Stuck it in the car running APRSdroid
Do you use it with a SIM or via a phone hotspot or other wifi?
(My understanding is, you can either fit a SIM or connect to Wifi. I'm
curious about the amount of data used if you opt for the former.)
Also, do you know the difference between the TM7 and the TM7 (Aviation)-
I can't find details on the net.
At the moment it is tethered to the car/phone WIFI but I've been thinking the same regarding getting a cheap data SIM, but don't know how much data it'll use.
You can fit two SIM's in the bottom of my TM8, not sure about the different models. They're all the same though - android phone in a mobile form factor with mic and PTT. The only difference I can see between TM7Aviation and mine is a different type of DC jack on the back. The one on mine is useless, ripped it out and fitted a fly-lead instead.
I see Martin Lynch is wanting £190 !! for them
don't think I paid half that for mine but that's inflation for you.
