[OZAPRS] Remote digi/igate

I see it “supports” APRSDroid., not sure what that means, could only be the GPS data.

Will APRSDriod act as an Igate?

Does look interesting! I cant find a lot of info. How do you get to 4g network I wonder?

Anyone have one?

I've been wondering if something like the X1C5 Pro <https://www.venus-itech.com/product/x1c5-pro/>  might be an option for an iGate + fill-in digi.


Not that much more expensive than a PI + bits + SDR, although it depends on what you already have in the junk box :-)

Bit of a fork from the previous thread


While Grey Nomading it through the Centre, Kimberly and Gulf Country, I had plenty of time to think about this. A lot of it was "pie in the sky" dreaming, but I did actually lash up some hardware.

RPi 3B (It's what I had!), xastir

Boefang Handheld (IWIH)

OpenTracker running as a Kiss TNC ,,,

3G modem Dongle.

12V 7AH battery, converted Car USB charger (2 Amps)

10 Watts of solar.


Put it upon  the 'van at a number of places while we toured in the ute. iGate worked a treat except the power budget was negative. Lasted three days before the rig died of power failure. The effective range of the iGate was an order o magnitude better than the digi. 50W v 5W. Never heard or saw another station digi either. Turned off transmit, power budget marginally positive, a bad day would wreck it!


By the time we started down the Queensland coast we had APRS coverage, 'tho' still a few holes.


Played more at home.

RPi3B (waiting for my Zero)

SDR dongle

3G modem Dongle

pre-built image.

I have it running off a 5V bench supply atm, so I can monitor current etc.


Sure, it's rx only, but "if a tree falls in the forest.... etc" For vast streches of the Outback, a digi or messaging is a waste of time, money, equipment and precious power.


Xmas has intervened so the project is on hold 'till new year.


More as it happens
