Hei,
I received the SWRadiogram show for this week and wanted to share my reception because it was surprisingly excellent for a broadcast coming from Florida all the way to the UK!
I decoded these broadcasts using my Xiaomi Mi A1 mobile running the Tivar app with the phone’s microphone next to the speaker of my Etón G3 connected to my 18m long copper wire.
I really enjoyed the number of pictures and also having music alongside the Olivia 64-2000. The music made all the difference for someone who has to listen to the digital sounds as they can be fatiguing!
I will now attempt to post the images and text from the Radiogram; wish me luck!

The event is open to all radio amateurs. Armed Forces Day is May 18, but the AFD Crossband Military-Amateur Radio event traditionally takes place 1 week earlier in order to avoid conflicting with Hamvention®. Complete information, including military stations, modes, and frequencies, is available on the US Army MARS website (1). "For more than 50 years, military and amateur stations have taken part in this event, which is only an exercise scenario, designed to include hobbyist and government radio operators alike," the event announcement said. "The AFD Crossband Test is a unique opportunity to test two-way communications between military communicators and radio stations in the Amateur Radio Service, as authorized in 47 CFR 97.111. These tests provide opportunities and challenges for radio operators to demonstrate individual technical skills in a tightly-controlled exercise scenario that does not impact any public or private communications." During the event, military stations in various locations will transmit on selected military frequencies and announce the specific ham frequencies they are monitoring. Military stations expected to be on the air for the event include those in Arizona, Japan, Hawaii, Okinawa, Washington, DC (and elsewhere in the contiguous states), the USS Midway, the USS Yorktown, the USS Iowa, LST-325, the US Naval Academy in Annapolis, and the Newport Naval Radio Station Museum in Rhode Island. The MARSCOMM and MARSRADIO nationwide networks will have multiple stations on the air across the continental US. An AFD message will be transmitted utilizing the Military Standard (MIL-STD) serial PSK waveform (M110) followed by MIL-STD Wide Shift FSK (850 Hz RTTY), as described in MIL-STD 188-110A/B. Technical information is available (2). The AFD message will also be sent in CW and RTTY, as indicated on the full schedule (1). http://www.arrl.org/news/annual-armed-forces-day-crossband-test-set-for-may-11 Notes: (1)http://www.usarmymars.org/events/armed-forces-day (2)http://www.n2ckh.com/MARS_ALE_FORUM/MSDMT.html Shortwave Radiogram now changes to MFSK64 ...

Please send your reception report to [email protected] From New Atlas: World's first laser radio transmitter/receiver paves way for ultra-high-speed Wi-Fi David Szondy 29 April 2019 Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have, for the first time, used a semiconductor laser to send and receive radio signals. The hybrid electronic-photonic device uses a laser to extract and transmit microwave signals, providing a data rate that may one day lead to ultra-high-speed Wi-Fi. Hearing Dean Martin singing "Volare" on the radio may not seem that earthshaking, but when it's the first radio transmission and reception using lasers, it's something a little special. According to the team behind the new technology, the laser not only emitted microwaves wirelessly, but also modulated them and received outside radio signals. Working on previous research by the team in 2017 and 2018, the laser radio works by means of an infrared laser frequency comb. A garden variety laser generates light at a single frequency, much like a violin playing a precise note as opposed to a white noise generator spewing out the whole spectrum of sound. In a frequency comb, the laser produces multiple beams at multiple frequencies that are evenly spaced apart like the teeth of a comb, hence the term. In 2018, the SEAS team found that the light "teeth" of the laser comb could be made to resonate against one another, causing the electrons in the cavity of the laser to oscillate at microwave frequencies in the radio band of the spectrum. In the top electrode of the device, there's an etched slot that acts as a dipole antenna, like the rabbit ears on an old-fashioned analog television. By modulating the comb, the team was able to encode data on the microwave emission. This was then transmitted by the antenna to its reception point, where it was picked up by a horn antenna before being filtered and decoded by a computer. In addition, the laser technology could also receive radio signals, and the laser's behavior could be controlled remotely using microwaves from a second device. "This all-in-one, integrated device, holds great promise for wireless communication," says Marco Piccardo, a postdoctoral fellow at SEAS. "While the dream of terahertz wireless communication is still a ways away, this research provides a clear roadmap showing how to get there." The research was published in the Proceedings of the National Academy of Sciences.

Although it was scheduled to close in June of 2019, it has now been given a new lease of life with an upgrade to the transmission mast. It will now stay in service for a minimum of two more years. The Irish diaspora in Britain are some of the main users of the service and they had been lobbying for it to continue. www.southgatearc.org/news/2019/april/irish-long-wave-station-gets-two-year-extension.htm See also (with links): https://ei7gl.blogspot.com/2019/04/rte-radio-service-on-252-khz-to-be.html Returning to MFSk32 ... k{;B!ceN0Udf RSID: MFSK32 @ 1499.2 Hzhe3aKoeitn g?d sid8 k zt enliRar This is Shortwave Radiogram in MFSK32 ...

Thank you for reading this post and I hope you enjoyed seeing my reception of this station!
Wow!! That is a very elaborate broadcast. To get that in the UK has to take some serious equipment and experience!! Love It!!!!
wow wenderful !! when i can get likethis nice radiogramme !! please let me know how work this
You’ll need one of a few choices of setup to receive this one:
1. A radio tuned to SWRadiogram + an Android phone with the Tivar app installed and running.
2. A radio and Fldigi running on a PC with the PCs audio in connected to the radio or the microphone hearing the radio.
3. An SDR + Fldigi with the sound piped into Fldigi via an app like GRQX or SDR#.
I hope these suggestions helped and please feel free to ask more questions!
