" ... I get 100% out of all the scanners listed in my signature line ... "
David a 1 band Kenwood or Motorola walkie cost more than the X36 series scanners. The AOR wide band receiver cost $1,200.00 and still does not work as listed plus it does not trunktrack. Just how much do you think a scanner should cost for the features you want? I get 100% out of all the scanners listed in my signature line own and still use each and every one and waiting to add more. To answer the question if Uniden offered a new version of the X36's with TRBO and NXDN I would buy one Today.
TRBO is getting REALLY popular in my area. If Uniden (or any other brand) introduced a compatible scanner, I'd buy it immediately.
I suspect if anyone came out with a decent TRBO scanner, you would see a dramatic upturn in the use of encryption which is a standard feature on DMR.
That said, why don't you do what many others have done and just purchase a DMR portable and don't program the transmit frequencies in? You can get them for about $150 now.
I'm not sure a DMR scanner would encourage encryption. Encryption totally depends on the agency and how their administration feels about it.
