Ailunce HD-1/Retevis RT-3S CPS & Firmware Update



https://tgifnetwork.createaforum.com/index.php?action=downloads;sa=view;down=46

 After buying my new Retevis RT-3S, I had to search for 2 days for a UART cable driver that would work with Windows 10 or 11. A friend finally told me that Ailunce and Retevis radios were made by the same company, and the driver, CP software, and
firmware updates were available on the Ailunce website. So here 'tis...hope this saves someone else some time. Please note that there are 4 different versions of firmware! . The RT-3S is available with or without GPS capability, and versions
with either 100,000 contact memory positions, or 10,000 contact memories, and 8 hour audio recording memory. BE SURE you are using the correct firmware upgrade, or you will find yourself owning a well-built, attractive high-tech paperweight.
