ADF Question.

Post by Daneng »

How can I enter a ADF frequency ending with a decimal digit ( ex. 399,50 Khz ) into the Bendix King KR87 ADF ?
Most ADF frequncies in Europe are like this .
Many Thanks.
Dan.

I think I recall reading somewhere that you can change the frequency to a .5 in the Shift+6 menu.

I found a way,
If you use Plan G navigation plugin to FSX you can right click on an NDB on the map, and 'set NDB freq to NAV radio' and it will tune NDB's that have the decimal frequencies.
I explain in my video here:

Thank you Torwale8 and Mantock.
Problem resolved now by adding the line AutoTuneADF=Yes in the FSUIPC.ini file .
I will try your solution as well Mantock.
Regards
Dan.

Yes, up coming fix will add ability to tune .5 into the 2d panel. The unit itself as with most though don't have this ability and its an FSX bug that you have to tune exactly rather than near the freq.

Would this be a reason to break from the real world systems? After all, the 172R does not exist outside of FSX, so could we allow a .5 tuning in the virtual cockpit? Just wondering ... maybe the 2d panel idea is better.

I prefer the 2D panel solution and leaving the ADF unit as is. This is the actual real world function of the unit, there is not an ability to tune decimals. Having the work around be available from a sim menu seems like the most logical way to strike a balance between reality and desired functionality.

FSX w/Acceleration and tons of add-ons.

Agree, sounds like the best compromise...

Hiya,

Same "issue" is ofcourse present in the Piper.

Was wondering how this work in the realworld? If you want 388.5, do you tune 388 or 389?

Well, I don't know if there are some 'official' practices, but I'd just choose whichever works better! :) It doesn't matter. ADF receiver's 6dB bandwidth is usually around ±2 kHz or so, which, overly simplified, means that if mistuned by 2 kHz, the receiver pics up about 25 % of the signal strength it would pick up if it was precisely tuned to the frequency. If the selected frequency is off by only 0.5 kHz, its received strength is surely much higher in any sensible receiver design.

Perhaps if someone (krhm... A2A) were to simulate a proper ADF, there could be a hidden auto-tune feature that looks for FSX/P3D NDBs in range that are within about ±4 kHz of selected frequency, and would internally tune the 'proper' frequency automatically for simulation, but the offset between the actual and selected would affect the S/N used for needle dynamics. Not sure how difficult that would be though.

Its old school technology so either one. Think of it like turning your fav radio station, theres a wide band that you can pick it up on you just get somewhere in that band and your listening to the station.

Any change for a working ADF receiver in the C172 and piper? :roll: 8) Think you would make a lot of European users happy.

Hi Marcel,

Have a look at the last 2 posts in this PPRuNe NDB frequencies thread. That pretty much sums it up.
