  1. 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?

  2. 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

  3. 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.

    1. 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
