TK-5220 HT with KMC-47GPS Mic - it sends but nobody receives

[KC7JKJ]

I'm new to this website and these forums are great. Just from reading several posts here I've finally gotten my TK-5220 to send the position data from the GPS mic, but I can't get the other radio to receive it yet. I'm testing with these two radios for now, then when I get it figured out, I'll program the other 9 in the group.

It must be something I'm missing in the software (KPG-112D) for programming the radios, or do these radios just not receive each others position data like I'm hoping. These radios are for our Search and Rescue group, but I hope to expand the knowledge to our Sheriff's Dept.

Any help or suggestions?

Thanks in advance.

I'm messing around with GPS on the NX-200/NX-700 line. It doesn't appear you can send GPS data to other radios for display. You will need to assign a target radio to receive the GPS data in software. The target radio will in turn spit out serial data through a com port to an external mapping program or whatever.

The only thing I can do is program a button for GPS and see the location of that radio.

If anybody knows how to do what you're asking, I'd like to hear about it also...

Me thinks you must be right. I just tried programming "ALL" in as the target radio and tried to send. The receive radio "hears" the signal (squelch is broken and the receive LED lights up), but nothing is displayed either on the position display screen or the main screen.

I have just ordered the KAS-10 Fleetsync software so hopefully that should help clear this up and finally validate what you posted as the final answer. I think we both hope you are mistaken, but I'm afraid you are correct.

I guess it's all how the firmware is written and how the radio operates. Most Fleetsync ops require an ack, so you dial in a individual radio or use a default target radio to send data. A plain GPS blip is a broadcast only and doesn't require an ack. You would think then it would be easy to pick that up and put it on every radios display, but if that option is not available it's, well, not available.

gps data can only be sent to 1 radio and that radio has to connected to kas-10 or similar

Right, that is what it was intended for. Sending latitude and longitude to an LCD display isn't very useful. Sending it to a computer where it can be displayed on a map for a dispatcher is useful.

What you would need to do if you wanted to make this work is connect to the comm port pins on the mic connector on the portables, or the DB-25 on the back of the mobiles and have a display that would do something with it. You would need to set up the comm port correctly on all radios, and program the sending radios to send to all the other units.

Try kenwood kas-10 works a treat

I still plan on writing software for the gps into the GIS map server its just been put on the backburner. I'm fixing to get a start on it though.
