Retevis H777 is classic model, very high performance price ratio, makes it very hot sellings for years. We have not a few customers order this model consistently for big quantity. In Retevis overseas warehouse, this model is always prepared with enough stock, so it’s easy for shipping.

Now let’s go to business, do you know how to programme H777 when you get a new radio at hand?

Same Retevis radio model no. is with same default settings.
For new H777, just switch the new radios in same channel, they can communicate directly.

Programme H777 when you need make some changes:

Step:1  Please download and install H777 USB driver (USB Universal Driver) in RETEVIS official website https://www.retevis.com/resources-center/
Step 2: You need a programming cable C9018A
Step 3: Connect your H777 with you PC, using progrogramming cable
Step 4: Turn on the radio H777.
Step 5: Now we come to H777 software interface

Step 6: Choose the correct communication port
(check in computer-device manager)
Step 7: Click” Read from Radio” in “Program” Column
Step 8: Write the date, such as “RX frequency”, “TX frequency” CTC/DCS DEC and CTC/DCS ENC in to the channels
For example:
RX frequency:462.2375
CTC/DCS DEC: 67
TX frequency 462.2375
CTC/DCS ENC: 67

Finally Step 9:Click “Write to Radio”. Then all datas will be save to radio.

    I am having an issue programming my H-777 to talk to my RCA XR150 radios. The information provided on the RCA radios have CTCSS at 67.0 and the CDCSS at 023, but the H-777 software will not accept the CDCSS at 023. Any ideas on what could cause the issue?

    I am attempting to update the configuration on my H777 but keep getting the “wrong password” error. I tried on Windows 10 and Windows XP, fresh system, fresh install, fully updated. Using the “Universal USB” driver and H777 Retivis programming software. I have tried 0000000 5000000 and 9999999 as well as blank passwords. Any recommendations would be appreciated.

    Thanks and kind regards,
    Daniel

    The current version is flawed in some way that causes all communication between the software and radio to fail. I uninstalled it and reinstalled the older version and was able to program my radios using my saved file. Also, why was the saved file changed to .xml instead of a .dat file? I will not be using the new software due to this issue.

      Hi, may I know your radio model? H777?
      We have updated the H777 software, now the new one saved file is .xml
      If you still want the old software, we will send you one by email, then you can write your file to your radio, then use the new software to get from your radio, then save it as the new file with .xml

      Let me know if you need or not! My email: partner@retevis.com

      best regards

    Hi I’m having trouble with my radio it’s a model: H777S .. everytime we plug in the headset it doesn’t work, but when we unplug it, it works

      hello! you can check the headset is matchable or not, and check the headset plugin fully, or change other headset and have a try. if they do not work, it should be the product problem! You can contact us through our Facebook and e-mail:partner@retevis.com.

    I can read the data out of the radio, but I can’t change the frequencies – the field just will not let me type anything in. Any ideas? Can you email me the old version of the software? Some people indicate that the old version works.

        Thank you – I did receive the new file you sent me, but it was the same version as on the website, 1.0.2, and it has two problems: I can’t change any of the frequencies and I can’t write to the radio, it just gives an error of “Failure”. Do you have an older version of the software you can send? Other say that the old version works better. Thank you!

    This software clearly does not work and I don’t understand why you keep telling people to do the same thing over and over again. Please send me the software that actually works to write to these radios, I purchased another set of 20 and need to program the old ones to match the new ones.

    1) Kindly send me link to old version of software. I can only read my radio with new software. Cannot write to radio.

    2) Please explain how to get low power setting to work. Regardless of setting high or low Tx power, my H-777 radios only transmit in high power around 4 Watt.

      I originally tried this version: 1.0.2 2020 built on 2020.
      It will read the radio but fails when trying to write data to the radio.

      You just sent me this version: 1.1 dated 5/29/2018
      When I try to read the radio, it gets to 20% then crashes the program

      Here’s the serial number of the radio if it helps: 16H7770193257

      Any ideas what going wrong ?

    I have reprogrammed my new H777 units to match the frequency of the old H777 units. The lights turn green to indicate it is receiving a signal, however I cannot get any audio to go through.

    I can successfully reprogram older model to older model, and newer model to newer model, but cannot get the old and new to talk succinctly, even though the software reads them on the exact same channels and setting.

    Using correct cable and software version H-777 1.1 (2018)

    I am having a similar problem. I’ve purchase several dozen of these radios over the last three years but can’t current version of the SW to write to any of them. I downloaded latest version from Retevis site. Once the proper COM port is set and I use the BF666S password I can read from the device. SW lets me alter settings but it won’t write to the device. Are the specific settings or a different version of the SW required to write to older versions of H777 handset?
