    Question NDB Signal Range question

    AFCAD (and I assume ADE) allows the editor to place "NDB" beacons. The NDB having the greatest range (when such is assigned by the program) is the "HH" beacon, with a range of 112 nm. However, the help file indicates that the editor might manually alter that number. Does anyone know what the maximum range of a manually set HH NDB beacon might be? Or put another way, by adjusting the range manually, how far might the NDB be able to transmit?

    Thanks.

    I do believe the limit is 100NM using ADEX for FSX.

    If you try to set it above that the range will default back to 100NM.

    As Afcad uses it's own compiler it may allow a greater range, simply enough to find out. Try it.

    Thanks, Bean...

    That's what I intend to do. I was just hoping that someone might have some experience with it to make my "trial & error" process less tedious. Charles Wood, in his Earhart adventure, placed an NDB on the USCG Cutter Itasca off Howland and assigned a range of 222 nm to it. I know that FS9 will not permit that, so the only way he could have accomplished the range extension was with AFCAD or by building the *.bgl from scratch (I suppose that can be done somehow).

    Anyway, LF radio in that period had an average range of between 3-- and 6 or 600 nm, depending on atmospheric conditions, antenna height and transmitter power. If a realistic adventure is to be created using period electronics, range capability of the LF available to FS9 must be extended. That's all I'm trying to do.

    I have had some success by stringing overlapping NDBs together on a plot line and having them all transmit on the same frequency with the same code identifier, but that creates an extended oval signal, not the omni directional signal that would have been in use. Also, there are some minor problems that I hope further experimentation will solve.
