That's definitely sending 0's. I see you're using USB serial cable mygeiger mode.
ls /dev and report what ttyUSB's you have. Probably ttyUSB0?

sudo screen /dev/ttyUSB0 2400
should print serial data out to the screen. Wait for 30s. Press ctrl-a then d to close.

If you see weird characters then try 9600 baud instead.

ttyAMA0

Baud of 9600 shows 0s when using screen.

The pyradmon config file is set to a baud of 9600 and is using ttyAMA0.

It ran perfectly up until my first post of this thread.

Ok, so the CPU in the kit is not counting the pulses from the geiger tube. There must be an electronic fault between the tube and the CPU. Usually there is a buffer of some kind, a transistor or something.

Can you dig out or find the counter circuit diagram?
