Simon, You are correct in your original assumption that w34realtime.txt is based on the Cumulus realtime.txt specification. It has had few additional values added but nothing to do with UV measurements.
According to the Cumulus specification position 44 should be UVI but the value you have there is clearly not. I used to have a similar device to you which is a clone of Fine Offset, from memory it did not actually measure UV directly but was a derived value. I always used to use the HP1000 driver from Aussie Susan and cannot recall having any issues with that. One quick check you could make which would eliminate any issue caused by weather34.py is to disable weather34.py and install the crt.py and check the realtime.txt out put from that. If you still have the same issue, I would look at the driver you are using.
