I agree with this statement. Ask yourself who you want to talk to. Are your friends using digital voice (DV) modes? If so, then you may want to buy a radio that will let you talk to them. Then, ask yourself if there are nearby repeaters that support DV modes. If the answer is "no", then there's not much point in you buying a digital radio.Personally, I'd avoid buying into an amateur digital radio.
Not any more. The TM-D710GA includes a GPS receiver built into the control head.I always had good luck with Kenwood amateur radios. I had the TM-D710 for a while (sold it to my brother in law). Good solid radio.
Keep in mind that (I think) you'll need an external GPS to feed the radio.
