R-800L1 radio question

[Saint19]

Hi all,

 

I'm not understanding the ADF and NDB stuff. I'm trying to get a fix for a radio beacon. But when I try to put the frequency into the R-800L1 radio for the outer marker at Krymsk Airfield at 408.00Khz, I can't. The lowest number on the left side of the dial is 11. The highest is 39. How am I to input the numbers?

 

I can find it on the ABRIS. But I was trying to learn how to use the ADF system. Any help is greatly appreciated.

Um, the R-800 is a communications radio and the ADF is a navigation radio. You can't use the wrong type.

 

The ADF is tuned using the 1-8,9,10 channel knob on the right horizontal panel by the blue autopilot buttons. The channels are presets defined by the mission/LUAs.

[Saint19]

Thanx for your reply. However, the manual states that the frequencies are set using the R-800LI.

 

"R-800L1 VHF Radio Control System The R-800L1 is a VHF-2 command radio system. The radio system is turned on using the VHF-2 (“УКВ-2”) switch on the right panel. This radio can be used to communicate with other airborne units and provide reception of ADF signals."

 

Further down it states...about the ADF switch on the radio.

 

"4. “АРК” (ADF) switch. When this switch is moved to the up, on position, the radio is used for automatic direction finding (ADF). The radio compass antenna is then connected to the R-800L1 radio receiver, and the receiver controls radio compass antenna direction (this in turn controls direction of the HSI RMI arrow). The HSI RMI arrow will now point in the direction of the transmitter with the frequency that is defined on the R-800L1. [LALT + LCTRL + A] A complete list of available ADF channels can be viewed in the Automatic Direction Finder (ADF) ARK-22 section of this manual."

This is the key point. The ADF can be slaved to the R800 as the manual states, but that doesn't mean that you can tune in to NDB's using the R800 (since, as you discovered, NDB's lie outside of the R800's frequency range). So, what's the point of slaving the ADF to the R800? Well, any time someone communicates with you over the R800, the ADF will point in their direction. So this is useful for keeping track of wingmen (or, potentially, any other aircraft or any object transmitting over the selected frequency). It's quite neat to see this in action while in a flight of 4 Ka-50's; slave the ADF to the R800, and then order the flight to do something. Then, as each wingman replies to your command, the ADF needle will point in the direction of each helicopter in turn. Or, in case of emergency, you can get the direction of a FARP or airport simply by speaking to the tower.

Ah...I see. Excuse me if I didn't seem appreciative. I am. I'm just confused about it.

 

So how do I navigate using only the ADF? I was finally able to hear some form of tones "morse code". But I don't understand how to use the ADF. I guess I'm just not understanding the manual. Thanx to both of you for your help.

 

...nevermind I see it. I guess you have to set the ADF to Compass mode.

to navigate with adf i use the chart on right wall to figure out which channel to set dial to on ARK 22 (6-70 manual). Choose the right mode though - i think if you are hearing the morse code then you are on the antenna mode (page 6-71). You want to be on Compass mode and then either refer to your HSI dial or shoose ARC mode on abris and follow red arrow to airfield.

 

“АНТ-КОМП” (Antenna – Compass) ADF mode switch. This switch allows you to select either “АНТ” antenna mode or “КОМП” compass mode. When in “АНТ” mode, the ADF provides you the NDB audio signal as a Morse code. When in the “КОМП” mode, the ADF provides you RMI steering data on your HSI and ABRIS HSI. [LALT + LCTRL + []

Here is a neat link i used to understand navigation with ADF/NDB when i was trying to learn it: The main thing is to get it on your HSI and go from there.

So how do I navigate using only the ADF?

 

This is very tricky and often troublesome in DCS:BS. Since you only have 8 flight ADF channels and of each an inner and an outer setting you only have 16 ADF frequencies programmed into the aircraft before the mission starts and there's no way to change those 16 while playing.

 

Generally the inner/outer frequencies on a channel are logical "pairs" such as inner and outer NDBs at an airfield but there is no requirement that they be.

 

As far as using the ADFs for NDB navigation, it's just a matter of tuning the correct channel/I-O, being in range to the station, and setting the ADF system to "compass" mode. Antenna mode is to listen to the morse code identifier to make sure you have the right station.

Cool, thanx man. I think I've got a much better understanding of it now. Much appreciated.

I can't get the ai choppers to respond to my calls so I can use the HSI direction finder..

 

I tried mulitplayer, single player, and assign ai choppers to tasks and get no response.. I think I tried every frakkin settings possible.. on every radio control..

 

Note: until this time I was able to contact ai helos in missions in the past.. but it has been a few months since I did communicate with ai helos and did get reponses..

 

I just cannot figure out what went wrong trying this now..

I have been flying often but only with live pilots online..

 

thanx,

I don't know if the AI/tower actually "transmit" when talking to you. But they might. You'd first have to be able to have a conversation with them. You have VHF2 powered on, intercom to VHF2, 127.50Mhz, emergency transceiver mode off?

like I said yes, to all..

tower does communicate ai helos are not..

[Frederf]

I wish there was a "transmit" button working even if there is no in-game voice chat for DCS. At least you could hold this down and the RMI needle would move for human-human multiplayer.

[Ramstein]

Hmmm,, I was looking at the aircraft in the mission I am working on and forgot how to make them part of my flight.. this maybe my current problem..

I will go look again and see what I messed up..

[Ramstein]

I looked, as far as I can can tell there are in my flight, how can I absolutely tell?

[Frederf]

I would try one of the missions that come with the game for testing the. It is not good to have too many variables at once. Make sure you can command your AI wingmen in a known "good" mission and then you will know if it is the unknown quality mission is the problem or not.

[Ramstein]

I tried with several missions.. I could not get a radio response from my ai on comms..

 

I give up... mostly,, could somone please upload a mission that will work with the ai comms...

 

thanx..

:joystick:

 

update: I think I got it sorted,, I now see how to add wingmen that respond to orders.. I must have went brain dead on al this,,

 

thanx, I went back and watched a training film too and opened some other missions..

 

but, the AI are stil dumb as hell,, well not that dumb, but dumb....

so there's no way you can dial in a frequency for a NDB that's not in the pre-set 8 channels? Also some of the NDB's on the map are at lower frequencies than it is possible to set on the R800.

No, I dont believe so. It would appear the ground crew would set up your desired frequencies prior to the flight! Thats the beauty of a Russian helicopter sim, reminds you its not a Cessna,with Dial an NDB frequency;)

 

The complete list is in Scripts/World/Radio/beacons.lua.

 

All the frequencies are listed. You can not dial them into the R800 and slave it to the ADF (ARK-22)

 

The file at; \\Scripts\Aircrafts\Ka-50\Cockpit\ARK\ARK.lua script for ADF .

This lists the 8 presets, but they are preset at the respective frequencies. There is probably a way of re-assigning the presets, but you would have to edit the lua prior to mission!
