Radio help

I need help in understanding something about radios or to gain insight I don't currently possess.

Bill Wall amassed a collection of radio inspired chess facts here:   http://billwall.phpwebhosting.com/articles/radio.htm

Note he mentions:
"In May 1927, a 12,000 mile wireless radio match was played between the London House of Commons and the Australian Parliamentarians in Canberra, Australia."

And a few lines later he states, "In 1945, the first International Radio Chess Match was held." 

Wouldn't the first international radio match have been in 1927  or was there some difference in radios between 1927 and 1945? 

Mr. Wall also uses these terms:

"wireless telegraphy chess match"
"wireless radio match"
"radio match"

I would think that all radio transmissions use radio waves and are by definition "wireless."  If that's the case, is the word wireless superfluous?

How is wireless telegraphy different from radio?

I'm afraid I can't help with the "radio" aspect of the question, but the distinction between the 1927 and 1945 matches may hinge more on a political definition. In 1927, Australia was a Dominion of the UK (semi-independent polities under the British Crown), so perhaps it wasn't considered "international" as both participant's had the same ruler.

boydcarts, thank you. I hadn't thought of that and it makes complete sense.

Anyone have any ideas about the radio terms?

Just a wild guess, batgirl, but I would think that wireless telegraphy means that dots and dashes (Morse code) signaled the moves, while plain old radio would mean that voice carried over the airwaves called the moves. 

Except in radio chess games the moves were transmitted was by code, not voice.

Yes that was what I meant to say, sorry to seem to be so confused here. I had not seen Jonthepawn's post earlier, sorry.

Batgirl,

I'm not an expert on the history of radio, but it is true that many individuals contributed to developing radio and the transmission of sound using electromagnetic waves.  Guglielmo Marconi invented the first apparatus for long distance radio communication essentially replacing wired telegraph 1830s and the transatlantic cable systems in use since 1860s. 

Terminology of the day was to call this the "wireless" telegraph or simply a wireless.  The Marconi company had stations used to broadcast from Europe to the Americas and ships at sea in the early 1900s.  Probably the most notable was the use of wireless (radio) telegraphic transmissions of the ice pack that were ignored, but could very well have avoided disaster for RMS Titanic in 1912.  Both wireless operators on board worked for the Marconi company and not White Star Line.

Telegraphy is long distance transmission using code (signals) and not sound like flags, smoke or light to exchange a message.  So these early electrical devices basically generated sparks which could be used to send a coded message between sender and receiver.  Wireless precedes radio as we know it today.  Radio telephony came into use in the 1920s and would displace telegraph systems.

Let me shed some light on the radio part.

A long time ago, the term "wireless" was the crazy hot buzzword.  So everybody wanted to just add it to everything.  E.g. "Dr MLK's inspirational wireless voice speech", "wireless sighting of the chessboard", "wireless Ethernet", etc.  Therefore, it shouldn't be a surprise to see "wireless radio".

As for the 1927 vs 1945 chess game, I think the reason 1927 wasn't termed International was because at that time every country was planning on conquering the world, so it wouldn't be too PC to ack the existence of others of equal status.

The Gringmuth Code, usually called the Udemann Code though the two were slightly different,  was used for transmission of chess moves via telegraph as early as 1866. This same code was used in the 1945 USA-USSR Radio Match, and I know for a fact, even in 1950.  So, it would seem to very little difference, practically speaking of course, in telegraph, wireless telegraph and radio - as far as chess matches go. 

Is there a difference between ship-to-shore radio, short wave radio, wireless radio... or are these term used to describe similar technology?

Interesting topic in itself.  I see you covered this before.  Thanks BG.

You can't do standard telegraphy without telegraph wires, consequently, wireless telegraphy isn't telegraphy at all, so it requires some other medium of transmission; radio, flashes of light, maybe even a guy doing semaphore, but he would be hard to make out from 12,000 miles away.   

Telegraphic chess, wireless telegraphic chess, radio chess, whether alike of different, all seem to use similar transmission techniques.   I'm really not concerned with telegraphs for what I'm working on - just wireless instruments and what makes each of them different, if in fact they are different.

You can read about the Udemann Code on the 1945 Radio Match website:  http://batgirl.x10host.com/index.html

Wireless telegraphy and radio are different as one uses codes (Morse) and the other sound for transmitting messages.   Shortwave is by definition limited to certain radio frequencies.

From what I've quickly seen on the 1945 radio match and you confirmed, the moves were made using the Uedemann (Gringmuth) code and likely done with radio telegraphy.

Video on this link appears to show a teletype machine for this.

In essence, wireless (radio) telegraphy as discussed earlier.
