Frequently Asked Questions

What is the difference between FRS and GMRS frequencies?

GMRS and FRS share some channels, but FRS radios can only output 500mW at most. FRS radios typically have a range of two miles. Antennas and amplifiers cannot be legally added to FRS radios because they come with fixed antennas. GMRS stations can communicate with FRS radios through channels 1 through 7 which overlap with GMRS.

What frequencies are used for GMRS simplex channels?

Note that the old GMRS channels (the 462 MHz splinter channels and the 462/467 repeater channels) were not required to narrowband. FRS channel numbers commonly used by 22 channel radios are shown in the leftmost column.

What bandwidths are used for GMRS frequencies?

Among the first 22 channels shared by FRS and GMRS, The bandwidth of FRS is all narrowband 12.5KHz. However, GMRS except for the 8th to 15th channels which are 12.5KHZ narrowband, the rest are 20KHz wideband.

What is the maximum power for GMRS frequency channels?

As for the GMRS mobile radio, from the 15th to 30th channels, a total of 16 channels can have a high power of 50W, while FRS does not have mobile radio mode. Among the first 22 channels shared by FRS and GMRS, The bandwidth of FRS is all narrowband 12.5KHz.
