akuperma -“If your scanner is operating illegally, shut up and stop scanning before you get arrested.”
It’s not illegal unless you do it on purpose.
“If her phone is operating on the wrong frequency (which is the only way you could be legally getting her conversations), tell her since her phone is broken (and she could get in trouble for it).”
She can’t get in trouble for this. What happens is the junky phones can’t stick to their frequencies and anyone with a receiver/scanner can pick it up. It happens more often with other handheld phones -you can pick up others’ convos if they are in range. Either buy an expensive cordless that can only be picked up by the base/cordless of that set or use a landline for privacy.
