wow nice tool...

Is it possible to make a configuration like always receive on xxx MHz 
when signal is heard report a DF-format on 144.800MHz or whatever aprs 
frequency you are using?

Then we can use 4-5 devices like this on every mountain top and 
listening for the repeater input frequency and plot a position on where 
the user are.

If this is possible it would also be nice if you can send a command to 
the device to toggle between the mode you are describing and what i 
mentioned. You might have to send this command on the repeater 
inputfrequency but this is not a problem as it's a short burst.
