Using CS400i as Binaural Deriver

Dear Tour,

Here's a blast: "Daaaaiiisssy, Daaaaaiissy...."

Sorry about those from-hunger photos. I use this camera for taking pictures of construction defects in power plants and up on towers. Maybe I need a new one one of these days.

I'll try again. Here's a pic for "H-Bomb too" Every home needs one of these. I figure that when the bell rings I'll have about 3 milliseconds before the house vaporizes, which hardly gives the sound wave of the bell ringing to rattle my eardrums, but, a warning is a warning. The funny thing is that the unit is mounted on shock absorbers. Maybe it's meant for installation in a missle silo and not a private home. I'll have to write a letter to the manufacturer and inquire......

By the way, thanks for all your hospitality on the reflector here.

Hal

Dear Mr. Definitive,

Let's say you're listening to a radio program originating thousands of miles away on shortwave. The wave the station is transmitting, being on shortwave, is perhaps over 100 feet long.

This wave travels up to the ionosphere, bounces down, hits the earth, bounces up, and continues to do so with your receiver somewhere in the path.

Because the ionosphere is not a shining mirror held stationary up over the earth at 130 miles altitude, and because it resembles the surface of a pot of water boiling rapidly, various parts of the waves hitting it are reflected at slightly different times, and this results in atmospheric fading as a receive-type interference. Very annoying as the good parts you're listening to just fade away.

If you were to use two receivers, one with your antenna pointed North and South, and another receiver with the antenna pointed East and West, the part of the wave that was delayed by the ionosphere might be picked up by an antenna pointed in another direction but at a slightly different time.

Using a binaural speaker, the two radios can play at the same time and the sound emitted will seem to originate from the same place.

Tuning one of the radios slightly off frequency, like 10 hertz or so, will offset the Doppler shift effect and the binaural speaker will again blend the two audio signals into a cohesive image.

Fifteen years ago I participated in Earth-Moon-Earth radio paths bouncing 450 MHz signals from the moon and was simply astounded when hearing the first echoes from the moon because they "shook" a certain way, and thast was explained to me as being "libration," or the effect of the entire moon wobbling along in its orbit and the 23 centimeter wavelength radio signal was acting like a Doppler radar with the effect of libration heard in the audio signal.

As well, when participating with the Mars Observer satellite team in developing a method to quickly retrieve images from the satellite I used a bird some 58,000 miles in altitude to relay images and experienced the wobbling reflections as the satellite spun, wobbled and travelled in its orbit going closer to or further away from the planet.

The entire point of all this is pure science. It has no practical application. It's done just so I could experience its effects and report to you and others of its success or failure to resolve aural images better than a single receiver/antenna on the same channel.

Respectfully,

Hal
