Isn't the comparable Whistler model going cost close to $600.00?
There is no comparable Whistler model. Whistler has currently released PSR500/600 clones which still have the same shortcomings that line has. Their next release will be PSR800 clones and the fabled "PSR900" (PSR800 in a mobile case) clone.
You could call the PSR800 "comparable" to the x36 line, but that's like saying a Samsung GS5 smartphone is comparable to a first-gen iPod Touch - the feature set is completely different.
What is analyze anyway?
I have a theory that most of the complainers that Analyze is missing have this exact same question!
Analyze brings the functionality of programs like Unitrunker or PRO96COM into the radio. You can assess different parameters and definitions of various trunking systems and log the details to the radio's microSD card. In addition, there are several other utilities like an LCN finder for EDACS and LTR systems - in other words, you don't have to find the LCN order for these systems any more; just load the channels any way, let Analyze chew on the system for a while, and ultimately it'll spit out the right channel order. That's really just scratching the surface of what Analyze Mode can do, but it's all along those lines.
