ADF
Automatic Direction Finder or Automatic Direction Finding System a navagation system used by aircraft and sea-going ships. It consists of one or more ground stations that transmit a signal in the 225 to 500 kHz (.225 to .500 MHz) range. Because of the low-frequnecy of these signals, their range is very good and not limited by the line-of-sight range of the VOR system. The recevier in the airplane/boat uses a loop antenna to "home-in" on the station. There is also a long-wire receiving antenna installed on many aircraft. Most ADF receivers can also recieve the AM broadcast band (530 to 1710 kHz) so pilots can also home in on powerful broadcast stations. ADF signals should not be used in thunderstorms because the high amount of electro-magnetic interferance that lightening causes. Many pilots can't even use the ADF system, which is a shame, becuase of better systems such as VOR and the GPS systems.

This mug makes me happy :) reminds me of so many funny high school memories!
The mug came quickly and we love it!
These mugs are always good. I usually choose the neon green!
The mug is pretty and the writing on it is clear. It is of good quality and it makes me smile.
Well madder nice print. 8 0z cup. I'd prefer a mug but will be ordering 3 more. Just my cuppa tea (or coffee). Americans always make fun of some of the things I say. Recently my brother and I were talking about the Trawna Maple Leafs. I decided to look it up and sure enough there is was Trawna the city I grew up in. Now who has the last laugh.
I ordered pink but got purple, and the text wasn't very clean, but overall, it is a mug.
It was a gift for my sister, who wrote it. She loved it and so did I!
