Radioddity GD-77: What's In The Box?

The radio comes with a 2200mAh Li-Ion Battery, user manual, charger and Antenna. The site did not say if a programming cable came with the kit so I ordered one just to be safe. I don't have a lot of experience with DMR radios but I think it's safe to say that unless tbe radio is stated, up front, to only need a standard USB ptogramming cable then make sure the cable is either included in the box or order one with the radio, it will save you a lot of future aggravation if you start off with the tight cable and don't even think of programming DMR from the front-panel unless you (a) do thst sort of thing professionally (b) have masochistic tendencies or (c) all of the above..

GD-77 Notes Specifications: The GD-77 is a Dual Band, VHF / UHF radio. The operating frequency range for the GD-77 is VHF 136-174 and UHF 400-470 MHz. The GD-77 supports analog (FM) operation as well as Tier II, Digital Mobile Radio (DMR) operation. The GD-77 will transmit on low power (1W) or high power (5W). The GD-77 will support 256 TX contacts, 16 RX contacts, 1024 channels and 16 channels per zone.

Display: A two-color LCD (blue-gray/white?). You can turn the backlight off but the display becomes almost unreadable. Instead, you can set the timeout value for when you want the back-light to turn-off. The display itself is adequate for an HT and will show about 10 characters per line.

Hardware: The GD-77 case has a nice, well-built, feel to it and weighs in at a little over a half pound in active use (i.e battery and antenna are attached). The GD-77 has a PTT button and 3 additional programmable buttons

Programming and Software: I would rate the custom programming software (CPS) and firmware as adequate. The specs shown above are based on the stock firmware. If you want to really make the GD-77 shine then you should skip the stock firmware and load the open source community firmware, OpenGD77. OpenGD77 opens up the radio with more features, better CPS programming and much easier operation.
