A German railway cannon used during World War II. The Dora cannon had a bore of 800mm and fired high explosive shells that were disigned to penetrate several meters deep into any surface. This cannon was cabable of knocking out ammunition storage areas deep under ground. This cannon was so large that it had to run on two sets of tracks, and it could only be turned when there was a turn in the tracks (the gun did not have a turret or similar device). The Dora cannon no longer exists. When the Allies found it, it was in pieces.
The only good that came from Hitler's reich was a multitude of awesome weapons, one being the Dora cannon.

There are many different types of radio receiving circuits:
-Crystal (see above)
-Regenerative
-Tuned Radio Frequency (TRF)
-Superheterodyne
-Crystal (see above)
-Regenerative
-Tuned Radio Frequency (TRF)
-Superheterodyne
Modern radios are superheterodyne. The superheterodyne circuit replaced the TRF and regenerative circuits by the 1930's, and crystal sets were nearly dead until solid state radio emerged.

An abbreviation for "Rate of Fire." This is used only over the internet when weaponry is the topic. Elsewhere, one would say "Rate of Fire"

The SI system makes more sense than the English system. It should be officially adopted by the US, but we Americans are too lazy for change.

see radio
A type of radio circuit that amplifies by feeding the output signal back into the input (regenerating) in such a manner that the signal is strenghtened.

If you improperly adjust the feedback on a regenerative receiver, it becomes a transmitter and will mess up the neighbors' radios!
