Telegraph history books

Do you know the book "The History of Telegraphy" van Kenneth Beauchamp ?

Peter PA0RLM



The RMSL has several railroad and telegraphy books listed on eBay........

that are surplus to the collection and therefore de-accessioned.

All proceeds go toward Boyce railway depot repairs, utility, and maintenance expenses..

Thank you and best wishes, 
In the 1913 former N&W Railway depot along Clarke County route 723 117 East Main Street Boyce, VA 22620-9369

"The Brasspounder" by D. G. Sanders.

Quite some years ago I acquired a copy of the book, "The Brasspounder" by D. G. Sanders at a used book store.

I still sometimes see copies at such places.

However, both new and used copies are available from Amazon including a Kindle download.

It is by far the best "slice of life" telegrapher autobiography I have ever read.

I reviewed this some years ago in my book and movie review column in D&D. (Dots & Dasches)

If you haven't already read this book I can strongly recommend it.

Here's the link:

Richard Spilman Culley, an Englishman, published "Handbook of Practical Telegraphy," ............

which went through four editions between 1867 and 1870.

I have found the 4th (1870) edition on Google Books.

 Anyone know where the first (1867) edition may be found?

Hi Abe,

How about an edition by this same author from 1863:

David Homer Bates, 1913 Article

David Homer Bates (1843-1926) is something of an enigma.

He was one of the four original members of the U.S. Military Telegraph Corps and was White House Telegrapher for Lincoln during the Civil War.

He published Lincoln in the Telegraph Office in 1907, and his own memoirs shortly thereafter.

    There appear to be no good biography of Bates, only scattered paragraphs published in various places, and I cannot find his obituary (he died in NY City and is buried in Philadelphia.)

In 1884, he became President of the Baltimore & Ohio Telegraph Co.

One source cryptically says, "Western Union took over the B&O Telegraph, and that ended Mr. Bates' telegraph career." Was there more to that story...?
    After leaving the B&O Telegraph, he worked for Gamewell Fire Alarm Telegraph, and then "Bradstreet Company," which was possibly one of the antecedents of today's Dun & Bradstreet.

    I have uploaded to the List's Files section an article lifted from the 1913 Electrical Review. (The uploaded file is titled Bates, David Homer - Electrical Review 1913.)

The article carries a photo of David Homer Bates with Gen. Thomas T. Eckert, head of the Military Telegraph Corps, and two other old time telegraphers. However, the magazine caption wrongly identifies Bates in the photograph, so I added a note at the top of the file correcting the error.

    Hopefully someone with a subscription to or the NY Times files can pull up an obituary of this apparently quiet but interesting man.

I should have included exact dates for D.H.B., in case anyone is inspired to do some looking around.

Born 7-3-1843 Steubenville, Ohio. Died 6-15-1926, New York City.

"The Telegraph Goes to War"

One book you might want to check is "The Telegraph Goes to War" edited by Donald E. Markle (ISBN-1-889246-54-9) published in 2003.

It consists of excerpts from Bates' diary he kept during the Civil War.

I reviewed it in D&D in the fall 2011 issue.

Compared to the O'Brien book which is a field telegraphers view of the war, this is a view from Washington as Bates worked in the War Department telegraph office, a completely different environment and thus a completely different picture of the "telegraph war".

Although not a biography (I'm finding that quite a number of "famous" telegraphers have never been "biographed"), it does give insight into his life at this time.73, Chris Hausler

Hello Friends, April 23: Sunday propagation forecast (History?)

I noted this extract from the ARRL propagation broadcast of April 21:

Also, from today's page:

So, perhaps no surprise that today's (23 Apr) conditions are so awful.

M-flares, coronal holes and radio blackouts

This video, whose link I took from the CWops group, helps to explain why conditions today were so bad.

Talk of M-flares, Coronal Holes and Radio Blackouts over the coming week.

Published on Apr 20, 2017

The Sun shows its angry face again as two regions that sent us 7 big flares just two weeks ago rotate back into Earth view.

They have already fired off one near M-class flare and launched a non-Earth-directed solar storm.

Amateur radio operators should expect possible radio blackouts on the dayside of Earth this week.

Cootiebuilder&crystal radios

Dear Friends, slight off topic
...Paul ,ON4ADI besides building all sort of cooties on plexi , has another passion too:
MW DX-ing with (of course) home made crystal receivers (in French "postes a galènes") picture taken at on6wj's "foxhole" testing one "Cat's whisker" with large longwire antenna.

Just for info:
the game is open or Paul challenged me to break his record in spotting MW AM radiostations.
I have to hurry because nearly each day,somewhere there is final "closing down" of some AM Broadcast transmitter sadly to say...the Internet takes it all over
Have a good start of the week

13-05-17 / COSMIC RAYS INTENSIFY: The solar cycle is plunging to its lowest level in years.

As sunspots vanish and the sun's magnetic field weakens, cosmic rays are penetrating the inner Solar System in greater numbers than usual.

High-altitude balloon flights over California have detected the change in the form of increased radiation levels in our planet's atmosphere.

Visit today's edition of

to see the latest data and to learn how intensifying cosmic rays can affect us on Earth.

Nice and useful stuff, everyone wants this anyway?
