made my 1st one @ 10, had a huge quad copper antenna outside inbetween 2 trees. Listened to the "Bob Lacy Show" all the TIME!!! (Bob was the 70's version of Art Bell type AM talk show)

Here is the actual one, twas ez, spring loaded clips w/ pics of the components

YUUUP Im ready-i dot know squat but i want to l earn. Maybe it would be nice to have a school here in that it would be a step by step learning curve. I guess what im getting at is what do the markings mean. Like an ohm sign and things like this.The only reason i ask of this is because it is on a radio speaker i have. Im clueless and that not my avatar name-hahahaha However if one must have a radio when u have to BO then one could make it out of a tree branch. Just an analogy here lol- but when u have nothing out ther you would want the basics. This is what im after and if this could ever come to pass ill be the 1st student to sighn up. Maybe a morse code class also. I have been thinking about this.If all else ever failed one would go back to basics again . So why not know what you here and keep it 2nd nature. Just a thot from an old guy. Thanks - guys- E

OHMS = RESISTANCE

MOST speakers for example normally have an 8 ohm "load", in other words its not a direct "short", there is some resistance in there so if you would put an ohm meter across the 2 spkr leads, it would not read 0.0 (Dead short) but more like 7.5 - 8.2 ohms which is the amount of resistance. You must have resistance in order for a circuit to function properly.

electronics can be boiled down to this equation

V or E = I x R

which means I=current(amps) times R="Resistance" equals I or E="Voltage"

can be equated as such as well -     where I is the product of dividing the Voltage over the Resistance

its called Ohm's law, named after Georg Ohm.
