I also bought a TYT 2017 - without handling it first. I have to really big issues with the radio
The track ball is terrible - This should be a deal breaker for most. Inconceivable that any design engineer would choose this over a standard 4 or 5 way joystick / button combo.
The implementation of Zones is terrible too. Unless I have not been doing it right, you must apply one zone for both bands. Granted, there can be hundreds of zones, but you can't have one zone of say 16 UHF DMR frequencies, and another zone for 16 VHF FM. You have to have one zone that has all the chosen frequencies laid out in the one zone for 32 channels (16 UHF and 16 VHF). This works if you only have a few channels, but if you want to swap a zone of rail or marine VHF frequencies, and keep your DMR zone active on the other band, you can't. You have to make a new zone with the UHF DMR AND rr or marine channels included too. A more granular approach would have been much better.
All in all - I'll keep it, but I may not use it as much as I thought I would.
