  15. Hi
    I have an 18 month old RT90 transceiver.
    The receive audio in the Analogue section is not working, transmit is ok, just no signal or audio is able to be received when tuned to an analogue channel, both in 2m and 70cm,
    Digital (DMR) is fine in both transmit and receive.
    My amateur call sign is VK3UV

    1. hi Bruce,
      so sorry for this, if possible, would you please send your radio’s codeplug to us?
      we will check the settings for you, and please tell me which channel with the analogue mode not working.

  16. Have a number of RT7 radios which I use in conjunction with other radios 777.
    Four of the RT7 seem to have locked Beat Shift into their program and can not be used with rest of radios.

  17. I have an RT628 which is stuck with VOX mode on and I cannot find a way to reset it. Here is what I have tried so far:
    1. Pressing the PTT which should turn off the VOX but doesn’t
    2. Powering off, removing batteries, pressing PTT to reset, turning back on, but VOX still set and no reset happened
    3. Powering off, pressing menu at same time as power button to turn on, but no reset happened
    4. Powering off, pressing menu to try to start that way (from another comment above) but won’t turn on that way
    Thanks for any advice which can be offered.

    1. I have the exact same issue. VOX is stuck on and I can’t get it to reset. Also, I don’t know if VOX is causing the problem, or something else, but it does not seem to be transmitting or receiving either. Hopefully there will be a reply.

  18. need the factory reset file for RT27V… I messed something up and the radios arent communicating with eachother anymore, and I can’t figure it out.

        1. hi, sent them by email!
          Because I don’t know your RT3 version, so I add 4 versions for you!
          Please check your RT3 version, then use the right version.

          Best regards

  19. I used the RT27 software to program my RT27V (two of them) before I realized that this is wrong. I cannot get them back to factory state and they will no longer work. Thanks for any help.

      1. I tried what you suggest, I used the RT27V software and uploaded the default to the radio (no read, just write) and no luck. I was sure to remove all files from the other (RT27) software and it still does not work for me. Same results.

  20. It’s a 5 channel radio (RT27V MURS). It does not work correctly. It does not work. It turns on, when I try to transmit it will not transmit voice but it does transmit a signal (your voice cannot be heard on another radio). It is also transmitting too wide, I can detect transmit on a wide frequency.

    1. You mean your RT27v can transmit the signal, but you can not hear on another radios?
      and transmit too wide? what’s the meanings?
      If possible, would you please make a video for me? Then I will know your problem clearly, my email:

      1. I have the exact same problem as Rob Haag, and did the same thing. What was the solution to Mr. Haag’s problem?

  21. My RT27 PMR446 do not communicate with each other.
    TX works, but no modulation is audible on another device, nothing works.
    Devices are new.

    thank you

    1. Hi, if you have the programming cable, you can check the two radios settings on the software!
      Then change the different settings to same, they can talk to each other!
      Best regards

  22. Hi.
    I had no problem to program my H-777 with Windows 7 but with my new Windows 10 I cannot any longer.
    I downloaded the last version of the software and driver (universal driver) but I don’t know if this is OK as I am asked a password when I try to read or to write!!
    I never had to use a password to set my H-777 at the moment.
    How can I do now to programme my H-777?

    1. Hi, usually if the radio need password, means you sent the programming software!
      You can try the password: 00000000 or 43584450 to have a try please

      1. Hi I am having the same problem. I need a 6 digit password. It’s not allowing me to read or write. I tried the passwords you mentioned but those are too long. I need a six digit.


    1. Hi, we are so sorry for this!
      When you met this problem, you can turn off your radio,then press the sidekey buttons (2 buttons)at the same time to turn on your radio!
      Then you can have a try to upload the codeplug again!

      Best regards

  24. Hi Retrevis:
    I am trying to upload the new frequencies to my RT23 Radio but it is calling for a password using the programing software for RT23. I do not remember ever putting a password in. I am trying to do a factory reset to eliminate the password. How can I do it? Thanks.

  25. Hello!

    I’m trying to update my RT3S w GPS from 18.03 to 18.16. But after successful update I unplug my radio and switching it on, radio shows only boot image and nothing to do. Programming software is working properly.

    1. hi,
      wouldyou please try again to update the firmware, maybe there is something wrong with it, and please make sure you choose the right verison, if your radio is GPS version, please choose GPS

  26. Hi There,

    I have a Retevis H-777 and i need to reset the Frequency, when i do this it’s asking for a six digit Password, what would this be

  27. Good Afternoon from the Philippines,

    Recently purchase one unit of RETEVIS RT3S with GPS. I just wondering why the callsign of the calling station does not reflect in the radio display like other radio that you can see the callsign of the calling station. Can you help me with this?

  28. Buon giorno, da tre anni adopero retevis rt3 ed rt3s. L’ultimo rt3s mi da molti problemi, non sempre trasmette, in analogico non trasmette anche se il led lo da in trasmissione. non si riesce a caricare il file csv, mi indica il successo di installazione ma in realtà non e vero. ho provato con firmware 14.04, con 16.06, con il 17.12 ed il 18.11 ma non ho miglioramenti. cosa posso fare? Grazie IW3HLT Milan Gianni

    1. hi, for your RT3S, when you upload the csv contact, please make sure your radio’s firmware is the CSV version.
      And click the menu write contacts-import-choose the csv file-write, then waiting for it, when it says success, you can check the contact on your radio.

  29. Now this password is OK but I have another issue.
    I can’t change the frequency values of each channel. All I can do is to change the CTSS, DCS etc with the mouse, but I can’t change anything with the keyboard. I found no mean to edit the frequencies

  30. My RT23 seems to not be recognized by any of my computers suddenly.

    When I do a factory reset (push PTT and button 2 on the side of the radio) as above I get OLDSTTS on the display. What do I do next?

    1. Hello! Have you checked the USB port of your computer? Could you please send us a video of it? here is our Thank you very much and have a nice day!

  31. I have retevis Rt3s – however I am unable to see see the power in the Radio settings, eve though it is ticked in the software program. It is in the Low and nothing I can do can change it.
