I like the fact that the Whistler just works and customer support is awesome. I like that Whistler has stayed with us after they got our money. There have been many fixes and new features since the TRX-1 and TRX-2 have been released + fixes and new features for their pre-TRX scanners.
They sound great, they decode simplex better, NXDN, no false talk group ID's, record on a channel by channel basis, NXDN, software support for recordings, NXDN, ability to export recording information into excel via Don's AUParse tool, NXDN, and the ability to select specific mode while searching. Oh, and did I mention NXDN?
Whistler has won my money in the future simply because THEY ARE LISTENING TO US.
