Not to be a doomsayer,but I highly doubt ever seeing another true scanner come down the highway. I have felt this way since the passing of Paul Opitz, and the last Whistler simulcast copy fiasco.
Sadly, I have to agree. The top-of-the-line Whistler and Uniden scanners are probably doing exactly what 99.5% of folks are looking for/listening to. At least as far as I can reckon, simulcast notwithstanding. And incidentally, perhaps because I am using smaller mag-mount antennas at or near ground level, even here in the heart of New York City, simulcast is not a major issue for me.
You can always opt for an Icom R8600 if you don't mind spending $2500+ USD. You'll get plenty of bells and whistles, but you WON'T get DMR or trunking capability.
The AOR DV1 is another nice option, closer perhaps to a "scanner" than the R8600, and with more digital modes available. But no trunking.
I've got a few extra $$$ that I would be happy to spend if Whistler (or anyone else) came up with something new and innovative. But I can't really think of anything they could possibly add to the TRX-1 or TRX-2 that would get me to fork it over.
Won't it be interesting if Whistler (or Uniden) came out with a receiver with a spectrum scope, full digital modes, and a form factor similar to the R8600? A receiver that would also handle trunking. But then again, at what cost?
