The Radioddity GD-77 Dual Band Radio

The size delivers a comfortable fit in the hand. It has really good audio on both analog and DMR. The RX audio is just as good.

The programming software can be a little tricky, but I had DMR experience and figured it out easily. Since this was purchased by my cousin, he says there has been some output power loss after updating. I have updated this radio twice, and have not experienced it, so I feel there may have been some user errors behind some of it.

Finding one on the used market may be your best bet, the newer GD-88 is available now. If you can spend twice as much, than I highly recommend the Anytone 878. It is the clearest DMR radio I have heard to date.
