|Robotic reconnaissance devices|
may use 70 centimeters but must
limit signal bandwidth to 100 kHz.
The FCC in mid-November denied an ARRL appeal of its 2010 decision to permit robotic reconnaissance devices used by public safety agencies to operate in the 70-centimeter band, on which amateur radio is a secondary user. However, the ARRL Letter says the Commission made it clear in its ruling that the devices' signals are limited to a maximum bandwidth of 100 kHz.
