The NASA Wallops club just got in 11 of the MD-380's and so far we love them! I built up a default profile and loaded each member's radio with it. They each got a programming cable with their radio, so they can make any changes, additions, whatever they want. We have the basic function of our DMR repeater using both timeslots, as well as analog in dynamic mixed mode. So far, everyone is using DMR and love it. I think it's really going to catch on here.
I did notice a few quirks:
1. When you're in a menu and the backlight goes out, pressing as button brings the backlight back on, but it exits you back to the home screen. Annoying when you were trying to type a message or something similar. You lose what you were typing.
2. When I am editing a message, I can seem to get delete/backspace to work. I end up jumping out, then starting a new message, praying I don't make a keystroke error again.
3. When sending a message, when the person you're sending to is not in range or the radio is off, it seems to hang up because it never sees a confirmation of message received. In many cases I have to power cycle the radio.
For the backlight issue, I understand why the delay is there and then it turns it off for battery reasons. I would like to see an option to have the backlight on all of the time WHEN IN A MENU. Basically, if you are in any screen other than the home screen, the backlight auto-off feature should be disabled. Once you go back to the home screen, then the auto-off feature would be enabled again.
Just my observation and $0.02, but overall an amazing radio for the price!
