Hi Carl,

The simplest solution for counting, if you have a PC with a good sound card, is just to use a mini-microphone from the PC taped over the speaker of the rad monitor - then obtain DAQ software that uses the soundcard for input. There is a lot of this for free and for a fee on the internet.

In general, this solution works surprisingly well up to 20-40 khz. If you are getting many more neuts then that, then you probably need to think first about shielding.
