Is it possible, and does anyone know how, to connected a western ADF to the Gyro compass in the Yak-52?

Better yet can a portable or panel mount GPS turn the needle in the HSI-gyro compass?

In most of the western world the instruments have electrical interfaces
that adhere to standards set forth by ARINC. Most older instruments that
have a 360 degree heading indication are driven by a five-wire AC
synchro resolver signal running at about 26VAC. (There is an ARINC
number but I forget what it is.) If the Russians adhered to that
standard then you should be able to drive the Russian indicator from a
good ADF with a synchro resolver output. The King KR-87 comes to mind here.
Most electromechanical HSI indicators use the aforementioned synchro
resolver signal to provide heading indication. A GPS will output digital
heading data either in the form of NMEA-0183 (marine standard) or
ARINC-429 (aviation standard), neither of which an older HSI
understands. If you have a newer electronic HSI it *may* understand
ARINC-429 heading data.
BTW, if you are doing a new panel it makes a lot of sense (and a lot
less wire and complexity to boot) to go with ARINC-429 wiring for
heading (and other) data but you can't use older instruments. OTOH,
instead of the HSI needing a minimum of about 15 wires to operate,
ARINC-429 can do it all with only two wires because all the signals;
i.e. CDI, VDI, to/from flag, GS flag, and heading; are multiplexed.

It is my understanding that most NDB's are no longer being monitored or maintained. (Other than those that serve as LOM).
My airline does not even train or allow us to shoot NDB approaches. If I had to do one..well...it would be ugly.
I agree that the GPS would be the cheaper and more accurate way to go. Only draw back, you cannot listen to Rush Limbaugh on a GPS!

True enough. They are going away. But until they do, you can still use them.

They turn out to be useful occasionally as I will indicate below.

Well, I may have posted this here but here goes again. Last year as I
was flying over water from the USVI to Florida my GPS just up and went
away. Nothing. Nada. Fortunately I was able to pick up the NDB at Great
Inagua, my fueling stop. No problem. Track the NDB inbound. (I was able
to pick it up 500nm away even in daylight!) Got fuel and then did
something I haven't done in many years, I tracked it outbound toward
Stella Maris and Nassau figuring I would pick up the VOR at Nassau and
would complete the trip using VOR navigation. The GPS came back around
Stella Maris (about 100nm later) and I was only about 5nm off course. I
can live with that at the end of tracking an NDB bearing outbound.
So, GPS *does* go away and NDB/ADF is still useful in many parts of the
world. I just put a KR-87 in the Aztruck and am happy I did. When all
else fails I can track that AM station broadcast Rush and then find a
place to land.

I can tell you with confidence that any FAA device that is published for use in aircraft navigation or approaches is required to be monitored and maintained, and they indeed are. That said, there is not much to them really. Just a big ole A.M. transmitter. The only thing that is watched is:
Power Output,
Percentage of Modulation
Assigned Frequency (has to be smack dead on)
Spurious Products
The final output tubes are usually changed on a preventative maint. schedule. 4-1000's anyone?

Tim,
Obviously you have the wrong GPS unit. You can too listen to Rush Limbaugh
on a GPS! Can you guess which one?
Hint: it is made by Garmin, it is portable (hand held), and also gives you
weather...if you subscribe that is.

I may have mis-spoken...but they are on their way out.
In addition, we get NOTAMs in our flight releases that talk about unmonitored NAVAIDS all the time. But who really checks NOTAMS?
FAA plan calls for ILS phaseout starting in 2015
By John Sheridan / March 2006
Released last month, the 2005 Federal Radionavigation Plan (FRP)–a joint
production of the DOT, DOD and the Department of Homeland
Security–provides a useful guide to what air navigation will be like
between now and 2020. Of course, federal crystal balls occasionally can
be cloudy, especially when they peer 14 years into the future.
Nevertheless, since its first publication in 1980, the biennial FRP has
given aviators a reasonable picture of what the future will bring,
provided they accept that nothing that far ahead is cast in concrete.
The basic tenet of the plan is that in the near future the airspace
environment will be satellite-dominated because GPS works well and a
satellite system would allow the federal government–primarily the FAA–to
gradually divest itself of the heavy financial burden of the thousands
of terrestrial navaids it operates today.
Currently, there are around 1,300 NDBs, 1,050 VORs, 1,025 DMEs and 1,275
ILSes as well as marker beacons spread across the National Airspace
System (NAS), along with an unspecified number of radars, airport ASDEs
and ADS-B stations that don’t properly qualify as navaids.
Gradual System Phaseouts
Other government departments also operate navaids in the NAS. The DOD
has several dozen of its own VOR/DMEs, Vortacs and Tacans–the latter two
of which include civil DMEs–while the U.S. Coast Guard runs the nation’s
29 loran stations.
Insiders expect NDBs will be the first navaids to see cutbacks. Already,
of course, the FAA has withdrawn a large number of NDB procedures, and
the agency will progressively decommission transmitter stations until
all that remain are an unspecified number serving Alaska, offshore areas
such as the Gulf of Mexico and what the FRP describes as “international
gateways.”
VORs will follow, with a gradual reduction of facilities as GPS/WAAS
and, particularly, LPV procedures become firmly established. But a
minimum operating network of VORs–probably 300 to 400–will remain
through 2020, primarily as backups in case of GPS failures or
interference. (Interference doesn’t necessarily mean accidental events
or intentional jamming by the nation’s enemies; under the FRP, the DOD
is allowed to conduct GPS jamming tests in the NAS to counter those
enemies.)
On the other hand, DMEs will gradually increase as low-power units will
be added at several ILS locations, and others will supplement coverage
in certain terminal areas and en route altitudes–suggested elsewhere as
being “above FL180”–to provide continuous GPS Rnav backup service.
The phaseout of Category I and localizer-only ILS is scheduled in the
federal radionavigation plan to begin around 2015, coincident with the
expected introduction of the WAAS-based Category I GNSS landing system
(GLS), along with improvements in the GPS satellite constellation.
One ILS will remain at every current ILS-equipped airport for backup
purposes. All Category II and III installations are expected to remain
operational until at least 2020, which may subtly underline the agency’s
current uncertainty about the likely introduction date of their
satellite-based replacements.
Many insiders feel that loran, meanwhile, could remain an ideal GPS
backup.

Ummm, I forgot about that lovely, warm, glow-in-the-dark flavor. And
don't forget the anodes starting to develop that rosy glow when you are
pushing hard on a long RTTY transmission.
OK, never mind.

I guess fantasy suits some people but to me, life, sex, and flying are
not spectator sports.

Ha yes the "good old days". There I was setting in the dark nav compartment with my trusty APN-9 glowing it's warmth and the signal of a master and slave wave from very distant places.
Hmmm What's that smell?
Oh Shit!!! It my trusty APN-9 is on fire!!!!!
My quick pilot/navigator reflexes turns off the trusty APN-9.
Captain: "What's that fucking smell back there?" "APN-9 you say? I told you the fucker is no good! Don't touch it again! " Under his breath "God damn navigators, their bound to kill me yet!"
Oh well I still have my nice and warm glowing radar altimeter. Hug - - - Oh shit!
Captain: "I told you not to touch that damn thing!!!!!"
Me: "Ah Skipper, do you have Gander on the ADF by any chance?"
Captain: "I'm the fucking CAPTAIN idiot and no."
That night the navigation gods were kind to me and put Venus, Polaris and Betelgeuse in just the right spots, for me to steer by and my spring operated sextant pass the angles to me though cold soaked in its mount.
"Give me a good ship - filled with micro chips - and a star to steer by. GPS by God!!!!!!!!!!!

As in.... a PAIR of 4-1000's. Or a GATES... with a 4CX5000
Or...a pair of 3-500's as... drivers.
Sorry to the YAK List for the post about a non-flying topic.

Yeah, those were the days. Line up the pulses, read the TD, and look for
the intersecting TD LOPs on the chart. It made navigation so easy you
didn't really need a navigator any more.

You know, it takes a lot to make me laugh out loud. That one did. Thanks!

I'll bet you two used to do down to the drug store to check the tubes in your television too right?

Oops.... wait a second... so did I.
Speaking of Loran A .... er, ah .. now Loran C. I heard that the FAA was thinking of putting more emphasis on Loran C and were planning on sinking "serious" money into the system upgrading it. The idea being that us airplane folks would then soon be offered an actual Loran-C // GPS Nav Aid... both in one box. Kind of like an Embedded GPS Inertial NAV system, this thing would use a KALMAN filter to blend GPS L1 signals with Loran-C thus creating a system with accuracy approaching or even exceeding GPS WAAIS, or at least... that's what is being claimed.
Anyone else heard this rumor?
