I have had a Kenwood TM-D700 for three years and have found it to be an excellent radio.
Kenwood have got it right with this radio.


I use the APRS mode all the time, mainly from my home QTH, it is connected to my computer and runs my APRS, Ui-View weather station all day.(APRS Automatic Packet/Position Reporting System is a system that displays your location on a map).


I also run APRS mobile, you have to connect the radio with a GPS unit. I use it mainly with RAYNET on exercises to keep track of the sweeper and other operators. (Sweeper the vehicle that goes round the course behind the last runner/walker and can pick up any who have fallen by the wayside), as you have seen on the Ui-View page.
By using APRS we can keep voice traffic down to a minimum and if there is an emergency we can direct the medic to the right spot, and be able to give them the sorties route .


To do this we need a good map, you can do this two ways, you can make a map by using one of the many map programs that are on the market, or you can run a program called Ui-Point, this runs with Ui-View. You need Microsoft Map Point to be able to do this. The map can go down to street level, so if you get your map spot on you can track stations right along the roads. You can see this makes the TM-D700 an excellent radio, but wait it gets better.


Now you are running the radio on APRS on 144.800 on band A, so band B is on 70Cms working on voice, but if you want to you can switch band B to 2M and talk on there, it will override band A till you drop carrier, but if you keep the offers short it all works fine.
