It may be that e.g. sysmocom has received one in the last few days (I'm travelling this week), but it doesn't appear to be something that many people have had a chance to try/test yet. Given that the product is as far as I understand at a very early stage, as far as I can tell, I would not have too high expectations on production deployments just yet. This is irrespective of the name of the product nor of the manufacturer. Especially as it is not a brand-new "base station product" consisting of an integrated solution from one vendor who will provide a tested, approved, working product consisting of hardware and software, but as it is - AFAICT - a SDR hardware only product where the user has to "build his own base station" based on several components - one very important of them of course being the actual hardware board. > With the USB3 LimeSDR, after a few hours I _always_ get a broken trx, > with lots of failure messages... I'm sorry to hear this. We're trying to address various problems related to LimeSDR devices for quite some time, but progress is unfortunately not as quick as one would hope, particularly as LimeSuite also evolves and every major version seems to behave quite differently, at least in the way how OsmoTRX is using the API. In recent weeks, Joachim has been making very good progress with help from Lime to resolve some of the most long-standing issues related to RF compliance of OsmoTRX on LimeSDR (phase noise, burst shape, ...). There should be a patchset pushed to gerrit soon which will address this one class of problems. However, this does not adress any USB stability related problems, which is a separate class of issues. We have to look at them once as a time. One thing I'm a bit missing here is: Where are your comprehensive bug reports about this in the osmocom issue tracker? Particularly with problems that manifest themselves only every few hours and hence are not quick to reproduce, we have to collect those issues and related log files, backtraces, ... in the issue tracker.
