I'm changing "was the first to publicly demonstrate transmission of radio waves (March 1896)" to "was one the first to publicly demonstrate transmission of radio waves (March 1896)" and removing all mention of a patent application. Nicola Tesla demonstrated wireless broadcasting of messages while in St. Louis in 1893, and Marconi is credited with demonstrating radio in 1895. -- Ostermana 05:49, 12 December 2005 (UTC)
Whoa! In 1893 there were no printed documents that would confirm "public demonstration of radio waves" by Tesla. What about depiction of his transmitter and receiver "designed in 1893"? Maybe, one could find something in American museums? Same for "demonstrating radio signals by Marconi in 1895". No any written sources. Popov's experiments were very-well depicted in journals and newspapers printed in 1895. His system of wireles telegraphy was used in rescue operation while Marconi was trying to send a letter "S" over Atlantic. Sea diver ( talk) 13:12, 29 December 2007 (UTC) Sea diver
...can this article be a featured article?!?!?
The language is horrible. If I read this article aloud, it sounds... Russian! The word "a" should be used more often for example... —The preceding unsigned comment was added by 217.140.2.129 ( talk) 16:18, 7 May 2007 (UTC).
List his birthday as January 13/December 31 1905/6 doesn't make sense. It seems like you're saying January 13, 1905 OR December 3, 1906... Changed it for clarification. Jg325 16:39, 7 May 2007 (UTC)
Can somebody mention the trial with Marconi, which one has copied and claimed all inventions by Popov. I'm not expert enough to do that and my English is not the best. —Preceding unsigned comment added by 81.223.104.34 ( talk) 15:57, 7 November 2007 (UTC)
I think the text on the stamp deserves a translation. It says: "Inventor of radio A. S. Popov". And at the bottom: "Demonstration of the first radio receiver, 1895. Painting by N. A. Sysoyev."

Fountains of Bryn Mawr, I think the notable fact that Popov (along with Marconi) is popularly credited in numerous sources 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 with building the first radio receiver needs to be in the article. Glad you caught the Landell de Moura reference. BTW, if de Moura didn't use radio waves, there are claims in Radio, Wireless telegraphy, Invention of radio, List of scientific priority disputes, and 1900 in Brazil that need to be removed. -- Chetvorno TALK 19:56, 3 March 2014 (UTC)
Fountains of Bryn Mawr, I left that in because it is actually his first receiver, as shown in Huurdman, p.207. It is the only PD picture I could find. The photo of the receiver with the chart recorder which you left in was not actually his first receiver - the caption lies. I think if we can't find a better one the drawing needs to be in there. -- Chetvorno TALK 22:02, 3 March 2014 (UTC)
Fountains of Bryn Mawr, I think it is splitting hairs not to call this a "radio receiver" in the article. The introduction calls it that. It did, in fact, receive radio waves, producing an audible signal. Sources are unanimous that it was demonstrated receiving manmade radio signals on May 7, 1894; the only question is when it was used to receive communication, intelligent signals, Morse code. It obviously could have been used to receive Morse code at any time. Its construction as a permanent self-contained piece of equipment, its audio signalling ability, and its ability to produce a permanent record on a siphon recorder, set it apart from laboratory demonstrations of reception with galvanometers like Lodge's. It was almost identical to Marconi's receiver, which no one argues was not a redio receiver. Popov's statement in his paper, quoted in the article:
I can express my hope that my apparatus will be applied for signaling at great distances by electric vibrations of high frequency, as soon as there will be invented a more powerful generator of such vibrations.
shows that he was aware of its communications ability; the reason he developed it as a lightning detector is that he didn't believe spark-gap transmitters were capable of long distance communication. After Marconi demonstrated long distance communication in 1896 he developed it as a Morse code receiver and by March 1897 was communicating with ships at sea 1, 2. WP:RELIABLE SOURCES are divided on what they call it, but there are plenty 3, 4, 5, 5, 6, 7 that describe it as a radio receiver. Calling it a "lightning detector" is liable to confuse casual readers, implying that lighning noise was all it could receive.
Besides, modern lightning detector circuits 8, 9, are described as radio receivers. -- Chetvorno TALK 23:28, 16 July 2014 (UTC)
