* According to the US FCC all transmissions within the US in 25 kHz channels must use a

radio link rate at least 19200 bps. See the next section on US narrowbanding regulations.

US Narrowbanding Regulations

Beginning in 2013, new FCC narrowbanding regulations restrict UHF transmissions

within the United States. Data transmission made in 25 kHz-wide channels are restricted

to radio link rates ≥ 19200 bps. Voice transmissions are not allowed in 25 kHz channels at

all. There are no restrictions for license holders for (a) data or voice transmission in 12.5

kHz channels or (b) data or voice reception of any channel bandwidth.
