-===== 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.

-===== See Also =====

-The iGate appears on [[https://aprs.fi/info/a/GM4SLV-2|aprs.fi]] as GM4SLV-2.
