We do have costs for a new run of tuners from the original manufacturer now, and are looking into it. Stay tuned for more news.
Weatherband is only applicable to the USA, though, as the frequency band in question isn't used elsewhere. This also makes it hard for us to test
I suspect no more will be made with the weatherband module (it's not the "normal" part, they just happened to have some spare previously) - so people who really wanted a weatherband capable unit would have to swap their tuner with someone who wasn't bothered.
