Subject: DC Kids Radio, etc.
From: Robert Carpenter <[e-mail]>
Organization: National Institute of Standards and Technology (NIST)

Moderator Bill has posted (cocerning the Kids Radio station in Manassas, VA):

The station site SW of Manassas is 27 miles SW of the Washington Monument, by
my measure. They are on the far SW edge of the densest population, though
some suburbs lie farther out. The 1460 in Manassas had been off the air for a
number of years. Out here in Rockville, MD (the NW suburbs of DC), I am also
about 27 miles from their site. They are reasonably interference-free
starting 1.5 to 2 hours after sunrise until a couple of hours before sunset;
not very long in winter.  But the Manassas Kids Radio station DOESN'T NEED
good coverage over DC and the Maryland suburbs during the day since their
1050 kHz Silver Spring daytimer does just fine.

I'm only 8 miles from WWDC, 1260 kHz 5 kW day and night, and they suffer
interference almost as much of the time...but not as bad. Clearly I'm in a
deep null of WWDC-AM. In parts of Rockville you can see WTOP's towers, yet
have trouble hearing them when they are on their night-time pattern.

I contend that (one of) the main reason(s)  for AM's troubles lie(s) in the
fact that much of the big cities's expansion has been outside their solid
coverage area - especially true at drive-time in the winter.  The NIMBY and
environmental-impact business means that most stations can't move, even if
they would still have enough sig in their city-of-license.  I know that WTOP
(1500 kHz 50 kW) tried to move near me a couple of decades ago. The neighbors
stopped it, though the site near a large quarry probably wasn't so great at
that.  Then 'TOP tried to move into the Potomac River valley near Cabin John
(just outside the Beltway). The neighbors there got the Navy's Ship Research
& Dev facility nearby to say it would interfere with their instruments. 'TOP
has trouble covering downtown DC at night at the present and can't go farther
out.

WTEM-AM (570kHz 5kW day/1kW night) has built a facility WAY out at Germantown,
but were not using it as of a few months ago. It is about 13 miles from the
center of Bethesda (city-of-license) and 19 miles from the Washington
Monument; about 9 miles farther out than their old site. Has it been neighbor
trouble or inadequate coverage at night???

Enough...

From: [e-mail] (Dan Bammes)
Organization: University of Utah Computer Center, Salt Lake City, Ut.

    If you want to get good reception on the AM band, there's nothing like
a REALLY LONG wire to get the job done.  If you can run it on the roof of
an apartment building or under the eaves of your house, you'll do even
better.  Next, hook up a ground connection to the ground bus on your radio's
 circuit board.  Tie it to a metal stake and pound it into the ground.

    Good idea to have a lightning arrestor, too -- you can get those at
Radio Shack.

[Moderator's Note:  While a long wire is good, it doesn't offer any
directionality, which comes in very handy while DXing.  Somewhere in
the archives is an article on constructing a large framed loop, which
the author claimed was very directional.  I would not be without a
directional AM receive antenna for DX.  Bill]

Beware of cheap carts. Call each manufacturer (check with the buyer's
guide issue from any broadcast or brodcast engineering issue) and ask for
a sample.

Please note:
       to work correctly in a cart machine your carts should be in
        good condition.
    ideally you should use only one type of cart in the station
        (they will work best if the cart machines are aligned
        to one type of cart)
    cheap carts generally have cheap tape, which will age quickly
        and may not be suitable for stereo cart machines.
    a simple cart mechanism (brakes and the like) will make reloading
        carts easy.
    there are firms which will reload and recondition old carts.

Call the CRTC in Halifax, they will give you the most up to date

As far as I know there are no regulations which restrict religious
broadcasting as such, but every station must follow the CRTC general
regulations (balance, music content, Canadian content, programming formats
etc.).

Not that I know of. He worked for years and years as a CBS correspondent
covering various D.C. beats, and has had a distinguished career as a foreign
correspondent for CBS in Moscow and in several eastern European countries.
AFter leaving CBS, he worked for the then brand new CNN for a year or so
before signing on as a analyst with NPR.  Why do you ask?

The first "duopoly" in the Detroit radio market was recently
announced. Greater Media, owners of Classic Rock WCSX 94.7 FM
and "Honey Radio" WHND 560 AM have announced intention to purchase
WRIF 101.1 FM, an AOR owned by Great American Broadcasting.
WRIF, formerly WXYZ-FM was at one time an ABC o-and-o, prior to
the CapCities buyout.

    I've build subcarrier generators (direct FM at subcarrier
frequency) and subcarrier demodulators (wideband hetrodyne up to 455 KHz
where it is filtered and demodulated using a ceramic filter and ceramic
FM demod).  These are used to provide a voice grade circuit where we
then run 1200 bps FSK (using Bell 202 tones) and occasional voice.  I'm
now thinking of making some "frequency shifters" to hetrodyne standard
2400 bps QAM (or higher speed dial-up modems) up to FM subcarrier (26
KHz to 92 KHz) or video subcarrier (4.5 MHz up to 10 MHz for use on
microwave systems).  This "frequency shift" approach would allow low
cost mass market modems to be used to generate and demodulate the
signals, then just shift them to where we have spectrum available.
    So far it's just a thought.  Any comments?

Subject: Digital Audio Delivery
From: [e-mail] (Bill Raffel)
Organization: University at Buffalo

The radio station I work at recently went through a major technology change.
We have scrapped carts for Digital Audio Delivery.  WNED-AM & FM in Buffalo
recently moved into a new building, along with the public TV stations.  We
have brand new studios complete with DAT machines and computers.  When we
put stories together now, the computer does the recording and the editing.

The computers in the control rooms have touch screens, so when you want to
play a cut, you just hit the appropriate "button" on the screen, and it plays.
To save money, you operate the computers in the production studios with a
mouse, but the screen displays look the same.

The screens have a left side and a right side.  You can set it up so the left
side records, while the right side plays back.  Each side has a separate input
on the board.  If you want to record a news "wrap", you would set up the machine
so it would play back your sound bite from the right side.  You would start the
recording on the left side, but you don't have to start talking immediately.
When the time comes for the sound bite, you would tell the right side of the
screen to start playing.  When you're finished, you can edit the recording.
You can simply tell the machine where to start and stop the playback, or you
can actually cut and paste material.  The machine will print out audio in
bursts that look something like this:  ||||||||||-------|||||||||||||.  The
longer the line, the higher the level of the sound.  Pauses look like the
dashed line.  To edit, you would move the beginning cursor and the ending
cursors to highlight appropriate areas.

There are a couple drawbacks to the system.  If you have a problem with a cart,
you can pretty much figure out why - dropouts, dirty heads, etc.  With the
computer, mistakes are much harder to pinpoint.  The cuts are stored by number
in the computer.  It is easy to load the wrong number by mistake.  With a cart
sitting on top of copy, that was easier to avoid.  Lastly, all terminals
are connected together.  It is possible for someone to erase a cut in one
room, that someone is about to play on the air.  The person in the on-air studio
would not know, until the cut doesn't play for some strange reason.

The sound quality is very good, but it has been scary going through the first
major technology change since I've been in broadcasting.

If you are posting to this group....you very probably can
send e-mail as well. If you know what their address is...it
should be no problem to do so. I think I heard Mike say that
they had a Compuserve account. If that is the case...the
internet gateways into Compuserve very easily.

If you can find out where or what they are on...we will help
you to get there.

Don&Mike newsgroup...hmmmmm. Maybe if they stretch out to a
few more cities we'll have enough people to get one going.
I'm not sure whether we have 100 Don&Mike listeners with
Internet access at present.

I played football with the two of them in a charity game against the Redskins,
and I can attest to the fact that they are just the same off the air as they
are on the air--just a couple of grown up kids.  The game was a blast, it was
broadcast on the air by a local sportscaster, making us feel like we were
"in a real game."  (Note:  The Redskins didn't play at half speed like they
said, but it was still fun)

I'm all up for a D&M newsgroup, but I wonder if there are that many folks out
there who listen.  Time will tell.

Buh-bye!
