I decided that i wanted a high end base scanner to add to my collection, i have a lot of dmr single channel and one cap + system. Some p25 highway patrol channels, and a couple p25 trunking. I first bought the trx2 because of it having the dmr free of charge. It arrived and i got it all updated and programmed, and hit play... First thing i noticed was the p25 sounded robotic so i tried tuning the p25 which can not be put in manual decode! I got frustrated at that and the software is from the 90s. So i sent it packing and spent an extra 30 dollars and got the bcd536hp it is arriving today and will be getting the dmr upgrade right away. I know how the uniden menus and programming favorites work and feel comfortable with it. When i get the dmr upgrade key how long will it take before i can listen? Or should it be instant?
