Subject: Clear channels, do they exist?
From: rrb@deja-vu.aiss.uiuc.edu (Bill Pfeiffer)
Organization: NONE
Is there still such a thing as Clear, Regional and Local (AM) channels with
respective power limits? Used to be that on a regional channel, the
power limit was 5kw. Now I see in M-Street stations like WMCA New
York (570) and WTMJ Milwaukee (620) with CP's to go 50,000 watts days
and (like) 10,000 at night, directional. No mention of a frequency
change in these CP listings.
Now I know that FM channels are all different as to power/antenna etc,
and I know that the old power levels of 50kw, 25kw, 10kw, 5kw, 1kw,
.5kw and .25kw are a thing of the past on AM, some stations using
42watts at night, so I was just wondering are the hard limits of 5kw
on regional channels just another piece of regulatory history?

Tropoducting does indeed have directional properties... and the factor that
determines it is the shape of the dense layers in the atmosphere. If you
have two heavy, humid layers of air with a cold, dry layer between them,
the signal can be ducted as if through a waveguide. Spacing between the
layers can change efficiency and optimal frequency, and the location of
the useable waveguide structures determines where you'll be able to hear
stations from.
This morning, incidentally, the East Carolina State University station
was coming in 5/9 in Richmond, Virginia, well over a hundred miles away.
I also managed to get a few other Tidewater stations, but nothing from
further north.

All sorts of factors: tower height, the terrain profile between the
transmitter and the receiver, the power of the transmitter, the
sensitivity and selectivity of the reciever, etc. For most purposes,
though, just the transmission-related factors are considered: power,
directionality (if any), antenna height.

Bruce Elving (FM Atlas, Box 24, Adolph MN 55701) sells easy-to-use
nomographs -- i.e., coverage curves that let you quickly figure out the
radius of the transmitting area (assuming the station transmits in a
perfect circle, which few actually do, but it is a simplifying assumption).
He used to charge $4 for them.
He also prints the annual (more or less) FM Atlas, for which he already
figures out the primary coverage radius of each station in kilometers.
(That's how the FCC does it. Wonder if the FCC nurses take their
employees' temperatures in Celsius? ;-)
Others still in the business and more technically adept than I might have
other sources of info, too.

<remainder omitted>
I have heard rumors that KOPN was about to go to a commercially oriented
AAA (adult alternative-style) format, in part because of financial
difficulties.
I run the risk here of prattling on, because I am a Columbia native, and
was involved in radio there in the late 70s and early 80s, first at KCOU,
then KBIA, and finally KFRU. I was frequently a guest on some of KOPN's
public-affairs programs in my capacity as KFRU's news director.
I always thought of KOPN as a "safety valve" for constituencies that had
not reached the critical mass necessary to have their own media of expression.
When I say "critical mass," I refer to both the size of a population, and its
economic position relative to other groups in the community.
For instance, every Saturday afternoon on KOPN since I can't remember when
has been programmed by and for Columbia's African-American community.
Even though about 8-10% of Columbians are black, black Columbians had no
other voice other than KOPN's Saturday programming.
Speaking only as an observer, I think KOPN's problems have been caused by
a tendency toward infighting and a tendency toward forgetting that Columbia
is not like the rest of Central Missouri. You get five miles out of town,
and you're back in another world. KOPN tended to get isolated and not reach
out to constituencies other than those it was already serving.
Enough lecture. What are some points you can bring out in KOPN's favor?
(1) KOPN is licensed as a non-commercial educational station, in the
non-commercial educational portion of the FM band (89.5). How can a station
whose commercial enterprises are limited to underwriting announcements
effectively compete with others who have no such restrictions?
(2) The Columbia metro area is served (loosely speaking) by ten other
commercial signals and four other non-commercial signals on the FM band,
plus a "legacy" AM station. What can KOPN provide that the other stations
can't?
(3) KBXR (106.1) has just gone on the air with an adult-alternative format.
It is allied with (though not owned by) a successful, shrewd, locally owned
broadcaster. Does KOPN risk being a "me too" broadcaster (and one with
many more restrictions on commercial content and a lower-power signal)?
Moreover, KOPN will face at least two LMA's: KCMQ/KCLR and
KFRU/KARO/KBXR. Can KOPN really compete effectively in the commercial
arena?
(4) Non-commercial radio in Columbia has taken some real hits lately.
KCOU is on a restricted schedule, according to my sources. KWWC, again
according to my sources, has significant financial concerns. KBIA has
become a yupscale classical-'n-NPR operation with heavy underwriting. Are
there gaps in the non-commercial band that KOPN can pick up (especially
with the problems KCOU and KWWC suffer at the moment)?
(5) What is KOPN's purpose? Will the money that is raised with a more
commercially oriented format go to improving its niche programming? Or
will it go to more salaries and facilities?
(6) How does this affect KOPN's CPB status? Will it lose CPB money by no
longer carrying certain programs?
(7) What would Lorenzo Milam think? After all, I think you're still
using KDNA's old transmitter (KDNA was a St. Louis open-access station
that was sold by Milam (its founder) in 1973. KOPN got the transmitter.)
: Please folks, when in doubt, send,send,send. The more info the better.
Good luck. I never much cared for much of what KOPN broadcast (especially
the radical feminist crap), but I always realized that it was performing
a service to its communities.
Background for those of you not familiar with the market...
Columbia and Boone County is a metro area of 120,000 or so people.
It is just north of the state capital of Jefferson City, which is somewhat
smaller.
The five noncommercial signals in the market are KCOU (88.1, college music,
currently in political turmoil and on restricted schedule), KJLU (88.9,
Jefferson City, Lincoln University, soul music), KOPN (89.5), KWWC (90.1,
Columbia, Stephens College, jazz days, disco nights), KBIA (91.3, University
of Missouri, NPR, classical, jazz, new age, etc.).
The commercial signals are KWWR (95.7, Mexico, Mo., country and farm),
KCMQ (96.7, country), KFMZ (98.3, AOR), KCLR (99.3, country), KJMO (100.1,
Jefferson City, oldies), KARO (101.5, hot AC), KRES (104.7, Moberly, Mo.,
country and farm), KZZT (105.5, Moberly, Mo., AC), KBXR (106.1, AAA),
KTXY (106.9, Jefferson City, AOR but a change is rumored), and, on AM,
KFRU (1400, news/talk).
Columbia also "supports" two daily newspapers -- it may be the smallest
city in the country to do so. One of them is owned by a trust in conjunction
with the University of Missouri School of Journalism.
Also due to come on the air within a year are two FM signals at 93.9 and
102.3.
Doesn't sound like a fun market to try to sell time in, does it?

F-C-C To Enforce Rules Banning Indecency, But Not For Late-Night Programs
-------------------------------------------------------------------------
(Washington) -- Government regulators are returning to their
policy banning indecency on radio and t-v airwaves between 6 a-m
and 8 p-m.
The Federal Communications Commission is reducing hours for the
restriction in response to a court ruling that threw out broader
rules.
A federal appeals court upheld the government rationale that
restrictions are needed to protect children. But the court rejected
an extension of the indecency ban until midnight.
An attorney for a coalition of broadcasters that challenged the
latest regulation says the ruling should invalidate one-point-two
(M) million dollars in fines against the employer of controversial
disc jockey Howard Stern.
But F-C-C Chairman James Quello says Stern's violations occurred
between 6 a-m and 8 p-m, and thus fall under the old rule.

My father and mother moved from the NY area to Florida some
years ago. My father tells me the thing he misses most from NY
is the great radio shows in NY.
I think he would love NPR but I don't think he knows of it. Does any
one know their broadcast frequency in the West Palm Beach area of
Florida? This area of Florida also includes Port St Lucie, Palm Beach,
Jupiter, Tequesta and is due north of Boca Raton, Ft Lauderdale and Miami.
Anyone know an NPR member station in the general area?
Thanks in advance...
