Thanks Mark.

The latest on the project is that I had xastir running successfully so I 
moved on to try something else. I was heading towards aprx; had it 
installed and sorted the config file when along came dixprs, a 
gateway/digi program written in Python, making it cross-platform.

I had dixprs running all night talking to aprsis. I've just added a TNC 
and an Icom IC2A so it "should" now be operating as a rx only Igate. 
I've yet to see traffic even though the DCD LED is reporting activity 
and my other rx is hearing traffic. Might be a config issue to resolve - 
something I'll deal with throughout the day.

dixprs keeps a database of information and sends (optionally) this as 
telemetry to the aprsis each 15 minutes. Look at vk2tv-4 on aprs.fi.  
Mention is made in the docs of munin, a program that creates wonderful 
colour graphs of various aprs traffic. It installed just fine on the RPi 
as a deb package but it needed up to near 80% of the processor. munin 
has now been removed!!

If you're tempted to try dixprs be aware that the station coordinates 
are required in decimal degrees and not the standard aprs format.

More later.
