    I’m a musician and I build my own speaker cabinets. The heavier a cabinet is, the more clarity comes through the speaker when listening at higher volumes. Lighter housing allows more resonance that interferes with outgoing sound.

    Perhaps the chunky steel parts (Three of them? The cube plus two long ones beside the battery?) serve to help prevent speaker-induced vibrations of the radio case and associated audio rattling.
    Thanks for this tear-down.

    • @ElectroBananasYT
      @ElectroBananasYT  10 місяців тому +1

      Yes I was thinking that. Also, without that extra weight to push down on the rubber feet, I think the radio would move all over the place when it is turned up.

    Thanks for this tear down video and analysis. I listened to your video on my ZHiWhis using BT off my IPad. The resonance test made my unit perk up…😂!
    I bought my ZhiWhis ZWS-AF320 back in August of 2023 which is supposed to allow you to record on the radio without using the app. Unfortunately, all my SD cards are backing up my extra data or are used in my SBCs.
    Although SW is a mixed bag, FM,Aircraft and Weather band were decent. Surprisingly, the MW picks up stations I heard in years at night,especially when paired with my Trek advantage Loop antenna. The telescopic whip is really flimsy so be carful when attaching the provided extension antenna. I just wish they would have put the telescopic whip antenna that is on my ATS-120 radio.
    Well 73 and have a great day!

      Yes, the radio is pretty decent for the price, considering the other features that are packed in. One evening, I managed to receive Radio Turkey in Singapore, inside an apartment, and without an external antenna. Yes, the whip is flimsy, although I think the very thinnest part is designed to be flexible. You have a great day too!

    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?

    • @ElectroBananasYT

  • @johnlannigan9831

    This is a very interesting radio, mine arrived a couple of days back and I've had a bit of fun playing with it. One feature the instructions dont fully explain and its not detailed in the instructions is the NBFM and the range of 30MHz to 199.95MHz. Listening and comparing the results on the radio ham bands, I have found the receiver a little deaf on 6m and 2m. Broadcast FM seems lively enough. But back to the NBFM, I found listening to a reasonably nearby 6m repeater was almost impossible inside the house, I could occasionally, comparing it to the same repeater on a 6m Yaesu FT690 hear the odd words as I moved the radio around, the 690 picked up the same repeater very noisily but slightly better. I had in my junk box one of these cheap 0.1 to 2,000MHz preamps and did a quick lash up to the radio, connecting it to where the telescopic antenna was connected. The results were quite impressive, certainly very close to the same level as the Yaesu transceiver. Adding an external antenna socket wouldnt hurt, possibly a 3.5mm mono jack (switched?) I suspect though that with the level of amplification used, it wouldnt be a bad idea to have some form of low pass filtering. My next idea was to add a BFO for SSB for the ham bands, any mods I try to do in such a way that it looks as if the mod was intended to be there in the first place. A simple Colpitts oscillator that is varactor tuned will allow me to use a variable resistor with an edge knob mounted in a slot on the join of the case. Oh, and that LED light that is next to useless and very dim, that will get a better Cob fitted. Its a nice receiver that can be made much better.

    • @ElectroBananasYT
      @ElectroBananasYT  Рік тому +3

      Thanks for the informative comment John. I wonder if you could fit that preamp inside the case somewhere. There is some room around the speaker. The BFO would be interesting to see also. Have fun with it!

      That was a good features demo, teardown, performance and all things comparative to the actual specs
      if I may say and there's hardly anyone aside from yourself that gets down to some of the nitty gritty of
      some of these radio builds. I am viewing your channel content for the first time and it was well worth my
      time and I can appreciate all of your time going through the motions with good ease and clearly understood
      most of what makes up of this radio build, topology and layout. As for that block of metal that you found:
      The location of it is 1.) It is situated diagonally across from the speaker magnet for starters. 2.) It is purposely
      and firmly planted and has a specific density and mass to help dampen cabinet vibrations for perhaps two
      reasons. As with some honing in and a listening device that Bluetooth capabilities which can be an sob, such
      as a possible spying type apparatus, such as to monitor communications that take place remotely or from
      afar, such a feature can be viewed as a COMSEC bad; very bad. And so for the phone app usage as well, to boot,
      you wouldn't really know whether data packets are being transmitted back to China via WiFi; especially if once
      the app is fired up on the phone is sending information back to Mother China. You really wouldn't know for sure
      since most if all that the CCP wants to listen in on, ALL of communications that support their spying apparatuses
      U.S. Allied Countries, you name it!!! Case and point with the DJI drones in their spying operations (NO JOKE) but
      an absolute fact....each and every time that you fire up their app, your phone device phones home to the CCP,
      such as to ask permission for the DJI drones to operate AND data packets as such things as location, mapping,
      time, aerial views, altitude; you name it, is recorded and packets forwarding take place. The common person
      does not know this and this type of spying presents a HUGE security risk for all nations!!! This was discovered by
      us folks here in the states by the U.S. Airforce. Another example would be all these bluetooth enabled smart watch
      /activity trackers that the troops were wearing while on duty around our military duty stations back in the states also!!! Hells Bells, even the built in microphone if it is so equipped can clearly pickup and further exemplify radio
      monitoring clear as a bell and hardly short of having unwanted vibration out of the ordinary and record audio and
      retain those audio clips and converted digitally as saved audio data that can be passed on by handing it off via
      bluetooth if this receiver is so equipped with transmitter and receiver. Sophistication in spying technology has no
      real limits in this day and age and China is so damned slick about it that it isn't even funny!!!@@ElectroBananasYT

    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.

    I was hooked as soon as I saw you open the package and started tearing into the radio without even putting in the battery and turning it on...Good job mate. I'm a new subscriber...Do you think it would pay to try and replace the speaker with a better one??? Sometimes decent radios come with such a cheap speaker, and I wonder if a more expensive "full range" 51mm/2in speaker would be considered an upgrade? As I also own this feature rich radio, and wonder if it would be worth the trouble.

    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.
