I'm a newbie trying to figure out some terms; can someone post what "dead key" and "swing wattage" means?
Thanks-

Darkhorse,
Dead Key = The power your radio puts out when you key the Mic and say Nothing.
Swing Wattage = The amount of Power your radio puts out when you key the Mic and say: AUDIOOOOOOOOOOOOOOOOOOOO.
Example say your Radio Dead Keys 4 Watts with no Voice. This is called DEAD KEY WATTAGE.
Then when you say AUDIOOOOOOOOO it will Swing to 8 Watts or more. This is SWING WATTAGE.
Hope this helps.

The TOP GUN Modulator Circuit, is a MAGNUM radio exclusive. Activating the modulator allows the radio operator to set the AM Power output level to as little as 1 watt carrier and still modulate (Swing)to 50 watts - without adding distoration.
Note! (This is on the MAGNUM S-3 Model)
The Power varies with the different MAGNUM Radios.
Hope this helps.

Thanks tech808, I need to learn more about all this; do you (or anyone) have any web addresses for sites that a newbie radio guy can go to learn some of this stuff?
Ok, next questions: whats it mean when someone says they talked such and such range barefoot? What is "skipping"? |

SKIP is NOT the same as DUCTING.
Ducting is a tempture inversion which BENDS radio signals back down. DUCTING gets BETTER with frequency.
SKIP is "E" OR "F" layer clouds and becomes LESS with frequency.
Geekster is right a silent key is a decesed HAM. |
