmware update did it!
Very happy for you 😊👍
I love my Fnirsi HS-02A. Iron + 1 tip is like $30 USD. I got the package with the iron and 6 tips for around $65 USD.
Thanks, but I purchased this Oscilloscope with 300AED then after one week I sold it with only 100AED because the battery drains very quickly in around 3 minutes, and the scan is very slow !!
Hello, thanks for sharing this information. The battery like on mine was not that bad. Yes this scopemeter has a lot of limitations.
Looks identical to the FNIRSI HS-01. I have the FNIRSI version and it's great
Yes I think they probably come out of the same factory. Agree, I find it works much better than expected.
I have the Kaiweets iron - I love it!! amazing fast to heat up. It has replaced my bench iron :)
Does anyone know if this would this be useful in repairing old transistor radios and modern laptops?I'm just a hobbyist who wants to try out a cheap scope to see if it helps.Thanks
Hello, yes I think it would be a good fit for a hobbyist in these situations.
@@ElectroBananasYT Thanks for that🙂
@@taxineil1 Most welcome
I agree that it would be a good fit, but if you don't know what you need it for you definitely shouldn't buy it.
Is it possible to change the temp units from C to F?
Hello, yes. This can be changed from Menu->System Settings
@@ElectroBananasYT Thank you, I didn't scroll down far enough.
They put a weight in it to make it heavier so it doesn't feel so cheap.
I thought that too. But I think the real reason is to stop it vibrating all over the place. The bass is quite powerful and without extra weight it goes exploring! 😅
There are warnings about keeping battery level high for accuracy especially using scope.Kunkune UK have an offer on at £59 at the moment,if you are a new user,sign up for an extra 20% discount,just got mine for £47 and can be found even cheaper from time to time..
I know a lot about the A320, if anyone has specific questions, they can ask me.
Brilliant
Thank you. It was fun making that video. Thanks for watching 😊
Someone knows if is posible to use XY funtion conected to a computer? USB port is isolated? Thanks in Advance.
Hello, the USB port is isolated from the Multimeter section, but not the oscilloscope.
The XY function cannot be used from a Computer.
Dear sir, I would like to use FNIRSI 2C23T for component test , but i don't understand , please help me thank you very much
Hello, that is a big topic. Suggest you search for ‘testing components with multimeter’ in UA-cam
Amazing video, it helped me a lot, changing the fuse
Hello Jaime, really glad the video was helpful to you. Thanks for watching 😊
Just now I got this 2C23T but one thing I found: the volt value that write on oscilloscope screen less than input but the drawing is correct , input is 5.000 V and the multimeter mode is correct and drawing wave on oscilloscope is correct but the value write on oscilloscope is 4.800 is there a way to calibration ?
Hello, there is a secret calibration function (it is in my video at the end), but it is only intended for use by FNIRSI during factory calibration and there are no instructions on how to use it - so don’t!!! You might uncalibrate your device!! The multimeter does provide slightly different reading sometimes, especially with ac / fluctuating voltages as the multimeter attempts to give RMS values. Were you measuring DC?
What about battery life time work?
Hello, it should last 6 to 7 hours. Refer to the current consumption test in my hardware review of 2c23t at the 38:30 mark. ua-cam.com/video/L8-KsOObSY0/v-deo.htmlsi=8_FU_l1tizvvcI4v
Your channel is pure gold. Hope it keeps growing. I look forward to seeing more of your projects. It would also be fantastic if you could provide a electrician/electronics technician device benchmark table and a reliability/durability rating. I would definitely trust and rely on any information you share in those areas.
Thank you very much for your comment Daniel. Great to hear that you found the video useful. Interesting point about reliability/durability ratings. Let me think on it :)
@@ElectroBananasYT thank you again for your content and hard work
Very good intel and excellent video
Thank you, glad you found the video useful.
Hi, is the Oscilloscope slow charging? And why does the battery drain even I'm not using it or even I turn it off by pressing the power button?
Hello, that is strange. Mine holds charge well when the power is off. The only time I lost power was when I was carrying it in a bag and the power button was accidentally pressed (it is not recessed or protected from accidental pressing). It only uses 5V charging and can’t charge at higher voltages. Sorry to hear of your troubles. Perhaps get in contact with FNIRSI, they are quite helpful.
já cheguei dando uma voadora no like, você conseguiu me convenser a comprar este ráido, parabéns pelo excelente trabalho, que DEUS continue lhe abençoando todos os dias.
Muito obrigado pelo seu comentário gentil. Fico muito feliz que você achou o vídeo útil. Você viu meu outro vídeo sobre a modificação para adicionar uma entrada de antena? Espero que você aproveite seu novo rádio 😊

Certo, ótimo. Eu planejo fazer um vídeo mostrando como melhorar a recepção de ondas curtas usando componentes reciclados simples e sem ferramentas especiais ou solda. Só preciso encontrar tempo...
@@ElectroBananasYT show de bola
2C23T is cheaper and more reliable, what do you think? ✌️🇨🇱
Hello Cristian. For a general purpose portable scope meter, I totally agree with you. I would choose the 2C23T and save some money.
Can the function generator output voltage be adjusted down to the milli-volt range like 0.0025 v and 1kh frequency?
Hello, output voltage can only be changed in 0.1V steps. So the lowest is 0.1V.
Incredible video that you've done here. And thank you much. It really caught my eye when I recognized it as the same radio that I purchased a couple months ago. I must say that I did not open my radio but I am very impressed with how well I like the radio. It is packed with some amazing features for no more than its size. Soon I'm going to build a better shortwave antenna externally from my home. I will probably just use an alligator clip to connect to the telescopic antenna and then I will probably draw the ground off of one of the auxiliary jacks . Again thank you for your video and I will share it. I will also endorsed this radio as being an excellent choice for a prepper radio and for its value. You did a good job in showing that this radio is well built. Again thank you and I will be watching more of your videos.
Thank you very much for the kind comment, glad you found the video useful. Yes the radio is great fun and sounds great for the size of the enclosure. I am making a video on how to make a DIY loop antenna also. Hope to release in the next couple of weeks.
@@ElectroBananasYT awesome and I'll be looking forward to that
Very well done. Thankyou.RON Z. WA3090SWL
Thank you Ronald
I got mine yesterday. So far it's looking to be perfect for hobby electronics use. As far as using with high voltage/current, I wouldn't use any random named Chinese meters for that. That's what my Fluke is for.
Thanks for watching. Well as long as you are aware of the limitations of this device! I always revert to my trusty fluke!
This oscilloscope can't display random signals on high frequencies. It's a scam. Test it with FM signals. See the Kerry Wong's video.
Thanks for your comment. Yes you are right, I am making another video on the performance and the oscilloscope has a number of issues. I would not trust it.
Why didn't FNIRSI catch the big mistake on the front, it says "FUNCATION" Wow!
I know, it is a very big boo boo! Terrible PR for them and makes you question their QA processes. I also don’t like the use of the word ‘Gear’ instead of ‘Mode’ when selecting the mode of their multimeter function.
They have terrible QA and even worst support. They shall put more effort to polish they existing products instead release new one. Saying that, despite all issues with F gear, I did all my hobby works I needed with this gear.
nice
Thank you for watching
素晴らしい 解説をありがとう そしてcasioを使っていて日本人として、とてもうれしいです (≧∀≦)

Hi, I’m considering purchasing one of these, but was wondering if the one you have still works to see how well it lasts. Could you give an update on that?
Hello, my original unit is working well and I enjoy using it. I accidentally cracked the plastic screen, however FNIRSI sent me a replacement. Other than that all good. I also bought a protective pouch to carry it around in.
Ok, I’ll probably make the purchase. Appreciate your feedback👍🏻
