According to posts on social media from National Scanning Magazine, the Whistler Group, parent company of Whistler scanners, has apparenlty shut down operations. You can read some of the details here: https://natcommag.substack.com/p/scanning-whistler-apparently-out-of-business
For many months now, Whistler scanner users have been complaining about being unable to update their scanners from the on-line Whistler server, and there has been little or no new scanner stock available for some time.
The Whistler scanner line was previously manufactured and sold by the GRE Corp, but some years ago, GRE sold their IP and scanner line to Whistler Group, out of Arkansas.
It remains to be seen if there will be any scanner manufacturers other than Uniden in the market.
