One day in 1915,
after reading a 10¢ booklet* about the wonders of a new invention called
"Wireless," a 16 year old boy named Elmer G. Osterhoudt
began the construction of a crystal radio. He was attempting to receive the signals that were said to be invisibly
traveling through space, undetectable by human senses.
He wound a beautiful coil made of 200 turns of 28 gauge
cotton covered wire on a
piece of broom handle. Then he painted it with white lead paint
which he had invented himself.
Connecting the coil to a crystal, headphones and antenna, he
listened in vain for the wireless signals. He soon came to
the realization that his radio didn't work. The lead in the
paint had ruined the coil. The radio was stone dead; he
couldn't get as much as a click out of the headphones.
Elmer had a neighbor who was also interested in Wireless and who was
also named Elmer. This Elmer also had made a radio that didn't
work. He came by with his radio because Elmer Osterhoudt
"knew all about radio." Elmer put the other Elmer's non-painted coil
into his set and in came a powerful rotary spark signal from
station 6JG!
The magic of this single event influenced
the entire remainder of his life. An original account can be
found on Page 2 of "How To Make Coils" by Elmer Osterhoudt.
* In HB-5 "CRYSTAL SET
CONSTRUCTION" Elmer writes that the magazine was "The
Electrical Experimenter." In April of 1915 the price of this
magazine went from 5¢ to 10¢. The July issue, on page 109,
shows a simple wireless receiving set. There is no coil
data, but the illustration resembles what Elmer described
above. Page 109 also has an article on how to blow up a toy
boat using homemade wireless apparatus and a simple mine
filled with gun powder.

MRL Mystery: (The first of several to be
found on this site). In 1917 Elmer Osterhoudt and his family lived at this
address at 1936 East 77th Ave in Los Angeles, CA. The 100+
year old house, built in 1908, lies under the additions and
modern exterior of this building. Did Elmer
live here two years prior, in 1915? Is this the site where
he and the "other" Elmer made his first radio?
Elmer wrote that in
1917, while living at 77th and Crockett (the house in the
photo above), he had erected a 55
foot antenna mast made of all sorts of 2x4s, 2x3s
and pairs of 1x2s. It had a dozen guy wires made of
bailing wire. On top of the mast was a four wire
antenna, each wire separated by 30 inches. (He didn't say
what the other end was connected to.) It was up for about a year
when his father decided to move, so he had to take it down.
That's when he noticed the bailing wire had almost rusted
through. It would have fallen down by itself in another
month, and would have either hit the house or have fallen
into the street!
If that was the case, we're probably looking at the exact
spot where the mast was located.

During his lifetime Elmer Osterhoudt would (in all
probability) hand-wind more coils and build more crystal
radios than anyone who has ever lived. He outlasted all his
competitors in the mail order crystal
radio business. He, along with his wife Mabel, ran a mail order company
named "Modern Radio Laboratories" for 55 years.
He
sold thousands of kits, coils, crystals and all parts
related to crystal radios, many of
which he made himself. He published the MRL catalog and wrote many handbooks, "Detail
Prints" and a quarterly magazine called "Radio Builder
and Hobbyist." He printed them himself, at first with a
mimeograph machine and later
on a lithograph
printer.
Everything needed for a radio could be found in his catalog;
coils, capacitors, headphones, switches, jacks, binding posts,
sockets, crystal stands, knobs, batteries, wire, all sorts of hardware and
even vacuum tubes and transistors. He manufactured over
FIFTY-FIVE
types of plug-in and solenoid coils, all made by hand!

There is very little information about
Elmer available but we
can glean some details from his literature - and there was a
LOT of it. He also included a hand written note with each
order, some of which have survived.
His company, Modern Radio Laboratories,
was established in 1932. It says so, right at the top of the
"EXPERIMENTER'S CATALOG." Oddly enough, Elmer rarely used
the entire name in his handbooks and other literature.
Even on the catalog it is shortened to "MODERN RADIO LABS"
and elsewhere simply to "MRL." Some of his
magazine advertisements listed the company as "Modern Radiolabs" but later
it was shortened to
"Laboratories," since these ads were charged by the
number of words.
Every one of his handbooks has this list of accomplishments
printed inside the front cover: |

Elmer was
born in Scotts Mills, Oregon on October 6, 1899, the
son of Wilbert and Minnie Osterhoudt. Wilbert (also
known as William) was a carpenter. Elmer had a
brother named Cyril, who was born on April 17, 1901.
Tragically, their mother died in 1903 at the age of
27.
Note: To be precise, Elmer was born in Butte Creek, Oregon.
Butte Creek was incorporated into Scotts Mills in
1916. He was apparently born on a farm and not in
the town of Scotts Mills itself.
On August 30, 1914, eleven years after the death of
Minnie, his father married Alice Elsie Shields . Elmer soon had six additional half-brothers
and sisters, though two sisters died young; one
lived to be two years old and the other, four. (See
page ten.)
The Osterhoudt family moved to Los Angeles,
California sometime in 1915. The Los Angeles
1916 Long Beach City directory lists,
"Osterhoudt W A woodwkr Jones Sash and Door
Company." The "W A" would be William
Arthur.
With the exception of two brief moves
to Reno, Nevada in 1950 and 1971, Elmer spent the
rest of his life in California. He and all of his
siblings are buried in the Los Angeles area. Other
than the
story of making the crystal radio in 1915, we know
little else of his youth. Handbook 8, "Radio Kinks
and Quips," contains the following three sentences:
"At home, my brother and I used to drive our
poor Dad
nuts. We had an Edison Cylinder record phonograph.
We used to reverse the belt and run it backwards."
That's about all we know, but it gives some insight
into Elmer's personality. |

In 1918
Elmer worked as a laborer at Southern Board and
Paper Mills, now known as PABCO. This building was
built in 1912 and would have been quite new when
Elmer was employed there. Located at 4460 Pacific
Blvd, the area was known as Vernon at
the time, but is now Los Angeles. 100 years later
the building is still there making paper products.
Presently, this
building is one corner of a huge complex of buildings, some
of them very dilapidated.
At the time, Elmer and his family lived at 8011
Crockett Blvd in Los Angeles. Southern Board and
Paper Mills was a little less than a mile from their
house. |

On September 12, 1918 there was a U.S. Military
draft registration (the 3rd one of the war) for men
aged 18 through 45. Prior to this third draft, the
minimum age was 21. Elmer would have fallen into the new category.
He registered on the very day the new draft went
into effect, Sept 12, 1918. He was stationed at
the Alameda U.S. Naval Base. The war was over "at the 11th hour on the 11th day of
the 11th month of 1918."
Draft Card
According to Elmer, he attained the
title "Radio Mechanic, Maximum" while in the Navy.
Escaping both
the war and
the 1918 Spanish Flu pandemic with his life, he was
20 years old when he got his Amateur Radio license
in 1919.
1919 was the age of the spark gap transmitter.
Elmer's first transmitter was a spark plug coil from
a Ford automobile that was fed with an AC doorbell
transformer. The tone changed during transmission as
the points got hot! His second transmitter, which he
called his "handsome homemade rotary spark," was fed
with a 1/2 kilowatt transformer from Sears and
Roebuck. At the first press of the key the spark
jumped to the shaft of the motor. One can imagine
the look on his face as the rapidly spinning motor
shaft slowly came to a
stop - permanently. Later he "got a new rotary
spark gap" and "proceeded to jam up the air."
The "Pacific Radio News" issue of May 10, 1920 lists
Elmer as holding the radio call letters 6NW. They
spelled his name wrong. The "Citizen's Radio Call
Book" of November 1922 spelled it worse - "Ousterbouat."
 |
How did
Elmer fund his radio research and experiments?
According to the preface in his handbooks, he was
a technician at Electrical Products Company.
This was a company in Los Angeles, founded in 1912,
that made electric and neon signs. Elmer wrote that
he worked there "during the war," so this would have
been sometime after 1914 but before he began his
stint with the Navy in 1918.
There is an entry in the Los Angeles 1920 City
Directory showing an E. G. Osterhoudt working at
Hammond Lumber Company. This isn't as far-fetched as
it seems. Both his father and his Uncle John (who
lived in the same house with Elmer) were carpenters,
and would probably know if a job became available at
a lumber yard.
As for his roles
at Majestic Electrical Products and U. S. Motor
Company, Elmer never mentioned these in his
writings, nor did he ever mention working in a
lumber or paper mill.
Likewise, he never mentioned that in 1920 he was a
member of the California Academy of Sciences.
In June of 1920, he traveled to San Francisco hoping
to land a job as a radio operator aboard a ship. He
arrived on a Saturday. By Sunday he was down to his
last $20. By Monday was employed at Southern California Edison Company
as a wireless operator, a fact the 1920 US Census
verifies. That job didn't seem to suit
him, and later in 1920 he finally obtained a job aboard
a ship.
From 1920 to 1923
he was at sea as a radio operator. He made $225 a
month, which he said was "good money." According to
Elmer, in 1921 he worked aboard the "El Segundo" (an
oil tanker built in 1912 and owned by Standard Oil). In
1921 there was some sort of strike, which backfired.
The radio operators lost $20 a month, and Elmer
ended up on a lumber scow named the "Williamette."
Apparently, life aboard the Williamette wasn't very
pleasant due to the light ship lurching in the waves. Elmer wrote that he got six meals a day;
"three down and three up." A good part of
his time was spent "hanging over the rail."
Elmer also worked in the radio room of the SS Atlas
in 1921 and 1922. He then served
aboard a steam ship named the J. A. Moffett, owned
by Standard Oil of California. The transmitter
aboard the J. A. Moffett was a Marconi P-4.
Though the J. A, Moffett was owned by Standard Oil ,
Elmer actually worked for RCA. Elmer wrote that in the
1920s he reported to a Chief Radio Operator named
Dick Johnson, who worked for RCA. On the next page
is a letter Elmer signed aboard the ship, "care
of Radio Corporation of America."
Elmer wrote that he "quit" in 1923. By then, almost
every other ship on the Pacific coast was a Japanese
cargo ship.
Apparently, he studied Pharmacy for two years during
his time at sea. In Elmer's own vague words, "Read
up on Pharmacy for 2 yrs. with phones on."
He attended one semester of USC College of Pharmacy
in Los Angeles. Afterwards he became "official janitor" in a drug
store, and entertained the idea of owning his own
drug store. His ham shack sat on a property he
owned. In Elmer's own words, "I had a lot with my
6NW on the back." He sold the lot for $1000. With
that and the money he saved while at sea (he called
it Ship money), he opened a store. Thankfully, it wasn't a drug store.
In 1924 he opened the "Manchester Radio Electric
Shop" on Manchester Avenue in Los Angeles, California. He worked in
the store from 9AM till 9PM six days a week, and a
half day on Sunday. According to Elmer, (Radio Notes
No.1, page 16) he made hundreds of Harkness Reflex
sets. The Harkness sets came in kit form. Elmer
added a power supply, batteries, a cabinet and a
speaker, and sold them for $65. He was also a dealer
of Stewart-Warner and Majestic brand radios. The Harkness radio
can be found page 13 of the November 1923 issue
Radio Broadcast.

In various issues of "Radio News" (not the same as
"Pacific Radio News") it was reported that Elmer's
call sign of 6NW was heard in Fort Wayne, Indiana
(April, 1925), Hayaitai, New Zealand (February,
1926), East Orange, New Jersey (July, 1926), Berwyn,
Illinois (October, 1926), and Amuay, Venezuela (June,
1928).
Early issues of QST magazine reported 6NW was heard
in Cleveland, Ohio (January, 1925), Panama Canal
(January, 1926), Smethwick, England (July 1926), New
York City (March, 1927), Hyogoken, Japan (June
1927), Hanscom, Alaska (December 1927), Saranac,
Michigan (December, 1927), and others too numerous
to mention, even a submarine docked at a port in
Honolulu, Hawaii.
|
Elmer wrote that the Amateur Radio guys wanted him
to set up a station in his shop, but he refused
because the shop would always be full of loiterers
and no work would get done. He said that calling "CQ"
far into the night would be a waste of time that
could be put to other uses. "Running a radio shop
took all your time if you wanted to stay in
business." He must have found this out the hard
way, because Elmer made the "Brass Pounders League" in the
March 1926 issue of QST with 117 contacts.
In 1928 Elmer moved to Oakland, California and
opened a shop on 14th Street. On October 7, 1929 he
married Mabel
Elizabeth Smith, and they moved into a house at
2125 East 28th Street, in Oakland.
Two weeks later the stock market crashed, followed
by the Great Depression. In 1930, business got so
bad he
decided to go back to sea. When he tried to get a job
on a ship, the Chief Radio Operator laughed. There
were 150 guys on a list waiting for the same job.
Instead of going out to sea, he kept the radio shop
open, but apparently moved it from 14th Street to
23rd Avenue. In 1932 Elmer "invented" the celluloid
plug-in coil and the No.1 and No.2 crystal sets. He and Mabel
then began Modern Radio Laboratories.
The trademarks for MRL and Modern Radio
Laboratories were registered on December 15, 1932.

In 1924 Elmer's radio store, the
Manchester Radio Electric Shop, was located at 1522
Manchester Avenue in Los Angeles.
Manchester Avenue was renamed East Firestone Boulevard
around
1927. The city directories for the Watts-Compton area of
California show the store was there till 1928. As stated above, Elmer moved to Oakland in 1928. |

MRL Mystery: From
1924 to 1928 Elmer's radio store was in Los Angeles,
CA. In 1928 he moved to Oakland CA. In 1929 he
married Mabel Smith, but Mabel was from San
Francisco. San Francisco isn't far from Oakland, but
the San Francisco-Oakland Bay Bridge wasn't built
till 1936! How did they meet? |

_____________________________________________________

Modern
Radio Laboratories was a mail order company. You
mailed your order to MRL and Elmer sent the order
through the US mail back to you. Most of the MRL
advertising consisted of sometimes vague three or four line
advertisements in radio magazines. His "business plan" was
brilliant and will be explained on Page 6.
Long after the crystal radio was
eclipsed by the regen radio, then the TRF receiver
and finally the Superheterodyne, Elmer Osterhoudt
via MRL continued to sell radio parts and plans to
crystal set "fans" who made their own radios.
According to Elmer, the "golden age" of the crystal
radio ended in 1924. As time marched on and
many parts became commercially unavailable, he made them
himself.
Of paramount importance to him was keeping the cost
down for the experimenters who bought from MRL.
Elmer spent 54 years making radio parts by hand. He may
have been an artisan, but he wasn't
was an artist in the ink on paper sense of the word.
He admitted his hand writing was awful. There are hundreds of drawings in his
catalogs and handbooks but unless you know what the
parts look like, the drawings are hard to fathom. On
the rest of this site we'll compare some actual MRL parts with the drawings.
This is not to criticize Elmer's drawing skills. If
he had taken a drawing class perhaps his catalog and
handbooks wouldn't possess the uniqueness they do.
Instead, the goal is
to show what a fine product you got compared to the
drawing of the same product in the catalog. Those of us still
alive who purchased from MRL will see what they were
actually looking at in the catalog. Unfortunately,
most of the 10,000 MRL customers have already passed away,
along with Elmer and Mabel.

Welcome back! Did you
see that guy on Page A-5? For years I wondered if
that was Elmer. Why would EO have a picture of some
random guy in the catalog? It's NOT him. It's a
radio operator at a police station. Elmer took the
picture from a National Radio Institute publication. |
|
|
|
|
His name
was Donald H. Peters of Findlay, Ohio.
LINK
|
Here's another MRL mystery: Did
Elmer take a course in radio repair?
Only NRI graduates
received National Radio-TV News. Where did he get his copy?
The entry in the catalog advertises HB-11, "Radio
Operating as a Career." It was copyrighted in 1961,
but this photo is from 1951. The photo appears on
page 5 of the handbook. |
|
|
This is
the only picture of a human being in all of Elmer's
surviving library of literature. Why did Elmer
choose this picture? Did Donald Peters resemble
Elmer? According to his 1942 draft card, Elmer was 5' 10" tall, weighed 195 pounds, and
had a light complexion with blonde hair and blue
eyes. (His 1918 draft card stated he had light brown
hair.) The ship manifest from the J. A. Moffett,
dated January 28, 1922 states he weighed 175 pounds,
so he gained 20 pounds in 20 years!
In one of his publications Elmer stated that
he might include a photo of Mabel and himself in a
future edition. Whether he did or not is one more
MRL mystery. |
