[ARC5] NDB useful range ?

[William Cromwell]

Hi Hue,

There are some interesting replies to this that include aircraft 
experience. Some of us hunt for and log NDB stations from our home or 
portable stations. I have logged some low power (~25 watts) NDBs in the 
favored direction of my antenna (northeast) out to 1500 miles and a very 
low powered 630 meter ham transmitter due south at 1200 miles. My 
antenna could be mounted on a large aircraft  and would look like a 
matchstick on a railroad boxcar! I probably have a much better ground 
connection:)

73,
