A special feature on the music Lillibullero, a 17th-century English political song. The song is used by the BBC World Service. The tune can still surprise even though its over 300 years old.

The lattice splitting pad may be used to combine two audio sources into a single audio output or to derive two separate outputs from a single audio source. A characteristic of the lattice pad that makes it very desirable for audio work is the port to port isolation. When used as a splitter, output port to output port isolation is theoretically infinite if the pad resistor values match the input port source impedance. In combiner applications, input port to input port isolation is also theoretically infinite if the pad resistor values match the output port load impedance.

First up: a fantastic, surreal story about one very cold night, more than 70 years ago, in northern Russia, that leads us to marveling at cosmology, dropping toy horses in test tubes of water, and talking about bacteria. And arguing, for a year. Walter Murch (aka, the Godfather of The Godfather), joined by a team of scientists, leads us on what felt like the magical mystery tour of super cool science.

 Then, in the early 80s, the height of the Cold War, when something strange began happening off the coast of Sweden. The navy reported a mysterious sound deep below the surface of the ocean. Again, and again, and again they would hear it near their secret military bases, in their harbors, and up and down the Swedish coastline. 

After thorough analysis the navy was certain. The sound was an invasion into their waters, an act of war, the opening salvos of a possible nuclear annihilation. 

Or was it? Annie McEwen pulls us down into a deep-sea mystery, one of international intrigue that asks you to consider the possibility that maybe, just maybe, your deepest beliefs could be as solid as...air.

Introducing the Galcom Streamer, a turnkey solution allowing broadcasters to stream online without any software setup or programming needed.

The Galcom Streamer is a simple solution to stream live radio over the internet. Using Raspberry Pi* technology and hosting the streams on Galcom’s server, missionaries can reach their audience through their smartphones, tablets, laptops, or computers through the internet.

Frank selected two Electro-Voice 635A omnidirectional mics. Imagine your reporter holding the top microphone within about 2 or 3 inches of their mouth, while the bottom microphone is pointing away from the mouth. Crowd noise is picked up equally by each 635A mic, thus the crowd noise is suppressed — virtually canceled!

You can experiment with pattern types; Frank finds that it works best with identical omnidirectionals, and the 635As are inexpensive, under $150 each.

The first photo shows the parts you’ll need to construct this project. Once you’ve gathered them, follow Frank’s step-by-step instructions.
