Hi Thomas,

After the HRD-737 : https://swling.com/blog/2019/01/inside-the-hanrongda-hdr-737-wide-frequency-receiver/

and the HRD-747 : https://swling.com/blog/2022/03/paul-is-impressed-with-the-hanrongda-hrd-747/

here is the HanRongDa HRD-A320

Does anyone have any information about this new receiver released by HanRongDa?

With the WB band, this receiver seems intended mainly for the North American market.

I found this web page with interesting documents rarely made public:

HanRongDa HRD-A320 High Performance Mini All Band Radio Bluetooth Receiver User Manual: https://device.report/manual/7151781

The user manual is also available: https://device.report/manual/7174111

But what about reception performance? Who has tested the new HanRongDa HRD-A320?

Have a nice day. Back soon.

    Thomas: Have the RF320 and is very sensitive in SW MW FM WB specifically. Has a nice audio and a beautiful design. Hope Raddy takes this design and adds SSB and a stronger whip antenna because this a Awesome Emergency portable radio.

    Hi Thomas & Paul,
    The reception performance of this radio has been improved over the HRD-787 (alias brand Raddy RF75A) by expanding the reception band and by increasing the size of the main unit.
    The larger size of the main unit makes it less susceptible to radio interference caused by Bluetooth when using Remote APP.
    The DSP used is also the same, so there is no significant change in sensitivity.
    (There is a difference in sensitivity to the extent that the size of the antenna has been increased.)
    The battery is not a built-in fixed battery, but a popular 18650 battery, which can also be replaced.
    Amazon Japan seems to be ready to sell the product, and we expect that the product will be available in the U.S. at the same time.

    The version for North America is likely to be sold under the brand name Raddy RF320.
    A video of what appears to be a prototype version has been uploaded to YouTube.

    I’m confused when these many “off brand” very small market radios are introduced. How many can they possibly sell to warrant any unique R&D? They all must be clones of each other with a bit of plastic molding. The market for SW is small enough and anyone interested in a “semi” quality radios, at this stage of the hobby, will and should go for the established brands. Just my opinion…

      That’s a fair and logical opinion, but when it comes to collecting things, logic goes out the door, lol. I have like 20 watches. Some use the same movement (inner works). But I have different ones because of looks, style, something that caught my eye. To some people a watch is just a tool, but I like to look at them and see them as more than that. I rotate through them based on what catches my eye on a given day.

      I suspect it’s the same thing with regard to radios. I personally would buy this radio for the unique looks if it were a bit cheaper. The buttons, knobs, etc., make it stand out.

    Hi Thomas & Paul,

    Functionally, this product expands the receiving band of the HRD-787 and adds functionality to search for broadcast stations using two types of pulley control (potentiometer/rotary encoder).
    Notably, the rotary control using a potentiometer (movable range 225 degrees, actual range 180 degrees) can search the entire band currently being received (meter band).
    However, due to specification limitations (rotary resolution), only rough tuning is possible for VHF/AIR/WB.
    Fine tuning is done with the shuttle dial or up/down buttons using the rotary encoding.
    To enable the rotary, rotate the rotary from the OFF position and turn on the switch linked to the potentiometer.
    (Mechanically, it is a potentiometer with a switch.)
    To disable the rotary, press the “operation lock” button once to put it in the operation lock state, return the potentiometer to the OFF position, and then press the “operation lock” button again to release the operation lock.
    This operation is not necessary to make fine adjustments with the rotary in use.
    It is a nostalgic experience reminiscent of analog BCL radio operation in the 70s and 80s.

    From the person who performed the operation on the actual device and translated the instruction manual. ?Not the English version)
    Pseudo name is “David”.
