ADF (Read 14642 times)

	Good afternoon, Wonder if anybody else is having a difficult time tuning NDB's. For some reason I cannot seem to get the ADF to pick-up NDB's. When I tune an NDB frequency in the ADF radio I do not get any indication from the RMI. Pilot error? Perhaps this is a known issue? Have others also experienced this? Jeffrey Whitaker

	Right now I checked my ADF radios and they are working fine. I suppose you have electrical power onboard. If so, please make sure if the ADF/VOR selector knob [4] and/or [7] is/are turned to [ADF] instead of [VOR] (see image below). Hope this help. Pinatubo.

	How to tune the ADF Check out the screen capture. I have circled three items. One in green is the switch that turns the unit on and selects various modes. Use the ADF position. The tuning knob has a few selections. The outer ring selects the proper band, while the inner knob selects the frequency. In this example I have selected the Georgetown NDB - frequency 323.0. You can access this information from the FSX menu in World/Map, or from approach plates. Using mouse over and left and right buttons to move the knob you select the proper frequency. As you get close to the proper frequency you can check the exact frequency from the window that appears when you stop pushing the mouse button (in orange circle). �As you get close to the proper frequency, check the meter [this shows full strength] at the top of the ADF control panel (also in orange circle). You have to be in range of the NDB to receive the signal. Then select the audio switch and identify the code. Lou Uploaded with ImageShack.us

	LOU, Thanks for clarifying ... actually, I don't use this option to "flight tips" in FSX, I think that's the name.

	In my case, in FULL SCREEN this window doesn't appear too... it seems to be due to DX10.

	The left and right ADF control heads are located on the overhead panel. Lou Uploaded with ImageShack.us

	My bad, I forgot this was about the 727... Here is the 727 ADF control panel tuned to the Georgetown NDB near KDCA. Notice the signal strength is less than the 707's. Lou Uploaded with ImageShack.us

	To avoid this ghost window with DX10, Captainsim team could modify this gauge and add a switch to show frequency during a few seconds ! Take a look at the Etendard IV ADF:

	Mric29, I like that window. This is not a CS thing, but a FSX hangover. I agree it is a royal pain in the butt to try to tune the ADF - and in the old 707 and some of the 727's it too was a pain in real life. The digital tuner on later planes were a lot better. Still, you always have to identify the code to be sure it is the correct station. Lou

	Thank you LOU, it was my first animated gif! You are not wrong but who will fix this DX10 bug, Microsoft? I don't think so... I call Bill Gates and I tell you.

	Does the "gain" button and "BFO" on-off switch have some impact in tuning?

	Kjetil, Good question! I have not been able to receive the audio from the VOR or ADF. I use the meter to see if there is an indication of signal, but the Gain or BFO does not seem to do anything. The distance for receiving a LOM NDB seems to be around 20 miles. Try this; at a commercial airport with a NDB. While on the ground at the airport, tune in the NDB and see if you get an indication on the meeter and in the ADF instrument. Remember to flip the switch on the ADF to the ADF position. Lou

	The thing that pops into my mind is noise adjustment. Like tuning a naval surface radar more or less sensitive to adjust it in calm or high swells. Maybe it is in real life to wash out the worst noise in a crowded airport like London Hethrow or O'hare in Chicago. I think it will be a lot of other signals that would interfere with the ADF-tuned signal. And on the other end of the scale, the gain could be adjusted different at Bermuda where I guess it is less signal noise. Or maybe I am totally off course here.
