The only other possibility from Whistler (with Phase II and X2-TDMA voice decoding features) would be the Whistler version of the PSR800, which has yet to be announced officially.
Other than the GRE PSR800 and the BCDx36HP models, there are currently no other released models that will decode Phase II and X2-TDMA voice, and the PSR800 has been discontinued. Your other option is to purchase a PSR800 used.
I voted 'Yes, I’m a Techno geek that has to have the latest radios.'
I was leaning towards the 436HP but after seeing the pics and vids that are showing up, now I'm not so certain. That 536HP is a fine looking piece of equipment, and it would look a lot better next to my 15X than my RS Pro-197 would. Once I finish my move, and both are on the market, then I'll decide.
(and before someone says "buy both," I can't afford both so unfortunately I will have to choose )
I plan on buying either the base or the handheld version at some point. Thing is, there isn't anything in my local area that these models will let me listen to that my 396XT doesn't already allow me to hear. Yet....
I am going to wait to purchase a new scanner. I have no need for a new scanner as of yet until maybe late this year or early next year. I am going to sit back and see how all this plays out between all the new models coming out.
