I'm reaching out to the barometric pressure geeks to ask this question. I have 2 different pieces of electronics that both use barometric pressure to measure altitude changes. When i have them both turned on at the same time, one of them doesn't register the altitude. Can the 2 units be sending out a similar signal that conflcts with each other? I've searched the web for answers but can't seem to understand what I'm finding.

Any technical experts out there have some input?
