From Wikipedia: "A tin can telephone is a type of acoustic (non-electrical) speech-transmitting device made up of two tin cans, paper cups or similarly shaped items attached to either end of a taut string or wire.
"It is a particular case of mechanical telephony, where sound (i.e., vibrations in the air) is converted into vibrations along liquid or solid medium. These vibrations are transmitted along the medium and then reconverted back to sound. In the case of tin can telephones the medium is a string."
I remember making and having fun with these with my buddies when I was a kid. I wonder if kids do that now. Probably not...

Former radio station Radio Kootwijk is a monumental building with a special history, in which connection is central. The building is architecturally unique, in its special Art Deco style.
Architect Julius Luthmann was commissioned in 1920 to build a hall for the large dynamo of long-wave radio transmission equipment. The desolate sand drift near Apeldoorn lent itself well to an interference-free transmitter. Luthmann was not allowed to use wood and iron, so it was made entirely of concrete. In the rich Netherlands of those days, no more or less was looked at. The design has been worked out to perfection and finished in Art Deco down to the last detail.
History:
At the start of the twentieth century, the Netherlands was a trading nation with extensive overseas territories. Its interests were served by a quick connection to the colonies, especially the Dutch East Indies. Direct communication took place by way of electric telegrams, which required cable connections. Prior to this, the Netherlands was dependent on England and Germany. When the First World War broke out the disadvantages of this dependence increased. In 1918, the government decided to realise their own international communication network, independent of the neighbouring countries. After much political debate it was decided to build a long wave transmission station enabling permanent contact with the Dutch East Indies using radio telegraphs.
To establish the radio transmitting station they looked for an uninhabited, remote terrain so there would be minimum interference to the transmission traffic from the environment. The 450 hectare terrain was bought by the Dutch Ministry of Transport, Public Works and Water Management from the Dutch National Forestry Commission.
About 150 labourers from Amsterdam levelled the terrain. The antenna terrain was constructed as a circular plain with a diameter of approximately 1200 metres, a ring of five 212 metre high masts around a central mast at the foot of the transmitter building. The radio transmission centre was officially put into operation in May 1923, initially for Morse telegraph traffic. The developments in radio technology advanced rapidly. After a few years it became apparent that the long wave connections were outdated and too expensive. They switched to a short wave frequency for a higher signalling rate, better connections, lower energy consumption and smaller equipment.
The station initially operated under the name Radio Assel, but also became known under the name Radio Hoog Buurlo. 'Kootwijk Radio' was the international call sign for radio traffic. Queen Emma brought about the first telephone connection in 1929 with the Dutch East Indies with the legendary words: “Hello Bandoeng Hello Bandoeng! Can you hear me?". The first conversations, which invariably concluded with the Dutch national anthem Wilhelmus, were free as it was still in an experimental phase. Subsequently, people had to pay considerable amounts for a phone call to family members overseas. The PTT (state enterprise for Post, Telegraphs and Telephony of the Netherlands) tried to interest the public in overseas phone calls through advertising. Cheap family phone calls, only on Saturdays with 30% discount off the normal rates cost f 21 in those days for a three minute call to Java, for example. In those days the average weekly salary was f 25.
This opportunity had me thinking of todays title because there is so very much at the top, and so little at the bottom. This theory purports that " tax breaks and benefits for corporations and the wealthy will trickle down to everyone else". This economic notion persists, although we are overwhelmingly witness to various corporations taking larger gross profit margins, while starving off and slowing down, exhausting payouts.
Take for example the world of telephony in our Country. Amalgamating companies should lead to fewer redundancies, thus decreasing corporate costs. Increased profits could then trickle down to customers and lower their bills. Instead, our waterfalls better illustrates any words I could harvest to explain what actually happens..
“When wireless is perfectly applied the whole earth will be converted into a huge brain, which in fact it is, all things being particles of a real and rhythmic whole. We shall be able to communicate with one another instantly, irrespective of distance. Not only this, but through television and telephony we shall see and hear one another as perfectly as though we were face to face, despite intervening distances of thousands of miles; and the instruments through which we shall be able to do this will be amazingly simple compared with our present telephone. A man will be able to carry one in his vest pocket.”

L'humour en photo de rue fait partie des gammes ordinaires du fêlé des rues...
Mais ici, si l'humour est esquissé, il m'apparaît cependant impératif de rappeler deux trois choses :
Primo : toutes les personnes en fauteuil n'en ont pas besoin H24. Certaines en ont besoin assez souvent pour sortir avec, mais se permettent de temps à autres une marche sur leurs deux jambes pour des trajets simples.
Secundo : toutes les personnes à mobilité réduite ne sont pas âgées ou "visiblement handicapées".
Tertio : ...Soyons sérieux : ce fauteuil est trop petit pour être le sien !
D'où ce titre : il n'y a point de miracle ici !
...Juste le quotidien des rues d'Alençon.
Radio Kootwijk is een voormalig zenderpark op de Veluwe, ten westen van de plaats Apeldoorn, dat in de eerste helft van de 20ste eeuw een belangrijke communicatieverbinding vormde tussen Nederland en zijn toenmalige koloniën, met name Nederlands-Indië || The housing accommodations of Radio Kootwijk arose as a result of the building of a shortwave radio transmitter with the same name, starting in 1918. The transmitter played an important role in the 20th century as a communication facility between the Netherlands and its then colony of Dutch East Indies. In 1923 Dutch PTT started trans-oceanic telegraphy using a longwave transmitter (a 400 kW high frequency alternator) from the German Telefunken company under the callsign PCG, on 24 kHz and 48 kHz. By 1925 the longwave transmitter was changed by a shortwave tube based, electronic transmitter which had a much better performance due to the better propagation of short waves. With this new technology, in 1928 a radio-telephonic connection was established. At the end of World War II, the German occupying forces blew up the transmitter. Afterward some of the radio towers were rebuilt. (Wikipedia)
My little garden friend was pecking the last of its coconut treat.
He or she was looking straight into my eyes, tying telephony, and it certainly worked.
Oh, yes, I got the message, alright 👍 up to my shed for a new coconut replacement.
I promised myself to mind my beautiful little feathery friends better than I had before, and I do try and accomplish this.
Fat balls 😋 dried worms and of course coconut half's filled with suet.
I also have bird baths for their other needs!!! 🐦
Love & Peace. Everyone ❤️

Hi robin, pray tell what do you see ?
An ape like person, maybe someone like me?
I think you're the sweetest bird ....
singing songs that I've never heard ....
You sing your songs 🎵 so happily gay ....
I love you robin you've made my day.

Radio Kootwijk is a small town in the Dutch municipality of Apeldoorn, with approximately 120 inhabitants (in 2006). It is situated in a heather- and forest-rich territory in the Veluwe region, east of the sandhills of the Kootwijkerzand and the town of Kootwijk.
The housing accommodations of Radio Kootwijk arose as a result of the building of a shortwave transmitter site with the same name, starting in 1918. The transmitters played an important role in the 20th century as a communication facility between the Netherlands and its then colony of Dutch East Indies. In 1923 Dutch PTT started trans-oceanic telegraphy using a longwave transmitter (a 400KW high frequency alternator) from the German Telefunken company under the callsign PCG, in the 24 kHz and 48 kHz. By 1925 the longwave transmitter was changed by a shortwave tube based, electronic transmitter which had a much better performance due to the better propagation of shortwaves. With this new technology, in 1928 a radio-telephonic connection was established. At the end of World War II, the German occupying forces blew up the transmitter. Afterward some of the radio towers were rebuilt.
Due to the development of new technologies like satellite communication and the internet, Radio Kootwijk lost its position as main overseas wireless connection point of the Netherlands. In 1980, the last transmission mast was blown up. In 2004 the park lost its last transmitter functions, and was transferred from the KPN company (successor to PTT) to the State Forestry Commission, which started attracting new buyers. The main building of the former transmitter park, designed by Dutch architect Julius Maria Luthmann and named 'Building A', 'The Cathedral' or sometimes 'The Sphynx', was officially appointed as a monument. It is used as venue and scenery for several cultural events and productions, including the American film Mindhunters in 2004.

It's retro, man! Way-back-when, telephones actually used to be plugged into the wall and the handset was attached to the base. The cable used to look just like this ;-)
An interesting bit of history here captured by the lens of the late great western rail photographer, Steve Schmollinger.
Maybe an SP expert can chime in on this, but some of you out there probably had SPRINT cellular service at one time. It was once the fourth largest cell service company with over 50 million customers.
Here's the interesting part: Few know that SPRINT actually had railroad origins:
Southern
Pacific
Railroad
Internal
Networking
Telephony
SPRINT came about in the early 70s - right around the time of this photo according to Steve's caption. It seems that it was a venture to offer long distance to customers as opposed to strictly internal railroad communication.
I'm not sure if we are looking at an example of SPRINT here, or if this is just a land-line used by rail employees. I suspect the later, but it reminded me of the interesting history of the SPRINT cell carrier.
Steve's caption reads:
"SP SD7 No. 2704 waits for a signal from the Valley-Mountain dispatcher in Bakersfield to proceed back down the mountain. Tehachapi, CA, 6/23/73."
A BRIEF HISTORY OF VOLK’S ELECTRIC RAILWAY
The son of a German clockmaker Magnus Volk was born at 35 (now 40) Western Road, Brighton on 19th October 1851. Educated in the town he was eventually apprenticed to a scientific instrument maker but on the death of his father in 1869 he returned home to assist his mother run the family business.
Scientific and engineering events in the wider world were of great interest to Magnus and he was forever experimenting with electricity, telegraphy and telephony. His growing prowess as an inventor and engineer and the fact that he was the first person in Brighton to equip his house with electric light, led to him being awarded the contract for providing the famous Royal Pavilion with electric incandescent lighting. Contacts made during this period were to prove very important with Magnus’s next and most long-lasting project.
1883 – 1900
The first railway, regauging and the extension to Paston Place
At noon on August 4th, 1883 Magnus presented the people of Brighton with his latest creation – an electric railway operating over a quarter of a mile of 2ft gauge line extending from a site on the seashore opposite the Aquarium to the Chain Pier. Power was provided by a 2hp Otto gas engine driving a Siemans D5 50 volt DC generator. The small electric car was fitted with a 1½hp motor giving a top speed of about 6mph.
The tinting of the original black and white photograph is our interpretation of the contemporary press description of the car. Magnus is standing on the left hand platform with the Mayor on the right.
A NEW DIRECTION
No sooner was the railway open than Magnus sought powers to extend it westwards along the beach to the town boundary. To his dismay the Council turned this proposition down so he reversed direction and succeeded in getting permission to extend eastwards from the Aquarium to the Banjo Groyne. He also secured the rental of the ‘Arch’ at Paston Place to provide workshop and power facilities. Following experience gained from the first line he also decided to widen the track gauge to 2’8½”, and he designed two more powerful and larger passenger cars.
Although the line would run along the seashore it still required a lot of timber trestles to bridge gaps in the shingle, and severe gradients down and up to allow the cars to pass under the Chain Pier. The picture to the left is from the cover of a book produced by Volk promoting his new railway. In the background can be seen the Chain Pier.
The new line opened on April 4th 1884 using one car. The uprated power plant in the ‘Arch’ consisted of an Otto 12 hp gas engine powering a Siemens D2 dynamo at 160 rpm. This gave an output of 160 volts at 40 amps – more than sufficient to propel the two new cars along the 1,400 yard long line. A station was provided adjacent to the Banjo Groyne, and a loop complete with halt was provided halfway along the track for cars to pass. With the arrival of the second car a 5 or 6 minute service was provided daily summer and winter (excepting Sundays until 1903) – weather and storm damage permitting. It says a lot for Magnus’s fortitude and engineering that this service operated right up until 1940 when the threat of invasion closed the railway for the duration.

This is one of Brighton’s landmark. It is still up and running. I have volunteered there through work supporting my students. The people at Volks are friendly, supportive and helpful.
Thank you for viewing. If you like please fav and leave a nice comment. Hope to see you here again. Have a wonderful day 😊

There are lots of photographers in the world, and some of them are artists. There are you and I, who in the presumption of the moment switch our cellphone from ear to eye to defy the ephemerality of telephony and freeze what is right in front of us; there are you and I who go a step further and sit dreaming with our Leica, dreaming of being a photographer like the photographers... whatever in the world that is. And then there are the photographers --- some of whom are artists.

There are still many little communities here which get all their telephony from these overhead cables.
Maybe not electric, but telephonic...

Please forgive the rotten scan, it's an old shot and I didn't have any other options at the time. Oh, to be able to go back and re-shoot...
As we were walking along the street, it stroke me as a sort of Tim Burton's Christmas Night scene.
Designed by Sir Giles Gilbert Scott, as a result of a competition by the Royal Fine Art Commission in 1924, and despite the initial opposition to their red color, these Kiosks are still a familiar sight on the streets of the United Kingdom, Malta, Bermuda and Gibraltar
In 1935 the K6 (kiosk number six) was designed to commemorate the silver jubilee of King George V. K6 was the first red telephone kiosk to be extensively used outside London, and many thousands were deployed in virtually every town and city, replacing most of the existing kiosks and establishing thousands of new sites. It has become a British icon, although it was not universally loved at the start.
The red color caused particular local difficulties and there were many requests for less visible colors. The red that is now much loved was then anything but, and the Post Office was forced into allowing a less strident grey with red glazing bars scheme for areas of natural and architectural beauty. Ironically, some of these areas that have preserved their telephone boxes have now painted them red.

Two men look at mobile phones atop a house in Uganda. Very soon the newly constructed house on which they are standing will be painted yellow. The other one is red. Most adjacent houses along the highways of Uganda are red and yellow - showing allegiance to either Celtel or MTN, the two main mobile telephony service providers in the country. While basic amenities such as potable water and hygiene have taken a backseat, the economic policies have created a greater rift between the rich and the poor and the country is run by corporate houses dealing in everything from oil to mobile services. One has to buy everything branded. Wonder if the roast cassava and skewers of roast beef are also going to be branded.

IRIDIUM83
Уже не мало было упоминаний здесь о спутниках "Иридиум". Но давайте теперь разберемся, что это за фрукт такой и с чем его едят, и почему его любят астрофотографы. "Иридиум" - это всемирный оператор спутниковой телефонной связи. На данный момент покрытие составляет 100% поверхности земли на НОО. После начала работы спутников была создана компания iridium inc. Данная компания держалась не долго позже заявил о банкротстве. Разрабатывался план свода спутников с орбиты. Но созданная компания iridium satellite llc выкупила все активы после чего продолжила работу. Позже контроль переходит к новой компании iridium communications inc.
За что их любят?
На фото можно заметить белую полоску на небе, нет, это не повреждённый объектив, именно это и есть вспышка "Иридиума" - это явление , вызываемое отражением солнечного света гладкими поверхностями антенн спутников. Некоторые вспышки могут быть очень яркими и достигать -9,5 звёздной величины, что производит большое впечатление ночью. На данный момент эти спутники в момент отражения солнечного света на Землю считаются самыми яркими объектами на небе.
Но почему приходит конец данным вспышкам?
Дело в том, что эти спутники устарели и им приходит замена на новое поколение спутников iridium NEXT, которые не будут отражать солнечный свет. Спутников было выведено 66 штук, осталось из них на данный момент 9. Спутников нового поколения будет выведено на НОО 75 штук.
There were already a few references to the satellites "Iridium". But now let's see what kind of fruit is this and what it is eaten with, and why astrophotographers love it. "Iridium" is the world operator of satellite telephony. At present, the coverage is 100% of the earth's surface at the DOE. After the commencement of the work of the satellites, the company iridium inc was established. This company was not long afterwards declared bankruptcy. A plan was developed for compiling satellites from orbit. But the established company iridium satellite llc bought all the assets and then continued to work. Later, control passes to the new company iridium communications inc.
For that they are loved?
In the photo you can see a white strip in the sky, no, it's not a damaged lens, this is exactly the flash of "Iridium" - this phenomenon caused by the reflection of sunlight by the smooth surfaces of satellite antennas. Some flashes can be very bright and reach -9.5 magnitude, which makes a great impression at night. At the moment, these satellites at the time of reflection of sunlight on Earth are considered the brightest objects in the sky.
But why does this flash happen?
The matter is that these satellites are outdated and they are replaced by a new generation of iridium NEXT satellites that will not reflect sunlight. The satellites were withdrawn 66 pieces, left of them at the moment 9. The new generation satellites will be displayed on the DOE 75 pieces.

This trio of classic red British telephone boxes are a very popular subject for both local and visiting photographers. This is them just after sunset - this was back in October, the tatty marks you can see on them are ripped remains of Fringe flyers and posters from the festival back in August. There are special spots for posting those and performers aren't supposed to put them on the historic phone boxes, but they do anyway. Looks fine to them during the fest, lots of colourful poster, but after they've gone we're left with this mess degrading the look of the phone boxes
