Friendly reminder to avoid using frequencies allocated to Amateur Satellite Service

The Brandmeister Support Team frequently receives requests to prevent routing traffic to devices operating within the portion of spectrum allocated by all three ITU regions for Amateur Satellite Service. This is due to QRM caused by DMR signals on these frequencies.

While the Brandmeister DMR development team is not currently considering restricting traffic based on device frequency, we strongly advise setting your DMR hotspot or repeater frequency outside of the 145.8-146.0 or 435-438 MHz segments. It’s crucial to note that even low-power transmissions can cause interference when a satellite passes overhead and has a clear line of sight to the device’s antennas.

Thank you!
