Very high reading at Tocsin_bang

Forgot to go offline when I did some testing. I had been cleaning the area round the tube connections with IPA, then when I switched back on it went crazy.

There's still some kind of issue. Counts are still way too high. I need to do some work on it, trouble is my new counter isn't ready, still needs quite a bit of work done, and I have other stuff to do as well.

Seem to have got it sorted. Two joints re-soldered, plus a good clean all round. Counter is also back in its case.
