There is a general fear in the backcountry Skiing community that any RF devices might impede or negatively impact the use of search and recovery beacons to locate buried partners in the event of an avalanche. Any documentation/speculation on any potential interference?
My take on this: these devices should be safe to carry provided the hardware is verified to not produce spurious harmonics (via FCC certification or other means). The 900Mhz band used (in the US) by these radios will not interfere with 457KHz signals used by beacons.
I wouldn't carry it in the same pocket as my beacon, but I would use this device--definitely excited to watch the project's progress.
