In addition to operating on a single frequency, the antenna radiation
patterns are quite small...with the sensitivity switch in the Low position,
you pretty much have to fly right over the antenna to get the sound and
light. But that is what they are for, after all...indicators of exact
position.

Hey Bob,

Thanks for straightening me up! I would have never known.

I am just surprised that my marker beacon never went off when I practiced
landings in my VFR lessons over at JAN (Jackson MS).

Here I thought I was "programming" the marker beacon with a "NAV1
interface".

Guess I took a simple thing and made it complex....
