Fine Offset 1080 which goes for about 18 months on 2 AA Alkaline power cells.

Maybe, but in that 18 months the damn things only work 3/4s of the time That's why I'm here, I was sick of the continual data connection drop outs and data corruption.

The Heatsink is on the TX's LM7809 for the Stevenson screen fan (and IIRC the 433mhz module).

My Maplin N96FY (FO WH-1081) doesn't seem to suffer from any connection drop out at any time (unless I plug my RT2832/R820T Airplane scanner dongle in to the same PC! as it seems to emit and interfere at 433.9MHz! and completely wipes out every reading on my console!), the console sits on top of my desktop PC case, connected 24/7 by USB with Cumulus 1.9.4. I don't seem to get any data corruption (yet) either, except for one glitch of 92Km/hr wind registered as a one off, once.

My reason for using the WeatherDuino is that I wanted to add solar and UV data to Wunderground without having to buy the (so far unreliable) WH-3080. And I am not willing to pay 1,000 GBP for a Davis Vantage Pro2 Plus. My friend Jon in Kent (SE England) is in the next few days sending me his old Vantage Pro1 Plus that broke down a while back, I think the transmitter board on it went faulty and there are no spares (and a new transmitter board for the VP2 is like 165 GBP anyway, not that it is compatible in any way).

Davis ones are not immune from data problems, Jon's VP1 used to regularly (once per day it seemed) have a dip on the temperature graph down to -1 when the rest of the day's readings were about 10 to 13 degrees C, the Relative Humidity sensor would also malfunction regularly. Also his solar data and UV data never showed up in Cumulus, I still don't understand why, despite him insisting it was the Plus model with the solar and UV pods. Finally, his USB to Serial connection would regularly stop working with no explanation, since VP1 uses a serial port and his PC was USB only, needing a converter, and we tried 3 different converters with similar problems.
