It's loud enough as it is.
All design, no substance. The allround hand soldering is appaling.
What’s the minimum capacitance that we can measure?
Very good video. I learned much by watching. When I have to fix a piece of my equipment in the future, I will think of this video.
Thanks for the kind comment. Glad you found it useful.
What a nonsese, if the weight of a multimeter decides if it is good. You don't understand antyhing about build quality. But who pays your bread, decides.
Thank you very much taking the time to comment. I measured the weight as a point of interest as the meter is incredibly light. The weight, of course, is not a consideration in the pros and cons at the end of the video. Later in the video the unit is dismantled and build quality reviewed. Wishing you well.
the radio for steven seagul
😅 You could be right there!!!
Thanks for the overview and teardown & hardware review
You are most welcome 🙏
do the scope in put jacks share a common ground .This is very important to know if one cannel is monitoring a module or an injector that is pulled to neg/ground to operate at the same time using the second channel to monitor a device that has a constant neg/ground . Switching of the controlled neg/ground would be defeated .
The multimeter inputs are isolated from everything else. However the scope inputs, signal generator output and USB share a common ground.
@@ElectroBananasYT thanks. that's very dangerous if a person does not know this before they start to do testing
Potentially yes, I agree. I do cover that in my video.
Citizens Band is mess on my TR-113 and fails to work properly. Scanning for signals it just blows right by those, if I jog the tune button to say 27.1250 Mhz or just manualy enter it then it will pick up a transmission but only with squeltch at zero. It worked fine on Citizens Band for about 5 days then it started not working correctly. Not happy with this, notbwell made.
Hi, sorry to hear you are having issues. Did you get in touch with Retekess? Strange how it used to work. Hope you get it resolved.
THIS is what I call a diligent and thoroughly review. Thanks!
Thank you very much for your kind comment. Really appreciate it and glad the video was informative for you.
I have a RF320 that overloads on strong MW stations any suggestions on how to fix it?
Hello, sorry I don’t have solution for that off the top of my head. I don’t see the issue as we don’t have MW broadcasts where I live.
Yes but did Raddy send you the radio knowing you were going to take it apart? I won't be buying one until they ship it out without muting and it doesn't sound like it does well on MW either with lots of spurious sounds.
Well they would have surely seen that I like to tear things down in my previous videos!
Hi - great teardown and analysis. I've had this (Raddy RF320) for a couple weeks now. I'm mostly happy with the AM (MW), FM and shortwave performance. On VHF, I'm getting some local FM broadcast breaking through at 1/3 the nominal freq (eg a station at 96.3 MHz showing up on VHF at around 33 MHz approx), and also at 2x the nominal (eg the above also showing up at 192 or so MHz). Otherwise, narrowband VHF reception is ok but not stellar. And finally, my RF320 is deaf on the airbands, while my Quansheng UV-K5 brings in several of them with no problem. How was your reception of the air band?
Hello, thanks for your comment, much appreciated. Yes I found the same issues on VHF.
Ya hay un nuevo sofware en pagina que corrige los errores
Thank you for sharing
I saw few advertisements and on few of them they stating that has also infra temperature sensor that showing heat on the main display. Is that true?
It have a simple internal temperature sensor, but it not accurate.
Ok no infra red?
Correct, no infrared sensor.
Thanks for helping make my Raddy R-919 a little more understandable, especially that top jack. Good to see inside the little beast without violating my warranty…😂! 73! Have a great day!
Thanks for the comment! Glad that you found the video useful. 73
Thanks for an awesome informative down to the point video. Also very ASMR and relaxing I might add. Im ready to hit the purchase now button, but im curious as to weather or not the soft muting has been addressed on the new outgoing models? Im not going to attempt to upgrade the FW myself. Me personally id like to see the muting gone all together, I enjoy surfing the bands by ear. Thanks again, 73 KD0OOP
Thanks for the feedback, really appreciated ☺️. Yes the latest models are shipped with the latest firmware that makes the muting issue a little better. You may want to buy direct from Raddy to ensure you are not buying old stock that may not be updated. Have fun with it! 73
It would be interesting if there is a review and teardown on the Xiegu X6200. Tks.
I would like to review one myself 😅
Can it run Doom?
It could probably run a cut down version with a simple WAD 😅
Hello, my Raddy RF-919 which I have owned for a month has developed a fault, I had the main screen backlight set to permanently on for a while, it began to flash for a while and now does not work on the default green setting, it does however work when set to one of the other 6 colours, I was wondering if the backlight uses small smd LED's for each coulour, or if it is some kind of electro luminescent backlight panel. I.E. is it fixable?
Hello Paul, that sounds frustrating! Is it not under warranty? I did not open the display backlight system, however I expect it will be LEDs. May just be an issue with a back connection or solder joint on the green LED chain. So probably fixable.
@@ElectroBananasYT thanks for your response.
Hi I bought this to do a relative compression test on my subaru via a waveform. but cant seem to make the amp probe plugged into the multimeter ports work. is this just not possible with this unit? do i have to send it back and get something else?
Hello Keith. Very sorry - not familiar with the system that you are trying to plug it into. Hope you manage to get your question answered
@@ElectroBananasYT thanks for the reply!
Just use the scope to measure battery voltage fluctuations, which will give you a cylinder by cylinder voltage drop, and compare them.
That is an interesting technique. Thanks for sharing the idea ☺️
@@johnnodge4327 nah man the problem was hooking the probe to the multimeter, I ended up having to get a adapter that would make the oscilloscope connections to multimeter connections.
I'm sending mine back. Despite the audio quality and frequency range, it's not well designed or well made.
Thats some poor quality for a 250-300 dollar radio!
Thanks for your comment. Yes the switches and interconnection techniques look surprisingly cheap. I think a lot of the cost is the labour required to put this thing together- there is a lot of hand assembly required.
Mine went crazy after measuring the 6 amp current in an rf amplifier. Frnsi offered zero support
Surprised that happened! Could there have been some RF on your power supply rails?
It would have been nice for the air band side of this radio to have placed a copper coil. So that it does not receive AM broadcast radio stations. The copper strand could have been separated for the air band stations to come in properly .
Hi, thanks for your comment. By copper coil I presume you mean shielding? Where I live we don’t have any AM stations, so did not experience any issues with Airband.
You can get the V1.707 firmware, it mostly fixes the muting issue. The issue with bricking is when people don’t properly format the memory card as fat32. 706 was the one people had issues with, not 707. It the same radio as the ZHIWHIS ZWS-c919. They will supply the firmware when the radio is bought through them. Raddy I think got burned by people not doing the upgrade correctly and it seems they won’t provide the firmware, even though the new version is out. Same chips, same radio. Your risk as they say. I had no issues. 73
Hello there, thanks for the comment. Yes, I am now on 707. These different branded versions are all manufactured by HanRongDa, so all essentially the same radio. 73
I had two radios bricked by trying to upgrade and my cards were formatted correctly as FAT32. I followed their instructions to the letter, but they still bricked. I was reviewing the radio and made RADDY aware of the issue.
@@ClareBarrington Thanks for sharing. Did Raddy eventually resolve your issue?
@@ElectroBananasYT Yes they did - I have had good customer service from them. Cheers!
Top notch tear down.Thanks!
Thank you very much!
Guarantees We Don’t Need No Guarantees😂😂😂
Ha ha! I can’t help it, I just need to find out what is inside!
Nacho cheese fingers.. someone here likes to eat Cheetos cheese puffs!!!
😂😂😂😂 I do like Cheetos Cheese Puffs, but that is not the culprit. It was from helping the wife cook. She never told me that she put turmeric in the marinade!
too bad it doesn't xy mode.
Agreed. The manual mentions XY mode too. I think it may have been in the prototype and they removed it, perhaps it was not working satisfactorily.
This Guy is a genius. As far as the external ferrite rod antenna goes, I see no disenable improvement on medium wave, but a massive difference for long wave, which was very poor before. Radio 4 on 198khz was unbelievably weak here in the west mids.
Thank you! ☺️ unfortunately we don’t have any MW or LW stations where I live, so could not test it. Thanks for sharing 😊
Hello sir. Luv the vid. A great idea. I currently own 130 receivers but use the rf 320 often.No problem with the encoder so far.thanks RON Z. WA3090SWL.
Hi Ron. Wow, 130 Receivers!!! Amazing. I use the 320 a lot too. Thanks for the comment ☺️
exellent description.....!!
Thank you for your kind comment.
There Goes The Warranty Journey To The Bottom Of The Rig
Ha ha, well, what to do? I can’t resist opening these things up!
Been a somewhat a communications radio to me was to much bass so i took out the base reflex at the back and now you can here clearer speach on SW/AIR/HAM/ETC., i know you have heavy bass FM if i want to listern to FM i use my HanRongDa HRD-A320 better still home stereo amp.
That is an interesting idea, Thanks for sharing. I guess it comes down to personal choice. I actually quite like to hear the low frequency sounds. Happy listening!
Isn't there a EQ choice for "voice"?
Great video. Could you do a complete teardown on the new Tecsun S 2200x. I am torn between getting the Raddy RF-919 and the Tecsun S 2200x. I really like the extended specifications of the Raddy but I am concerned about its build quality and durability. The Tecsun seems to be a higher build quality but its specifications are limited compared to the Raddy....Life's full of tradeoffs...Thanks
Thank you for your comment. I would also love to do a similar review of the S 2200x. Unfortunately I do not have access to one at the moment. I understand your dilemma on choosing a radio. No single radio seems perfect! In the end, I think you need to consider what features you will really use. Thanks for watching 😊
Would like to see a similar video with one of the clone RF919. Curious if there is any difference.
Hi, thanks for the comment. I don’t think they are really clones (one company attempting to copy the design of another). I suspect that they are all manufactured by HanRongDa (HRD) in Shenzhen ( SHENZHEN HANRONGDA ELECTRONIC CO). Resellers like Raddy order the radios from HanRongDa to their respective branding requirements (colour, brand name, logo, Bluetooth ID etc). So they will be identical inside. One exception is Retekess (They brand the radio with model number TR113) who request HanRongDa to fit a different battery type (3600mAh polymer instead of the usual 2x2500mAh Li-Ion 18650s) to meet the requirements of the countries that they sell / operate in. Thanks for watching
Having seen in side it and how its built it looks like a £50 toy radio.
Some parts and construction techniques are low cost, agreed. Especially the switches and the decision to solder wires directly on to the tracks of the PCBs rather than use connectors. That was a surprise. I think a lot of cost comes from the amount of manual labour needed to put this together - the whole rod antenna assembly and antenna tuner must take considerable time to construct. Having said all that, I think the PCB assembly and rotary encoders, displays and speaker are all good. Thanks for the comment and for watching.
I bought one due to meter functions. Always needed a scope for domestic repairs. I think this purpose is OK. For lab uses, of course I would looking for top notch equipment.
Yes I feel the same way. Handy general purpose device, but not for professional use. Thanks for the comment and for watching
Excellent review. Insightful, thorough, substantive.
Thank you very much for your kind comment Robert 🙏
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.
Hello John, thanks for your comment. Not heard of the squelch issue before. If you have a short clip of the issue, feel free to email it to me, would be most interested to see what you are experiencing. Thanks for watching
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?
The HDS272S is an amazing handheld for the money. Much better than the FNIRSI in so many ways. It is in a different class, but so is the price. I don’t own a HDS272S, but would love to…
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?
@@ElectroBananasYT Video description starts: "The second part of my review of the FNIRSI 2C23T..." Second part?? So...was there a first part? EDIT: yes: ruclips.net/video/L8-KsOObSY0/видео.html
Thanks for raising this. I have updated the descriptions to include the links for these videos 🙏
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
@@ElectroBananasYTjust got the 2C23T yesterday. Yeah, I kinda like it. Too bad seems Fnirsi had taken down the firmware for 2C23T. Mine is ver:2.1.0 is this the latest? Thanks for your sharing ❤like to watch yr video.
Hello there, I’m glad you received your unit 😊 I think it must be the latest if you have just received your device. Have you checked FNIRSI’s Website? I am still on V2.0.2.
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!
@@ElectroBananasYT I always take pictures before I take something apart, but I suppose you can always refer to your video if some of the labeling comes off.
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!
