Other facts include Radio Shack scanners get firmware updates later then the Whistler do and is subject to approval from Radio Shack, it ensures that no updated firmwares cause problem, by way of Whistler owners, they are the beta testers for new firmwares.
I suspect, so Radio Shack does not have to flush out a Scanner support team, if there are no "negatives", when the firmware seems stable, then it will be furthered to the powers that be, at Radio Shack.
I wouldn't expect a firmware release until after NXDN is released. Mind you, it shouldn't take the 28-29months, that it's taken another to release an Android App or the 12 months to get a working firmware to make the WIFI dongle work, for a control software that was non-existent for an additional 11 months
So stay level headed and be patient, both parties still have a better track record than our the other manufacturer who failed miserably, while they spent valued resources printing Manuals for thousands of scanners for 102 curmudgeons owners who "would never buy a scanner without a paper manual", instead of sourcing quality parts, with proper QA done to them.
