Sec. 90.259  Assignment and use of frequencies in the bands 216-220 MHz 
          and 1427-1435 MHz.

    Frequencies in the bands 216-220 MHz and 1427-1435 MHz may be 
assigned to applicants under this part provided the band is listed in 
the individual radio pool under which they establish eligibility. Use of 
these bands is limited to telemetering purposes only and all operation 
is secondary to Federal Government operations. Operation in the band 
216-220 MHz is also secondary to the maritime mobile service and 
operation in the band 1427-1429 MHz is also secondary to the space 
operation service (earth-to-space). Base stations authorized in these 
bands shall be used to perform telecommand functions with associated 
mobile telemetering stations. Base stations may also command actions by 
the vehicle itself, but will not be authorized solely to perform this 
function. Airborne use will not be authorized. Each application will be 
coordinated with the Federal Government by the Federal Communications 
Commission and is subject to such technical and operational limitations 
as may be imposed by the government. Each application should include 
precise information concerning emission characteristics, transmitter 
frequency deviation, output power, type and directional characteristics, 
if any, of the antenna, and the minimum necessary hours of operation.
