When was the 1st home voice radio and 1st 2 way transmitter, receiver and transceiver?

Old family information says my grandfathers older brother was a radio operator during WWI. What type transmitter was used in WWI? My guess is morse code? If there was a transmitter there had to be a receiver. When were voice transmitter and receivers also transceivers invented? All the old WWII movies show CW.

Online is not clear, they say something was transmitted but don't say, voice or CW code?

Explanation
  • In 1894, Marconi built a device that could ring a bell from 30 feet away.

  • In 1895, Marconi transmitted a Morse code message over a kilometer away.

  • In 1896, Marconi patented his wireless telegraphy system in England.

  • In 1901, Marconi transmitted the first signal across the Atlantic Ocean.

  • In 1906, Marconi and Ferdinand Braun won the Nobel Prize in Physics for their contributions to wireless telegraphy.

  • Marconi's work was based on the work of other scientists, including James Clerk Maxwell, Heinrich Hertz, and Oliver Lodge.
In February 1907 music was transmitted electronic telharmonium music from a laboratory.

July 1907 ship-to-shore transmission.

The Dutch company Nederlandsche Radio-Industrie and its owner-engineer, Hanso Idzerda, made its first regular entertainment radio broadcast over station PCGG from its workshop in The Hague on 6 November 1919. The company manufactured both transmitters and receivers.
 
December 23, 1900

The link will directly jump down to Fressenden in the Wikipedia article.

Invention of radio - Wikipedia

en.m.wikipedia.org

"In 1900, construction began on a large radio transmitting alternator. Fessenden, experimenting with a high-frequency spark transmitter, successfully transmitted speech on 23 December 1900, over a distance of about 1.6 kilometres (0.99 mi), the first audio radio transmission. Early in 1901 the Weather Bureau officially installed Fessenden at Wier's Point, Roanoke Island, North Carolina, and he made experimental transmissions across water to a station located about 5 miles (8.0 km) west of Cape Hatteras, the distance between the two stations being roughly 50 miles (80 km).[154] An alternator of 1 kW output at 10 kilohertz was built in 1902. The credit for the development of this machine is due to Charles Proteus Steinmetz, Caryl D. Haskins, Ernst Alexanderson, John T. H. Dempster, Henry Geisenhoner, Adam Stein, Jr., and F. P. Mansbendel.[31]"
 

Morse was used because it was so much more efficient, and much simpler and smaller - this continued in WWII as well, for the same reasons - although voice communications was used as well. My friends father (who died just the other year) was taught morse during his National Service, after WWII.

This claim has been deemed suspicious. The receiver only captured one "s" in Morse Code at about the time of the planned transmission. "S" is a dot-dot-dot which could be confused with static of a low quality receiver technology of the day. Marconi never published what the repeated message was supposed to say, but he only received an occasional dot-dot-dot. Since it was good enough for Marconi, it was good enough for the press, investors, and politicians.
 

I watch all the history I can find it is very interesting. During WWII England was smarter than USA the Americans were stupid in the begging and slow to get up to speed with England. British codebreakers at Bletchley park. Spies behind enemy lines memorized the 1 tube CW code circuit and how to build one behind enemy lines. England invented the magnetron, proximity fuse, high Hz radar, chaff, inflatable fake army tanks and inflatable fake airplanes, Raspberry, MI5, Operation Greenup, white mouse, limping lady and more. England was also breaking German and Japanese codes.

2 years ago I saw on TV England construction crew hit a German 500 lb. bomb and set it off killing 2 people. England sent Germany the Bill and expects them to pay $ for damage and killing 2 people.

I thought detonators were charged capacitor operator and battery operated? How is a charged capacitor and battery still good 80 years later? UXB videos were very educational also.

I wonder when the first, lathe, drill press and milling machine, was invented?

I visited Bletchley Park twice the other year, a VERY, VERY interesting place, well worth a visit (or two).

On the same site is a computer museum, where they have recreated a copy of the first ever computer that was used at Bletchley, and also Bombes (which were a machine that was part of the decoding process). We were talking to one of the guys who works there and he mentioned that a few weeks earlier an elderly couple were visiting, and they were demonstrating how the Bombe was actually used - and the old lady said "excuse me, you're doing that wrong" - so he asked how did she know, she replied that she worked at Bletchley in the war, and loading the Bombe was her job. Her husband then said "you worked here?, I worked here as well". They had been married since just after WWII and had never told each other that they worked at Bletchley during the war.

On a similar theme, a lady my wife knew called Josie Fisher (she was head mistress of a local Primary school) admitted a few years ago (when it was declassified) that she worked at Bletchley during the war, but refused to give any details. However, as she was a mathematician at Cambridge or Oxford University, it seems likely she was a code breaker under Alan Turin, as that's where they recruited the code breakers from.

Even now, after it's been declassified, employees who worked there are still keeping it fairly secret, obviously they took signing the official secrets act pretty seriously back then.

My French and Belgian acquaintances didn't seem to understand the effort, expense, and sacrifices made on their behalf either. Their history lessons pretty much summarized the hardship they endured at the hands of the Germans, the heros of the resistance efforts followed by a rapid page turn to: the allies came and the war ended.

I can understand that the occupation by the Germans was traumatic and my history classes covered very little of their experiences so it only makes sense that they don't cover much of the experiences of the British and American war efforts.
 
If the population of Europe is about 700M and only $140million worth of international tickets were sold for the movie (at about $10 each), let me know what fraction of Europeans have seen the movie? Something under 2% (since most of those non-US ticket sales were in the UK. So to answer your question, it's unlikely that they've seen the movie.

Data is easily available, such questions can be easily researched. That means, it's easier to answer your own question before asking such nonsense here.
