THx for the feedback. Now I can start to build my two pulse meters.
One for my electricity usages and one for my natural gas usages.

@AWI Do you mean, remove the radio from pin 2 and use it for something else ?

I am in the process of building a sketch where I want to use 2 pulse meters.
The Arduino has only 2 IRQ hardware ports.
One is already being used bij the radio.....

Any idea how I can solve this ?
