COMMUNICATIONS
. . .
Jamaica.
We've been hearing JBC
Ra-
dio One on
a new
frequency of 850
kHz
during
hours of
darkness. Ron Schatz
says
channel
1 is registered
for a relay at
Old Harbour,
southwest of
Kingston.
Nicaragua. This country
has become
rather paranoid about
"intrusion"
of
foreign broadcasts,
something
which is
actually completely
natural
and un-
avoidable
in
a
small country
next to
others.
On an
anti -communist
TV pro-
gram in Miami,
former Nicaraguan
gov-
ernment
communications
minister
Mario
Cordero
charged
that the Sandinstas
are
setting
up to
two powerful
new transmit-
ters of
their own,
one about
100
km
northwest
of
Managua, and the
other
in
a
remote coastal area
lacking
roads
near
Puerto Cabezas
on the Caribbean.
We
assume
these
will
be
mediumwave.
Saba.
There has been a radio station
on
this
Netherlands
Antille for a year or two,
which has
escaped
official
notice, but has
been heard by
visitors to nearby St.
Maarten, such
as
John
Schmid -it's
Voice
of Saba,
on 1410 kHz.
St. Kitts. Another
small Caribbean
island is
well -known among
medium -
wave DXers, thanks
to the powerful
Radio Paradise,
835 kHz, another
U.S. -
backed gospel outlet.
But
now it's made
short
waves too,
due to a third
harmonic
on
2475 kHz, heard during
the evening
hours by Bob
Hill in Massachusetts.
San
Andres. This Colombian
island off
Nicaragua amounts
to a separate
radio
country
well -known to
hams, but
not to
mediumwave
and shortwave
DX
listen-
ers, since
its radio stations
are usually
mixed in with Colombian
mainlanders.

named after the

might
when

enjoyment.
But
in
the business
and educational
world of
reading,
this
is
not generally
necessary.
And that's
where
speed
reading
comes
in.
A key consideration
in this
training
pro-
gram
is learning
not to
read every
word.
If
you do, you'll
limit yourself
to a
fraction
of
your reading
speed potential.
Instead,
reading
in
"idea
clusters"
is the core
of the
training
presented
in MicroSpeedRead.
The program
operated
flawlessly,
though
I
wish that one
could
press `Escape"
in the
middle of sections
should one
wish
to
quit
a part
and
move swiftly
to another.
But
since
I'm talking
about
only seconds
of
time
perhaps
wasted, this
is really
a minor
criticism.
MicroSpeedRead
is
a
most useful
com-
puter
program
for anyone
who would
like
to
improve
his
reading productivity.
Average
reading speed
is 250
words per
minute,
by the
way,
while
500
wpm is con-
sidered
to
be only
"good."

ond
harmonic of 1261.4
(nominal 1260

We found
it
fascinating
listening, with
its mixture
of
Spanish
and Caribbean
English. Also on
the air
from the island is
Radio
San
An-
dres, 910
kHz, seldom heard
in the USA;
but
we picked it up during
the daytime on

Sweden.
After decades as
a Tuesday
fixture,
"Sweden
Calling
DXers" moved
to
Wednesday on Radio Sweden
Inter-
national. Complicating
the picture
was
an advanced start
to the next UTC
day's
programming, so that
it
appears
on the
2300
UTC
Tuesday, and
1400
UTC
Wed-
nesday
broadcasts,
the
latter on 15345.

U.S.A.
KCBI,
Dallas, has added
"World of Radio" to
its schedule,
Fri-
days at
2100 UTC on
11790, and Sundays
1830
on 11905.
WHRI, Noblesville, Indiana,
went
on
the air toward
the end of last year.
After
several frequency changes
to avoid
inter-
ference, this schedule
emerged:
1100
-1300 on 5995,
1300 -1500 on
11850,
1500
-1700 on
15105,
1700 -1900
on
15355, 1900 -2100 on
11865, 2100 -2300
on 9770,
2300 -0100 on 11775,
0100 -0300
on 9745, 0300 -0600
on 7400, 0600 -0800
on 6100,
0800 -1100 on
7355. Part of
these are directed
northeast, part
directed to the southeast.
There may
have
been
further
changes
in March.
Radio Earth quickly
moved from
KCBI to
WHRI, where it could broad-
cast
at its preferred prime
time, 10 pm
EST (0300 UTC year-
round), six nights
a
week,
on
7400 kHz.
KVOH, Simi
Valley, California, ex-
perienced
delays in transmitter delivery,
but hoped to start
testing by early
March. NDXE, Opelika,
Alabama, con-
tinues
a major advertising
campaign
without
any transmitters
and continual
target
date delays; they've
been predict-
ing July 4, 1986.
Meanwhile, the FCC
points out
that they do
not plan to au-
thorize such
an N -prefix callsign
for a
broadcasting
sation.
This won't neces-
sarily
keep the station
from going
by
those
letters -the call
letters just
won't
be official.
