Frequencies
MURS comprises the following five frequencies:
| Channel | Frequency | Authorized bandwidth | Channel Name |
|---|---|---|---|
| 1 | 151.820 MHz | 11.25 kHz | N/A |
| 2 | 151.880 MHz | 11.25 kHz | N/A |
| 3 | 151.940 MHz | 11.25 kHz | N/A |
| 4 | 154.570 MHz | 20.00 kHz | Blue Dot |
| 5 | 154.600 MHz | 20.00 kHz | Green Dot |
The first three are what's called "narrowband", the last two "wideband". MURS falls under part 95 and is not mandated for narrow banding such as those of part 90 in the public service bands by January of 2013.
Because previous business band licensees who have maintained their active license remain grandfathered with their existing operating privileges, it is possible to find repeaters or other operations not authorized by Part 95 taking place. These are not necessarily illegal. If legal, such operations may enjoy primary status on their licensed frequency and as such are legally protected from harmful interference by MURS users.
