Success.
I'm now displaying 24 hour rainfall in mm to one decimal place in the
place previously occupied by humidity.

Ok, I was on the right track with my alteration to db.c and, my
weather stations now display rainfall instead of humidity - R:2.0mm.
I now have to figure out why the reading is about 4 times actual
rainfall.
Back to the drawing board.

Dave/All,
wview is not suited to my need to display 8 wx stations on a regional
map.
I've been poking around in db.c an found what appears to be the code
to display Humidity. The variable wx_prec_24 appears to be daily
rainfall so, substituting for wx_hum and, converting to mm (on the
assumption that imperial is used), I end up with the following from
line 2825 in db.c
if (!Display_.temperature_only) {
if (strlen(weather->wx_prec_24) > 0) {
xastir_snprintf(wx_tm, sizeof(wx_tm), "R:%.1fmm",
atof(weather->wx_prec_24)*25.4);
strncat(temp_wx_temp,
wx_tm,
sizeof(temp_wx_temp) - 1 - strlen(temp_wx_temp));
}
Would anybody care to comment about this proposed alteration to db.c
to display 24 hour Rain (R) in lieu of Humidity?

Dave,
Thanks for the thought.
It's currently 3 am and I'm not in thinking mode. I will take a look
at wview at a sensible hour.
Yes, I do run Linux - Mint 9 KDE on a couple of machines at home and
Debian v4.0 at the radio station and for my aprs gateway at home. V4
is a bit old but it isn't broken.

Ray,
Most of the work may be done for you already!
Have a look at http://www.linuxjournal.com/article/10782
If you are running Xastir then you are running Linux and wview is a
Linux program.
Wview reads CWOP data here in the US so it should be able to read BM
data in AUS.
Just a suggestion that might be of use.
Anyone else have a better idea?

I'm after some direction.
I run xastir in the studio at the local community (public) radio
station, to provide weather details at regional airports. Xastir runs
under the stations AR Club callsign of VK2WET. Look here to find out
why it's VK2WET - www.tankfm.org
I'd like to be able to display total daily rainfall, as available at
the airport sites from our Bureau of Meteorology either, in addition
to the existing displayed items or, as a replacement for humidity.
I'm
not a programmer but I'm not adverse to 'having a go" if some kind
soul can point me in the right direction.
