Radio depth
 

Issue want to correct for forthcoming TMO update (if possible) is should be able to send contact reports at periscope depth(from what understand fleetboats could and in sim already receive messages at periscope depth) not have to go to 35 ft or so exposing sub.


Which file(s) do need to look at? Have not located them thus far.

I've been wanting to do that also. The subs could actually "talk" deeper than PD later in the war, so I was wondering about raising the level of the 'antenna' maybe, but haven't gotten around to experimenting with it yet. I haven't looked to make certain, but I think it is tied to "radar depth", aka: "Snorkel depth", or, if modded further - aka: "Decks Awash"... :salute:

I agree. I would add length to the radio antenna such that it would break the surface at whatever depth you deem appropriate.

Why not make it match the periscope length. Then you can radio from PD.

I've changed it...somehow. All I can remember is that it is not something simple or obvious.


As for the radio side of things, this is where my experience comes in. Fleet boats had the following receiving radio sets:


RAK-6: This set covers the VLF, LF, and MF radio bands from 15 kHz to 600 kHz


RAL-6: This set covers the MF and HF radio bands from 300 kHz to 23 mHz


RBH-2: This set covers the MF and HF radio bands in frequencies from 300 kHz to 1.2 mHz and 1.7 mHz to 16 mHz.


The lower frequencies (VLF,LF) would be data only in the form of morse code, while the higher frequencies (MF,HF) would be voice circuits. As such receiving radio signals while submerged would only be possible on lower frequencies, with VLF being the best being able to penetrate to a depth of 40m or 131ft.


Now the transmit side of things:


TBL-5/6/7: Can transmit voice (75kHz-600kHz, 2mhz-18mHz) and data (175kHz-600kHz, 2mHz-18mHz) in the LF, MF, and HF ranges.


And the final puzzle piece, the antenna:

Note the Transmit Antenna and the separate Receive Antenna. In order to transmit and be received, that antenna needs to be out of the water. There are of course other antennas onboard but those are for LOS comms, basically short range.

Surely it's a sim file setting... at least, I ~hope~ it is... lol - thanks for the info ETR3(SS)! :salute:

the antenna length is in a sim file. C:\Ubisoft\FOTRSU 1.46\Data\Library\USSubParts\Sensors.sim

and stop calling me Surely.

Surely is the one sitting behind you, with the pleated, short skirt, funky jacket, and saddle shoes with Bobby socks...

I have that file open in TMO. I do see a radar but no radio antenna , unles labeled something else. I see where on SensorType the radio antenna is an option along with visual, radar, etc

obj_Extensible has the radio option.
Only the German boats use it.
Not saying you can't cheat and do a US Sub that way.

I'm working on what it was I did to change it.

you are correct.
please edit or delete your response as i have done to mine so that there is no confusion moving forward.

Still looking into the how I did this. I'll add this bit of info though, the game considers you either surfaced or submerged with no in between. Once flagged as submerged the radio is disabled along with the diesel engines, unless you have a snorkel equipped. New options become available once submerged as well like emergency surface, deploying decoys, and silent running. There is another controller for when the deck crew moves below decks that doesn't coincide with the surfaced/submerged flag. Using my Skipjack as an example, you can be "submerged" at 32ft with the bridge still manned until 35ft!:o

Thus far I've tried changing settings in the sim and cfg files to no effect. I want to say it's either 3d model based or node location based, which one of either one is anybodies guess at this point. I'm going to try to recreate one of the nuc subs this weekend and perform more rigorous testing to see if I can uncover an answer.

I've been looking at the US subs in FotRSU, and none of them have a "real" radio, only a virtual one, attached to a virtual antenna, which visually is rendered as a part of the sub, not on its own node... Snorkel depth, or radar depth is when you can use the radio in FotRSU, but changing that would not be the way to get the radio to work, since they the radar would not work... it uses the underwater controller for on and off... in FotRSU, that is. A nuc, it wouldn't matter...

i can understand this explanation being reality....it is very UBI.

You did use a U-boat Snorkel.
