RCA Window from MI-7330
Four weeks ago, we announced a new contest to celebrate the SWLing Post‘s 10th Anniversary.
The prize is an amazing piece of broadcast history: a 75 year old round plate glass window that was fitted in the central main door of the RCA senders at the Woofferton, UK, transmitting site in 1943. This prize was generously donated by SWLing Post contributor and friend, Dave Porter (G4OYX).
Please read our original contest post (click here) which describes how you can enter to win.
The original post also contains the first of five contest questions which count as individual entries in the contest. The second question can be found here, the third question by clicking here and the fourth here.
Today, we present our final question…
Please note: This contest will close on Friday December 14 at 12:00 UTC–you have until then to submit answers to all five questions. The winner will be announced once we verify contact with them. If you have entered this contest, please check your email this weekend.
If you read the SWLing Post email digest, you will need to view our prize questions on the web to see the embedded form. If the form below does not display, click here to open it in a new window.

Have any Post readers heard this station? I would love to hear a recording or see this station on a spectrum display.
Many thanks to SWLing Post contributor, Ron Chester (W6AZ), who writes:
Have you seen this site from Duke University’s Center For Documentary Studies?
Shortwave is so cool that the digital nerds are now working on reproducing it on the Internet. It’s got a great interface, authentic sounding noise between stations, a train passing by on one station, some nice music, several interesting spoken pieces and at least two undocumented stations, one a numbers station, maybe both. It even has an audio to text display rolling across the bottom. If you haven’t already posted it on the SWLing Post, I think folks there would enjoy it a lot. I certainly did!
Thank you, Ron. I love the interface and think it’s fascinating that they chose the metaphor of shortwave radio as a means of interacting with these audio pieces.
Thank you for sharing!
