Donation to Jews for Jesus        03/31/16

I am author Frederick Hoehn.  I have ebooks available at Barnesandnoble.com   I also have a technical background.  

This is a DONATION to Jews for Jesus.  

What I am donating is an invention of mine to Jews for Jesus.  

I got the idea years ago, and thought that eventually I might market the product, an improved AM radio, but because of my age, it looks like I won't be getting to it.  

In various textbooks, there are schematic diagrams of superhetrodyne AM radio receivers.  

When you get down to the lowest Intermediate Frequency (IF), then what they do is to use a diode rectifier to extract the audio frequencies.

The AF is then filtered with a capacitor, and amplified.

But using a single diode rectifier throws away half the power because it provides only half-wave rectification.  

So instead, use four solid state rectifiers as a bridge rectifier, and get full wave rectification.  This will double the power.  

But also, don't use silicon diodes because there is a 0.7 volt drop across a forward biased silicon diode.

Instead, use germanium diodes, which have only a 0.2 volt drop across a forward biased germanium diode.  

This doubles the output power and makes the radio more sensitive.  This is particularly important for small, neck worn, battery-operated AM radios.

This invention is my DONATION to Jews for Jesus.  You can do with it as you please.  I believe it's worth money that can be used to win Jews for Jesus.  

I believe I'm already on your mailing list, but please see new address below.
