COPY OF THE PETITION:
Before the Federal Communications Commission (FCC)
Washington, DC 20554
In The Matter of
Petition to Amend Title 47 of the
Code of Federal Regulations (C.F.R.), Part 73.99
Concerning Pre-sunrise Service Authorizations
for Class D Stations in the AM Broadcast Service
PETITION FOR RULEMAKING
EXISTING RULE and PURPOSE
Part 73.99(a), (b) and (c) of the Commissions Rules and Regulations pertaining to
Pre-sunrise Service Authorization (PSRA) allow AM Standard Broadcast Class B
radio stations and Class D radio stations operating on Regional Channels the authority to
commence broadcasting at 6:00 a.m. with up to 500 watts into their daytime antenna
during months when local sunrise is after 6:00 a.m. The purpose of this rule is to
primarily provide Class D stations and Class B stations which elect to utilize PSRA
maximum uniformity in early morning operation compatible with interference
considerations. PSRA authorizes numerous AM radio stations service to their local
communities with news, weather and other important information commencing at
6:00 a.m. throughout the year, irregardless of actual time of local sunrise.
The majority of radio, television and cable broadcast media typically initiate their
"morning drive" programing at 5:00 a.m. and continue through to 9:00 a.m. local time.
The 5:00 a.m. first hour "morning drive" programming is geared to a significant portion
of the public that start their day prior to 6:00 a.m. due to extended commuting times
and / or early occupational clock-in requirements.
Class D and Class B AM radio stations that elect to utilize (PSRA) must wait until sunrise or
6:00 a.m. to initiate operation with up to 500 watts under Pre-sunrise Authority as
outlined in Part 73.99 of the Rules. Prior to 6:00 a.m. or local sunrise, whichever is
earlier, Class D AM radio stations must remain either silent or operate under nighttime
authorization at substandard power levels, typically between 1 and 100 watts. Class B
radio stations which utilize PSRA must also wait until 6:00 a.m. to initiate PSRA service and
utilize their less restrictive daytime antennas patterns with 500 watts. Restricting PSRA
commencement until after 6:00 a.m. restricts service from AM broadcast radio stations, a
disproportionate number which serve smaller communities with limited local radio
choices. For example, an individual waking up to a clock radio at 5:30 a.m. would
unlikely set the clock radio to a Class D AM station because of the off-air status or
substandard power prior to 6:00 a.m., making reception difficult or non-existent. This
problem is magnified with consideration that "morning drive" is the most important time
slot for many radio stations, the time when radio listenership is maximized and of greatest
importance and service to the general public.
This Petition requests that the Commission authorize AM radio stations to provide
complete service during the "morning drive" time slot under PSRA commencing one hour earlier at
5:00 a.m. local time instead of the current 6:00 a.m. restriction. This will expand the
"morning drive" programming of many AM radio stations to match existing FM radio,
television and cable programmers, something which is overdue.
The Petitioner requests that the Federal Communications Commission amend Title 47, Code of Federal
Regulations, Part 73.99 of the Rules to authorize
Pre-sunrise Authority (PSRA) commencing one hour earlier at 5:00 a.m. local time for all radio stations
operating on Regional Channels. A copy of the proposed revision to Title 47 C.F.R., Part 73.99 is
attached. For clarity, under the Rules, AM radio stations are NOT required to participate in PSRA
and could elect to abstain or to commence PSRA operation after 5:00 a.m.
International negotiations, if any, should be minimal with regard to this matter as only
stations operating on Regional Channels are addressed and NO foreign Class A
Stations are affected. Also, NO domestic Class A AM radio stations are affected by this matter.
Class D stations on frequencies shared with Class A radio stations have purposely been
omitted from this Petition as I believe they involve more difficult International
negotiations, associated time restraints and/or additional domestic interference
concerns, but nonetheless, the Commission could consider Class D stations operating
on frequencies shared with Class A stations in whole or part either now or at a
later date. Addressing Regional Channel stations first will facilitate action on this matter.
I believe that this Petition serves the public interest in that it further facilitates better
distribution of the broadcast spectrum, particularly to smaller communities where local
radio service is generally limited and frequently served by AM stations supporting the
Federal Communications Commission's bedrock goals of localism, competition and
diversity in the broadcast media.
I further believe that service gains to all Class D and to some Class B radio stations on
Regional Channels will be significant and that negative impact to co-channel stations
will be negligible in that this Petition simply requests of one additional hour of Pre-
sunrise Authority only on Regional Channels. Pre-sunrise Authority has withstood the
test of time and has proven to help serve the public need and necessity dating back to
1967. Amending Title 47 of the Code of Federal Regulations (C.F.R.), Part 73.99 of
the Rules as requested herein will further this cause.
I believe this Petition is worthy of Commission consideration in light of the fact that AM
stations tend to program community responsive formats including foreign language,
news, talk, sports and religion traditionally and frequently all with heavy local emphasis.

FCC AM Standard Broadcast Facility Statistics as of February 20, 2010:
Total number of licensed AM facilities (all Classes)...............................................: 4863
Total number of licensed Class B (full-time) and Class D (daytime) AM facilities
on Regional Channels (less expanded band facilities on 1610 to 1700 kHz ##)...: 2063 #
Total number of licensed Class D (daytime) AM facilities on All AM Channels......: 1930
Total number of licensed Class D (daytime) AM facilities on Regional Channels
(less expanded band facilities on 1610 to 1700 kHz ##)......................................: 911 *
Total number of licensed Class B (full-time) AM facilities on Regional Channels
(less expanded band facilities on 1610 to 1700 kHz ##)......................................: 1152 **
Total number of licensed facilities NOT on Regional Channels
and therefore NOT affected by this Petition as filed:............................................: 2800
* A total of 911 Class D (daytime) FCC authorized AM facilities on Regional Channels will benefit by amendment of Part 73.99 of the Rules
as requested herein. These 911 facilities represent 18.7% of the total number of 4863 AM Standard Broadcast facilities.
** Part of 1152 Class B FCC licensed AM facilities on Regional Channels will also benefit by amendment of Part 73.99 of the Rules as
requested herein. These facilities that operate with less than 500 watts nighttime or operate with higher night power but with an undesirable
nighttime antenna pattern are potential beneficiaries under this Petition. Class B facilities on Regional Channels with STA's for their nighttime
antenna and/or emergency condition when normal nighttime antenna system is inoperative are potential beneficiaries. There are 1152 Class B
facilities on Regional Channels (excluding the extended band) which represent 23.7% of the total number of 4863 FCC authorized AM broadcasters.
# The combined total of all Class B and class D FCC authorized facilities on Regional Channels from 550Khz to 1600 kHz inclusive represents 42.4%
of all AM facilities.
## Facilities operating in the extended band (1610 kHz to 1700 kHz inclusive) will NOT be affected by this proposal based on analysis
of existing stations.
