Yorkshire, 1943. Lily Baines, a bright young debutante increasingly ground down by an endless war, has traded in her white gloves for a set of headphones. It’s her job to intercept enemy naval communications and send them to Bletchley Park for decryption. The team, some of whom were licensed radio amateurs, consisted of Jan van Muijlwijk (CAMRAS); Tammo Jan Dijkema (CAMRAS); Thomas Telkamp (Lacuna Space), and Frank Zeppenfeldt (ESA). To achieve the transmission, the team used the Dwingeloo radio telescope, operated by the CAMRAS foundation in the Netherlands. The radio telescope has a history of being used in amateur radio experiments and is now often used for Moon bounces. In addition to the LoRa chips, the team used an SDR (software-defined radio) to capture both the transmitted and received signal for further analysis. These measurements together with analysis notebooks will be published as open data. An in-depth overview of the entire experiment and results will be presented at The Things Conference in January 2022. During any one lunar month (approximately 28 days) any two places on the globe will have mutual visibility of the moon, permitting communications by EME, to take place. At the extremes this may only be for a few minutes, but at shorter separations, such as with Europe or between Europe and North America, the moon may be mutually visible for many hours at a time.

Pistols for propulsion? It would bump you 10 inches… and the CO2 tank would get one of the crew a few hundred yards away. Fun, but futile. It's certainly a shot in the dark and thus begins a short friendship among two young people, living eighty years apart. Lily's always tried to lighten the mood with jokes, although this is no joking matter, war is no joking matter. Matt is from Texas and you can tell he is even though he's never roped a cow and never wants to do so. These two are funny but also desperate to stave off the destruction that is coming in the future, if only it's possible. Signal Moon by Kate Quinn was a brilliant piece of WWII fiction with a dash of speculative fiction thrown into the mix that I would highly recommend to everyone. Seriously, go read it now!EME regularly takes place on all amateur bands from 50MHz up to 47GHz, with 144MHz and 1296MHz by far the most popular bands for activity. Some EME activity has even taken place on the 21 and 28MHz amateur bands. This cookie, set by YouTube, registers a unique ID to store data on what videos from YouTube the user has seen.

Although most modes have been used with EME, until recently CW dominated. However the advent of weak-signal digital modes, such as JT65 and QRA64, has led to a significant rise in their popularity. Because of the higher sensitivity advantage of digital modes, it is possible to use smaller antennas and lower transmit power and this has permitted many more radio amateurs to become involved in EME.

The emotional-fool side of me feels let down by the bittersweet feelings it generated. ‘Ye Dil Maange More’, what to do! What they get is more than either of them ever bargained for. It’s enough – and it’s not nearly enough at all. The others laughed, a welcome sound of cheer in the chilly parlor. The little seaside hotel, in which Lily and her fellow Wrens had spent nearly every day of the last year, had been made over into a listening station at the start of the war. The space was crammed with desks, naval message pads, and National HRO receivers with their cranky dials and chunky headphones. The only part of the room that still looked like a parlor was the wallpaper, pink blotches that might have been cabbage roses or maybe diseased kidneys, writhing across the walls and down the corridor outside, and in all the rooms upstairs where Lily and her fellow Wrens billeted in a welter of hideous china and starched doilies. “This whole place is a mid-Victorian howler,” Lily had decreed their first day, already slotted into her place as court jester, the one who kept everyone laughing. This is a fun story that grabbed me from the start. I did the eBook/audio option so I could read and listen to the audio at the same time. The audio added a lot to the story. The audio was narrated by Saskia Maarleveld and Andrew Gibson. The sound affects made the story wonderful.
