Hello ElctroBananas ! I've just bought myself that radio, I'm absolutely new to using such radios, I've got a basic understanding of it, what ressources would you recommend me for this one ? I've heard you saying its documentation isn't the best... I love its retro look (I say retro as I'm in my early 20's haha!) Regards

Thanks for the extensive and friendly description, now I know how to replace the fuse (it's better not to burn it!) And how do you measure temperature with it?

Brilliant teardown, very informative. Regarding the external ferrite antenna, my guess is this is for the convenience of not having to turn the whole radio rather than performance. Sounds daft maybe but... it is convenient!

I have just ordered one. Thanks

1 whole hour of high quality high detail review/teardown, amazing job thank you 👏 just ordered one for about £69. Even though it's homegamer-grade, isn't it kinda mind-blowing that we can have such a thing, for so cheap. 10 years ago this would be a £1000 Kickstarter 😂

It seems that the isolation gap between the multimeter function and the rest off the device is way too short. That means that BNC;s and charging port should be considered dangerous to touch eaven when using it as a multimeter. This could be a major safety issue. Maybe the BNC s are resessed in a bad attempt to prevent unintentionally touching them.

Is it possible to turn the touch sound off completely on the device? Seems like no?

Congratulations for your insight. I just received this item ( fnrsi 2c23t) today, ordered by a brother in the USA, and send to me here in Nigeria. Thanks for your video and explanation. But, opening the box, I found that, the company or the manufacturer did not include the charger, only USB cable. So how do you use USB cable without a charger? That is an error.

Looks like it's been made in a shed by an amateur. Awful quality. Thanks for the Heads Up. I definitely won't be buying one of these.

Hello, mate! I don't know if you've continued testing the oscilloscope. I've bought one myself, and I'm having an issue with the screen refresh when using the single trigger. Does something similar happen with yours?

This radio and its little brother are interesting, but tbh I have no idea who should buy one.

Ever wonder which chip, when it receives the special signal sent during war, will render the unit inoperable? Because it is in there, you can be sure.

I am local Singaporean and also brought this radio. wow , impressive mod. At 31:56 u received thai/vietnam and China radio station not Singaporean Chinese radio station. nice work!

The Radio R12 or Degen R12 appeared as the same a320 without external antenna, you have also repair it

I was going to ask my wife to get me one for Christmas there 219euro on the Raddy site do you think they are worth the money i have tescuns xhdatas and the lastest qodosen and a couple of decent sonys but i like the look of these but i dont want my wife wasting her money if they are not worth it.thanks Ged .

Why did you put 60gr back?:)) it is

how about new HRD 757? is HRD A320 still better?

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.

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.

the radio for steven seagul

Thanks for the overview and teardown & hardware review

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 .

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.

THIS is what I call a diligent and thoroughly review. Thanks!

I have a RF320 that overloads on strong MW stations any suggestions on how to fix it?

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.

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?

Ya hay un nuevo sofware en pagina que corrige los errores

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?

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 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

It would be interesting if there is a review and teardown on the Xiegu X6200. Tks.

Can it run Doom?

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?

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?

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!

Mine went crazy after measuring the 6 amp current in an rf amplifier. Frnsi offered zero support

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 .

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

Top notch tear down.Thanks!

Guarantees We Don’t Need No Guarantees😂😂😂

Nacho cheese fingers.. someone here likes to eat Cheetos cheese puffs!!!

too bad it doesn't xy mode.

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.

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.

exellent description.....!!
