Hello Thomas,

I have just received the HRD-747 I ordered a fortnight ago.

Of course, I quickly made some tests and I’d like to share two of them with you and the regulars of the SWLing Post:

1 – This is a recording made yesterday (23 March 2022) on 12125 kHz; RFA in Tibetan from Tinian Island; the signal is very stable, very clear.

The HRD-747 is sitting in the grass at the foot of a tree in a park! Nearby a pond. Only 6 of the 7 segments of the telescopic antenna are deployed.

My Locator: JN19cc – Locator Tinian Island: QK25TB – 13225 km

Recording:

2 – My second recording is of Radio Tamazuj in Juba Arabic on 15150 kHz 15h45 from Talata Volonondry. This recording was made in the same conditions as the previous one. Again, only 6 of the 7 segments of the telescopic antenna are deployed. The reception is still quite good, isn’t it?

My Locator: JN19cc – Locator Talata-Volonondry: LH31TF – 8526 km

My first SSB tests also allowed me to listen to Russian or Ukrainian radio amateurs in the 20m band. This little device seems to me really very promising.

3- I also made this recording made ton March 27, 2022 in a small park in my city (L’Isle-Adam – Locator: JN19CC) NW of Paris.

It is a ham radio picked up on 14328.80 kHz at 15h30 UTC. No other antenna; only the telescopic antenna of the receiver! 

The HRD-747 has 100 memories per band; this proved insufficient to store all the stations detected during the scan of the entire spectrum from 3.2 to 30 MHz … The scan stopped in the 19 m band!

First impressions? I am impressed by this tiny receiver (only 108 grams with its battery and strap).

I would like to point out that the first version of the manual which was proposed on the site is particularly useful to me. Indeed, most of the keys are multifunction. It’s a habit to get used to, even if everything seems to have been thought out in a very judicious way.

With my best regards. 73’s

Thank you so much for sharing this, Paul. Those results are promising, indeed! The audio sounds quite good in your recordings–especially for such a compact radio.

HanRongDa HRD-747: Frank creates an English Owner’s Manual

Hi Thomas,

Last week I acquired a HanRongDa HRD-747. Really astonishing – a good receiving mini portable with wide range and many features.

Therefore the manual is very important especially because there are only a few knobs to manage all functions.

In my opinion the paper manual is too small (or my eyes are too old :-)) and without textual structure. And no way to get it online. So i have made an english manual based on the original hoping it will be helpfull not only for me.

Friendly regards

Frank from Germany

Thank you, Frank, for creating and sharing this manual!

Many thanks to SWLing Post contributor, Mei Tao, who shares the following:

Hi Thomas:

Before the Chinese New Year, I received a prototype of the HRD-747 radio and was asked for suggestions on how to improve it. As far as I know, this little gem will hit the Chinese market in April.

Here are its major features and some photos:

  1. More like a handheld wideband receiver: covers UHF?300—520MHz), VHF?30—300MHz), AIR, FM (64—108MHz), SW, MW, USB, LSB, WFM, NFM, and AM.
  2. Based on a DSP chip?sensitivity and selectivity are excellent.
  3. SSB?selectable USB/LSB?reception with 10Hz step tuning.
  4. Multiple tuning methods: ATS, presets, manual tuning, auto tuning, etc.
  5. Equipped with tuning knob.
  6. Bandwidth is selectable.
  7. Squelch level can be adjusted.
  8. ATT control, external antenna jack.
  9. 1000 memory presets.
  10. Powered by BL-5C cellphone battery (removable).

Sincerely

Mei Tao

Thank you, Mei Toa! The HRD-747 certainly offers a wider frequency range that we’re used to seeing in small portable radios. I’m very curious how sensitive and selective it is in those higher VHF/UHF bands and if imaging or poor selectivity are issues.

Thank you so much for the preliminary info!
