Damgarten RSBN

[Ian Boys UK]

The F10 map says the RSBN for Damgarten is 32, but in the L-39C it is 20 and on the Mig-21 it doesn't work at all (yeah, I know, it has it's own systems). But it should be right on the L-39?

[Tarres]

There is a bug in the lua file for Damgarten RSBN, between the frequency and the assigned channel.

I think it’s reported. For now the RSBN that works is, as you say, channel 20.

I did the RSBN for the Mig-21, and desiganted as 32 for the Damgarten. Example from the file:

 

Since we talk about this airport, does anyone know the location indicator code? I couldn't find it.

As far as I could see, Damgarten seemed never to had an ICAO code or something like that.

About the channel, in fact in the Beacons file, the frequency is 820 MHz, which corresponds to the channel 20. I modified it in the file to 832000000.000000, and it works fine at channel 32 (RSBN and PRGM), but strangely the localiser seems to be wrong. As I needed to set the bearing at 72 instead of 79 while being aligned with the runway. I ran a test with channel 33 (833MHz) for the PRGM, and the bearing was correct. 

Here a screen with PRGM at channel 32.

This solution works for the L39, but not for the Mig 21. He never shows any reaction to the channel 33. Same with channel 32 PRGM won't work at all.

Mig-21 is not connected with the Beacons.lua file, but only with the corresponding "R_NAV_data_MapName" file, which is located here:

...\Program Files\Eagle Dynamics\DCS World OpenBeta\Mods\aircraft\MIG-21bis\Cockpit\Systems

This is the file I've created (for Germany).

Indeed, I've understood that. I was just wondering why the Mig 21 didn't catch the PRGM despite the fact it was tune on the same channel as the RSBN.

Mig-21 RSBN (rotating radio beacon, a rangefinder) and PRMG (landing system) are both on channel 32. This is specificed in R_NAV_data_GermanyCW.lua file. You say when putting RSBN Mode Selector switch to Landing mode, it doesn't work? It should, there is nothing more I can do. Its all there in that file.

L-39 is based on beacon.lua file, which you have already modified and tuned it to channel 32 and you said it works. But as @Tarres said there is a bug in the beacons.lua file. @MAESTR0 can you please check it out? And can you guys add airports names into quotation marks of "display name", they are mostly empty now (1st line of code):

display_name = _('');
beaconId = 'airfield84_1';
type = BEACON_TYPE_RSBN;
callsign = 'PM';
frequency = 820000000.000000;
channel = 20;
position = { -101589.343750, 52.000052, -576051.812500 };
direction = 0.000000;
positionGeo = { latitude = 53.432656, longitude = 11.784527 };
sceneObjects = {'t:-1113250655'};

I will run tests on ohter airfields. I know you made all what you can, maybe it's the Mig 21 who has some issues. For the L-39, indeed it works, but as told while landing on runway 07 (79° bearing), the localiser was offset with the runway while using the channel 32. Seemed that it was using the RSBN as loc.

For the question to @MAESTR0, I've posted a Beacons file, where the informations are completed, and several ILS updates where made. Only issue I had was on Frankfurt where the ILS on runway 07L-25R, I even tested it with the original file, with the same issue. Maybe you can test it, if you have the original file to confirm the bug. I made a video from the behavior.

And if you want, you can load the Beacons file there, I just updated it with channel 32 for Damgarten.

I just run a test flight and added smokes on the Loc, glideslope and RSBN, and I can confirm that in the L39, when RSBN and PRGM use the same channel, in Damgarten for sure (had to be confirmed on other airfields or maps), the loc needle deviates through the RSBN as you get closer. Bearing was set to 259° and the perfectly aligned with the runway. I had the same issue on the other side.
