I have a 2024 manufactured date SDS200 in my collection along with previous year manufacture dates. I can't report the "clicking noise" when I run my P25 or DMR systems in conventional mode with the latest firmware. I normally run them in OFT, but since I read this, reprogrammed a few of them conventionally as an experiment. It's possible it has less to do with firmware and more to do with a hardware conflict? Might have been a hardware change during 2024?
