- 219-220 NPRM issued
-
- The FCC has issued a Notice of Proposed Rule Making to create a new
- shared band for amateurs at 219-220 MHz. In RM-7747 the Commission
- would allocate 219-220 MHz to amateurs on a secondary basis for
- amateur for point-to-point fixed communications.
-
- The FCC says the new allocation would help alleviate crowding in the
- 222-225 MHz band and would facilitate establishment of regional and
- nationwide backbone networks for amateur packet communications.
-
- The FCC proposes requirements to ensure that secondary use of the
- 219-220 MHz band by amateurs does not interfee with primary and
- existing secondary licensees in this and adjacent bands.
-
- The FCC cites several commenters who supported the League's request,
- as well as one opposing it. The Association for Maximum Service
- Television (MSTV) said that no amateur operations should be allowed
- in the 216-220 MHz range because of a potential for interference to
- TV channel 13 (at 210-216 MHz).
-
- The FCC said that amateur access to the 216-219 MHz range is not
- feasible because of potential interference to other point-to-point
- services, and to TV channel 13. The FCC said that amateurs do have
- the technical expertise to design their packet systems to operate in
- the 219-220 MHz band without interference to other services.
-
- The FCC also agreed that power limits suggested by the ARRL in its
- petition (25 watts PEP for Novices, 50 watts PEP for all others)
- ''are appropriate and reasonable,'' but are not proposing Novices be
- permitted to operate at 219-220 MHz.
-
- The FCC proposed a notification system to prevent interference by
- amateur stations to stations in the Automated Maritime
- Telecommunications Systems (AMTS) and in some cases to require
- written permission from such AMTS stations.
-
- Finally, amateur operation in the 219-220 MHz band would be limited
- to 56 kilobauds and a maximum bandwidth of 100 kHz, although FCC
- requests comments on relaxing the 56-kB limit.
-
- The Comment deadline for this NPRM is June 15, 1993. The Reply
- Comment deadline is July 15, 1993. More information on this NPRM
- will appear in May QST. A detailed report on the League's filing
- appears in QST for August, 1991, page 58.
