-Everything starts by a script, with options commented out to start [[https://github.com/ha5di/DIXPRS|Dixprs]] instead of ''aprx''
-Dixprs seems to be moribund, the google site where help and information was available is gone. Dixprs works well, and I can switch back to it
-whenever I want to, but ''aprx'' is at least still supported.

-===== Hardware =====
-I use a [[https://tnc-x.com/TNCPi.htm|TNC-Pi]] attached via the GPIO serial port connections. Something had to be done
-to stop the serial port having a Linux Console attached, in the boot configuration, but it's been many years and I
-can't remember the details.
-At present the Radio in use is a simple FT-60R handheld, at 5W output.
-===== See Also =====
-The iGate appears on [[https://aprs.fi/info/a/GM4SLV-2|aprs.fi]] as GM4SLV-2.
