A
Visit to the Camp
Shohola Communications
and Technology Center.
By
Jon Mitchell, KD3FG.
I
stopped by Camp Shohola while on a trip to the Delaware Water Gap and
the
Pocono Mountains and visited with Tom
Gibson,
WA3HWY a
fifty year
veteran of camp. I wanted to see what was new (and old)
at the Camp Shohola
Communications and Technology Center where I worked more than twenty
years ago.

I was pleased to see that after
more than 35 years of continuous summer operation, good old Wild Camp Shohola Radio
was still running! Tom has put together
an incredible program of communications and technology related
activities.
Since
1972, more than 4000 boys have learned how to operate a broadcast
console
and be a DJ at Camp Shohola. Although they now use
modern computers for production
and audio editing, they still teach tape splicing, dubbing and
multi-tracking
techniques. Camp Shohola was the first summer camp to teach radio
broadcasting
and continues with the finest and most up to date instruction
including:
play by play sports broadcasting and news gathering using remote
broadcasting
equipment, weather forecasting, announcing, console operation and
modern digital production techniques.
However, they have not forgotten the roots of
radio broadcasting and maintain
a fully operational AM broadcast facility as it would appear more than
fifty
years ago. The Collins model 12H broadcast console was
manufactured in
1936 and is a certified operating antique. It is the
oldest operating broadcast console in the world and had been
modified very little
from its construction. Some of the tubes and capacitors have
never
been replaced, and all audio transformers, potentiometers, and switches
are original. The total weight of the console exceeds 150 pounds
including
the external power supply.

There
is also a fully operational 1938 Model
15 Teletype news printer.
The wire service is set up to demonstrate how
news would be prepared in a typical radio station news room fifty years
ago. The copy is actually sent from a computer using a program that
emulates
the obsolete, five level, 67 WPM baudot code. And yes, we have four
cases
of canary yellow paper, two boxes of cotton ribbons and plenty of
replacement
springs, cams and levers for the inevitable repair. The station also
has
five broadcast cart machines, four open reel recorders, six turntables,
and 17 microphones,
some more than 50 years old. Please notice the 1930's RCA
boom
microphone stand and audio monitor enclosure in the picture on the left.
The
building is truly an operating Broadcast and
Telecommunications History Museum.
The Strowger "Step By Step" Telephone Switching
System.

Tom
started the camp wide manually operated phone system in 1974, added the
first Strowger Switching System in 1979, the electronic key system in
1983
and the computer interface in 1992. He is demonstrating how to use the
first console where phone connections were made by switching lines
together
manually by an operator, (usually the boys operating the radio
station).
All of the cabin phones are still routed through the old manual
switching
system, which remains fully operational for use during radio station
call in contests. The system has been struck many
times by Pocono Mountain electrical storms. During
one storm, "Ball Lightning", a rare natural phenomenon, formed over the
manual switching system. The blueish hissing ball was about eight
inches in
diameter and remained in the room for more than 15 seconds. It
extinguished
with a slight "POP" and left a carbon residue on the ceiling which
remains today.
In most cases the only repair need is to replace a fuse or two. The
system
is well grounded and protected by gas discharge and wire fuses. It is
rare
when it is necessary to change out a relay or other electronic
component.

The
telephone system is a fully operational Automatic Electric/Strowger
telephone
switching system invented by Almon
B. Strowger, using technology developed in the late 1890's
and early
1900's. It is similar to the one on permanent display at the American
History
Museum of the Smithsonian Institute in Washington, D.C. The switch on
the
shelf was constructed by Tom Gibson from salvaged parts of an old
1940's,
740C, AT&T switch dismantled in 1974. The switch on the floor
was constructed
in 1978 by Rick Walsh using similar components and won a first place
prize
at the Antique Telephone Collectors Convention in Hartford, Connecticut
in 1980. The single connector switch mounted on an old test stand is an
original Strowger
switch manufactured in 1908, shortly before Joseph Harris licensed the
technology
and merged the companies. The last documented repair was a capacitor
replacement 1918. The connector
is recognized by collectors as the oldest operating Strowger switch in the world.
It is being used as an intercept switch as it lacks the "G" relay to
recognize a call in progress and return the familiar
busy signal. All five switching systems are fully interconnected with
redundancy on
key components.

Here's
a closer view of the Strowger switching system constructed by
Rick Walsh in 1978 from salvaged Automatic Electric parts.
The system is completely self contained with ring generators, dial,
trunk
busy and busy tone generators, power supplies and fuse panels. There is
also a rack of eight, six volt batteries which can operate the entire
system
for up to two days in the event of a power failure, (which is not
uncommon in the
mountains). There are 109 telephone throughout the camp connected to
the
switch by more than 35 miles of paired copper wire with
over three miles buried in the rocky Pocono Mountain
ground.
There is a counter
on the system that has recorded more than 1.8 million calls on the
system
since 1979.
Thanks to the Lackawaxen Telephone Company (685 prefix with less
than 2000 subscribers), their
friendly and superb local communications service provider and one of
the few remaining 'independent telcos' in the U.S.,
the telephone
system is the only Strowger system in the
country connected
to the international telephone network and still operating in commercial service.
When family and friends telephone anyone at camp, they are
talking through the antique switch. All switching contacts are
routinely
cleaned and maintained for top operating efficiency.

The
camp system is connected to the outside world through an
old PC which records
the dialed number, duration and actual time of all outgoing calls. The
computer also routes calls to one of three different carriers for the
lowest
rates and even provides call accounting with account codes for LD
access.
All six Camp Shohola external phone lines enter through the CommTech
building where
they are processed and connected to our switching system. Incoming and
outgoing calls can be accessed from any camp phone. Some of the
features
offered include, call forwarding, conference calls and full operator
services
such as 911 emergency, 611 repair and 411 directory assistance.
Each
summer Tom prints a 10 page directory for the 280+ users of
the system. The directory even includes
a Yellow Page and a map of the camp. For more information about Tom,
his
family and his many interests, please visit Tom's
Web site.

The
Camp Shohola Amateur Radio Club, WB3DGR.
I donated a Kenwood TS-120s to the club ham
station WB3DGRto
supplement their TS-520 and Yeasu FTDX-400. The station is capable of
operating almost all band and modes with power up to two thousand watts
PEP. There are now eight radios in the shack connected to a myriad of
antennas
on the roof and in the trees. Hopefully, many campers will have their
first contacts using
this radio! WB3DGR is the first summer camp Amateur Radio station in
the
country and the only one fully licensed by the Federal Communications
Commission as an educational club.
Tom started the radio program in 1966 and received FCC licensed club
call sign,
WB3DGR in 1974. Since 1966, more than 200 boys have obtained and
amateur license through instruction at Camp Shohola including me.
Tom still teaches the International Morse Code to interested
campers even though the FCC eliminated the licensing
requirement
in early 2007. Interestingly, with the new rules, the
Advanced
Class amateur license is now the only U.S. license that documents Morse
code proficiency.
If you are on a high speed Internet connection, please view the
high resolution
video of the CommTech program. If you are on a dial
up connection, here is a
low resolution
video. There is also an .mpg
low res version.

The picture above is one of the camper cabins at Camp Shohola and is the
last one in which I was a counselor in 1985. The cabin also housed the radio
station before 1973.
