My KR85 audio is strong but the needle wanders and will just not settle down.  Any suggestions on cause or reasonable repair facility?

The real reason to remove an ADF is that if you ever take a checkride with one installed, the examiner might make you try to navigate with it.

Still on the written for Private, Instrument and Commercial.

I was mainly joking. I did an NDB approach for my IFR check ride in 1995 and later flew a few NDB approaches, but GPS makes it so much easier. They still use ADFs frequently in other parts of the world. I mainly used mine to listen to a baseball game on a long flight.

Isn't an INOP label meant to prevent this from happening? ;)

I deep sixed mine after I read how to do an ADF approach.  I have no regrets.

Unless you fly in Alaska, why would you want to keep an ADF?
Is there even a remaining field in the Continental US only served by ADF approach - I doubt it, but interested to know.

There are a few in S Texas, and KMFE use to have an ILS that required ADF for the Outer Marker, would have to look and see

One of the approaches into Morristown, NJ still uses an ADF as part of the Missed approach...

So essentially, it is a waypoint in the GPS’ database...

+1 for inflight entertainment...

but, realistically a BT connection into the audio panel isn’t that hard to come by...

:)

For Steve’s wandering needle... start with cleaning connections, see what has come loose, or corroded....

PP thoughts only, not an instrument guru...

Best regards,

Robert,  Thanks:  Don, at Gulf Avionics, was very helpful.  He suggested a careful cleaning on antenna connector as a start.  Also, said that would look at unit and give me a repair quote.  They did have the harnesses on hand.

But unless any of those fields are ONLY served by an ADF approach then they have lost their utility IMO since there are better options. Like Anthony said, that "required" ADF for the middle marker identification is just a (FAF) Gps waypoint with any IFR GPS.

The irony of the lack of utility of ADF is that it's only "real" utility is that you need the ADF operational in the plane just to be "legal" to fly the ADF approach with an IFR GPS; since legally the raw ADF signal needs to be monitored while flying it with your GPS.

Just checked, VOR RWY 14 at KMFE requires ADF or DME, KHBV has an NDB RWY 13, there are a few more but I can barely spell ADF let alone shoot an approach with one

No problem, Don is the go to guy in this area to get the older boxes repaired

Its a wonder the FAA doesn’t still have range navigation on the written.

The USCG had a LORAN station down here until 2010ish, might have to fly around and see if the facility is still there

Sure there are uses of ADF in many places. But none of them are truly required anymore. Take your KHBV NDB approach example, yet we find there is a GPS LPV approach to the same runway. Why would anyone fly an NDB approach anymore when we have much better options?
I don’t even know of any instrument students that have even been trained in NDB approaches in last couple decades - not when a GNS430 is common on most trainers including C150s. But obviously there are still many Mooney’s without an IFR GPS and I’ve trained in many that way.

answered your own question.... and Mooney's aren't alone, but I did see a Cherokee 140 about 10yrs ago with dual 430's in it for sale, basically buying the panel and you got a tired 140 for free

I certainly have been known to go out in the middle of the night and put an INOP sticker on the ADF receiver before a student's checkride.

I am in the process of installing an adf in my M20D.  I don't like having to update the gps database every few months and I got the ADF for $100.  I can pick up KMOX in st louis anywhere east of the rockies at 10k ft.  I am sure there are lots of other am stations out there also that work.  Is it as good as a GPS?  No it is not.  It is a lot easier to use and cheaper to install and maintain though.

In the southeast US along the coast, there are many times per year when GPS isn't available, sometimes for days. Due to military operations around Savannah, or off the Space Coast of Florida, so you need VOR navigation, or the ADF. Not to mention solar flare activity that degrades it with no warning. I'm hanging onto some old school nav devices alongside my wiz-bang state of the art Garmin goodies because I've found I've needed it more than once a year.

Wouldn't VOR and DME be preferable to ADF?  I'm actually planning on removing an ADF to make room for an EDM...
