SUMMARY: This document contains corrections to the final regulations 
(PR Docket No. 92-235, FCC 95-255), which were published Wednesday, 
July 19, 1995 (60 FR 37152). The regulations related to revisions of 
the private land mobile radio spectrum below 800 MHz.

EFFECTIVE DATE: February 5, 1996.

FOR FURTHER INFORMATION CONTACT:
Ira Keltz of the Wireless Telecommunications Bureau at (202) 418-0616.

SUPPLEMENTARY INFORMATION:

Background

    The final regulations that are the subject of these corrections, 
revised the private land mobile radio (PLMR) spectrum below 800 MHz to 
promote highly effective and efficient use of the PLMR spectrum and to 
facilitate the introduction of advanced technologies.
Need for Correction
    As published, the final regulations contain errors which may prove 
to be misleading to some applicants and manufacturers and are in need 
of correction.

  channel bandwidth must have a frequency stability of 1.5 ppm. Fixed   
  and base stations with a 6.25 kHz channel bandwidth must have a       
  frequency stability of 0.1 ppm.                                       
\8\ In the 421-512 MHz band, mobile stations designed to operate with a 
  12.5 kHz channel bandwidth or designed to operate on a frequency      
  specifically designated for itinerant use or designed for low-power   
  operation of two watts or less, must have a frequency stability of 2.5
  ppm. Mobile stations designed to operate with a 6.25 kHz channel

    6. Section 90.267 is amended by revising paragraph (a)(3) and 
adding paragraph (a)(7) to read as follows:


Sec. 90.267  Assignment and use of frequencies in the 450-470 MHz band 
for low-power use.

* * * * *
    (a) * * *
    (3) Stations are limited to 2 watts output power and will be 
licensed as mobile, but may serve the functions of base, fixed, or 
mobile relay stations.
* * * * *
    (7) Antennas of mobile stations used as fixed stations 
communicating with one or more associated stations located within 45 
degrees of azimuth shall be directional and have a front to back ratio 
of at least 15 dB. Except as provided in this paragraph (b)(7), the 
height of the antenna used at any mobile station serving as a base, 
fixed or mobile relay station may not exceed 7 m. (20 ft) above the 
ground level.
    (i) No limit shall be placed on the length or height above ground 
level of any commercially manufactured radiating transmission line when 
the transmission line is terminated in a non-radiating load and is 
routed at least 7 m. (20 ft) interior to the edge of any structure or 
is routed below ground level.
    (ii) Only sea-based stations, and central alarm stations operating 
on frequencies allocated for central station protection operations, may 
utilize antennas mounted not more than 7 m. (20 ft.) above a man-made 
supporting structure, including antenna structures.
