fixes by Kirk and Phil in October (yes I know!)
ref station - had old version of gwstation.py
9:58:25 on Aug 3rd was last time it had run... so no GPS files were recorded.
if you power cycle ref you need to set the date with "date" and "gum-settime"
batV reading is 0.7V higher than the real BatV - but its not serious
New gprs antenna on ref - inside plastic pipe
tested Wifi link from Holmur to cafe (18km) with 500mW amps, cisco at one end (set to 50mW as recommended by amp) and usb-wifi at the other end.
