Ham-ing it up!
So last weekend I was out in the truck and set the radio up to scan D-Star on the 70CM band.
There was quite a bit of activity, including a conversation between a gentleman in Georgia on a Kenwood TH-D74A hand talkie, and a gentleman in South Korea (not sure what radio).
Over 7,000 miles on a hand held 5W radio, and I'm listening to both sides, like they are riding in the truck with me.
That is pretty darned cool. :victory:
D-Star is just one of three really popular modes that use repeaters linked to the internet. Pretty much Kenwood, and Icom radios.

There is also Fusion which is Yaesu's system.

And DMR which was designed by Motorola for the commercial market, and has picked up a lot of interest on the Ham side:

These systems are not compatible with each other radio to radio, but there are people working on the internet side of things to help with that issue.
Because it is digital, the voice is really clear with little squelch needed.
Most of these radios do standard analog as well as digital.
The one thing I like about the Icom (I have no first hand experience with the other digital radios/systems) is how amazingly easy it is to use. The radio came programmed with all the D-Star repeaters already. Based on where the radio is, it will bring up a list of nearby repeaters by hitting "Scan". It can also be updated via an SD card, or a programming cable as needed.

Nice for someone like me who is time limited, and more a "user" than a programmer/hobbyist.
Here is the screen that comes up automatically when I tune into a D-Star repeater with a conversation going on.
The message (MSG) is whatever the radio operator wants to type in. The distance (DST) and compass are relative to my radio's coordinates.
