A 1944 educational poster titled the “Chart of Electromagnetic Radiations” was created by the W. M. Welch Scientific Co. It was absolutely crammed with diagrams describing the electromagnetic spectrum as a whole, together with tons of related scientific concepts that included some allocations of ...
In the following sections we will chart one possible course into the future where radio sensing capabilities on the Moon are scaled up from nothing as it is now, to single antennas, and then to bigger and bigger arrays of antenna forming more powerful radio interferometers. In the next year ...

According to Isle of Mann International Broadcasting (IOMIB) around 75% of radios have the long wave band on them. But when was the last time you tuned into long wave? For the cricket coverage on BBC Radio 4? Or when Atlantic 252 was pumping out its 'You're never more than a minute...
