Great info!

My problem is, H's laptop and cell are both properties of the company he works for, so I'm not sure I can legally do anything about intel on those. The voice recorder and such, sure.

The mobile phone jammer - does that mean no cellphone would work in the house or can I just block his? Although, I have to say - I never catch my H on the phone or texting or anything while home. (That I see of course...but I've been very observant and done some spying when he's in the home office.)
