Beeping Thing

Allen,

I'm just now learning about all this IFR stuff so I could be wrong
here. I'm under the impression that the markers are on "fixed"
frequencies not associatied with the NAVs.

I will look into this more...

Yup, they are low powered (3W) with a directional output (up). You fly over
it, and the marker beacon receives it.

Alan, all marker beacons transmit on 75Mhz. No way you are going to turn one
off by changing ILS freq. I think the audio panel suggestions are closer to
the solution.

Hey Slick,

Person before you probably was doing an ILS approach into your airport and
had NAV1 set up for the ILS for runway 32. As you climbed out, you passed
over the marker beacons that are designed for ILS approaches for runway
32.

Just turn the NAV1 frequency to another frequency, and that would have
turned the marker beacon off.

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....

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.

O.K. so it sounds like I had the right idea about how to turn it off, I just
didn't go far enough with it. I was switching frequencies on the stack radio
NAV, but I didn't try to change the GPS NAV, I think I might have gotten rid
of it there. I couldn't find a mute button anywhere next to the lights.

The marker beacon is an independent radio reciever that is not connected
to the nav radio whatsoever. It may or may not be integrated with the
audio panel, but there usually is a mute or speaker switch associated
with it. Changing the nav radio should have no effect on the marker
beacon reciever, since the same marker beacon reciever frequency is used
across the entire country (and world, if I remember right)

It might be worth your time to go to:

www.garmin.com

www.bendixking.com

Check out their Audio Panels. Both sites have downloadable POH's for their
units that would help you know what's going on the next time you confront
the problem.

Maybe she wasn't scared by the beeps, but rather because she discovered
that you were flying in a plane you even didn't know the switches. A
very reasonable scare.

Any tips on how to turn it off?
