I also think NX-_40 radio could have a few more features. Biggest gripe I have is that I can't scan between digital channels and analogue radios. This has given me a few headaches as many clients have multiple channels and not all are digital and they want to monitor all there channels.
If you compare other manufactures entry level digital radios they are all cable of this, Motorola, Icom, Hytera etc.
Maybe they have changed this in version 2, not sure.
