Original: Radio Comment Translation and Introduction
Recently, many friends are very concerned about Hanrongda's new radio 787 and have raised many consulting questions in all aspects. I have summarized these questions and answered them briefly based on my understanding of this radio. I hope that it can not only solve the questions in everyone's mind, but also enhance everyone's understanding of this new radio, and help everyone filter out the radio that suits them. Don't say much, the Q&A begins.
Q: Where can I buy the new Hanrongda 787 radio?
Answer: At present, this radio is still in the internal testing and final improvement stage, and has not been officially launched yet, and it is currently not available on major platforms.
Question: What is the price of Hanrongda 787?
Answer: The price is still unknown, wait for the official announcement.
Q: Want to know how long its antenna is?
Answer: The total length of the pull rod antenna is 32.5 cm, divided into 5 sections, made of stainless steel, and has good bending resistance.
Question: When will it be launched?
Answer: The specific date is not clear yet. It is currently in the sprint stage, and it is probably soon.
Q: How is the sound quality?
Answer: Compared with the same brand of products of Hanrongda, the speaker external sound quality is worse than 747, but not as good as 701. I specially used an ordinary headset with an impedance to test the sound quality of the headset output. When the volume is 0, I could not hear obvious rustling noise and the output was relatively clean.
Question: Can I receive aviation frequency?
Answer: No.
Question: Is there a headphone jack? Is it stereo? Is there any time to turn on the computer?
Answer: There is a headphone hole, on the top of the body, close to the pull rod antenna. The headphone output is stereo. There is a timed power-on function.
Question: Can the screen backlight be set to always light?
Answer: There is no introduction to the settings that are always on in the manual. I observed that any control for 787 can activate the backlight and turn it off automatically after 5 seconds of light.
Question: Can headphone cables be used instead of tie rod antenna?
Answer: I selected weak tables in the frequency modulation and short-wave band respectively for testing. The headphone cable cannot be used as an antenna and cannot replace the pull rod antenna.
Question: What battery are you using?
Answer: Please see the picture below for battery information. It is a commonly used lithium battery with a capacity of 800 mAh. The battery cover of the internal test prototype can be opened. Currently, the manufacturer is changing the housing mold. The mass-produced version of the machine will cancel the battery cover, and the lithium battery will be completely built-in.
Q: When using the Radio-C application on the phone to control 787, can the sound be emitted from the phone?
Answer: No.
Question: Is there an external antenna socket?
Answer: No, if you want to improve frequency modulation and short-wave reception performance, you can connect the simple long-wire antenna to the tie rod antenna.
Question: Is there a sideband on it?
Answer: There is no single sideband function, and the upper sideband cannot be received.
Question: Does Hanrongda have a desktop computer? Should it be powerful and replace ordinary small speakers?
Answer: As far as I know, there is no desktop computer yet, and now it focuses on multi-function portable machines.
Question: 787 has an audio input function. It can be connected to the computer through USB and acts as an external speaker for the computer, but it does not have an audio output function.
Question: I like the Radio-C software very much. Can it be used for other radios? Where can I download it?
Answer: I used Desheng PL990 and Hanrongda 701 radio for experiments. Radio-C software is not compatible with these two radios. It should be a software specially built for 787. The 787 instruction manual introduces the download method.
Question: The memory card has lrc lyrics file, can it be displayed on the mobile app?
Answer: I used the MP3 file and LRC file in the new concept English for testing. Only the file name is displayed on the mobile APP, but not the LRC lyrics are displayed.
Q: Does Bluetooth headset support?
Answer: Its Bluetooth only has the reception function and does not transmit function, so it does not support Bluetooth headsets.
Question: After closing, can I reboot with my phone?
Answer: After turning off the radio with the mobile APP, as long as the Radio-C program is not completely terminated in the background, you can also use Radio-C to restart the computer.If you kill Radio-C's background to run, you have to manually turn on 787 again and then connect to your phone with Bluetooth to normally use the various controls of Radio-C programs.
Question: Is there a meter band switching for shortwave?
Answer: Yes, in the short wave band, you can switch the short wave band by pressing the orange lock button frequently.
Question: What is the difference between Hanrongda 747?
Answer: The positioning of 747 is a broadband receiver. In addition to the standard broadcast band, it also covers the U-segment and V-segment used by the intercom, as well as single-sideband and aviation band. The 787 only covers the standard broadcast band, meteorological band and V-segment. There are no single-sideband and aviation band, and it cannot have multiple AM bandwidths available like the 747.
Question: Does the Radio-C program support iPhone?
Answer: It is not supported yet, and the manufacturer is working hard to communicate and negotiate.
Question: Is the reverse control radio function of the mobile phone useless?
Answer: I don’t think so. You can place the 787 at the window, which is conducive to receiving broadcast signals, and then use your mobile phone to control the 787 radio on the sofa, bed or other places indoors. This not only ensures good reception effect, but also does not need to turn back and control the radio, which is very convenient.
Q: Isn’t it good to use the radio APP directly on your mobile phone? Why use your phone to reversely control the radio?
Answer: Even large platforms such as Dragonfly FM and Himalaya cannot guarantee that all of your local radio stations will be included, especially in cities or regions outside the first tier, not to mention that they do not include short-wave stations from all over the world. From this perspective, radio APPs cannot completely replace physical multi-band radios.
Question: What is the Bluetooth distance of the mobile phone reverse control radio?
Answer: First, I placed the 787 on the windowsill on the south side, and then took my phone to the window position on the north side of my home. The phone was about 14.4 meters away from the 787. There was no problem in operating, and there was no lag. Secondly, the position of the 787 radio remains unchanged. I took my phone to the kitchen. It is about 13 meters away from the 787, with two walls in the middle. There is no problem in operating and no lag. Finally, I also tested it in the study, bedroom, bathroom and other places at home. There was no problem with the control. The Bluetooth function covered any location in my home without blind spots.
