DW Narrow Band station - and SC
 
Do you think it might be possible to swap SC narrow band station with DW station ?

It worked fine in SC. I'm talking about mark button in NB station.
In DW If you mark contact on NB station you can't see it on DEMON station.

Could someone try to do it?

I don't have access to DW now and I don't know how to do it either.

That is correct.

From what I've been told, in DW you will yeld DEMON data only if the tracker is strong enought to be assignable in BB station.

Qppralke 07-11-05 10:21 AM

yes. I wonder if it possible to fix it by copying the files responsible for NB station from Sub COmmand.

Damage display could be potential problem...

It's not "broken", so there is no "fix". That works as designed - no DEMON info from NB.

Let's stay on the topic, please.

It works exactly how it is supposed to in DW :up:

One of the games: Sub Command or Dangerous Waters is broken then. :|\

I'm looking for technical advice on the problem

Renzie 07-11-05 12:13 PM

Sub Command is the one that is broken. DEMON data is derived from broadband data NOT narrowband data. It was a fluke (and a bit of a cheat) that you could mark things with narrow band and see them on the DEMON waterfall display.

What we tried to do with DW was improve the realism...I know it is a bit confusing sometimes, but we thought that the results were well worth it :sunny:

We were animated about this in the BETA phase. There is a section located in fas.org that explains DEMOdulated noise and how it's derived from BB sources and NOT NB. Think of it this way...NB is a set of descrete frequencies that are seperated while BB is a ton of noise produced by the contact.

Typical broadband sources are noise from either the propeller/shaft, flow noise and some propulsion systems (example: steam). Noise from the propeller and shaft is generally at low frequency, meaning less than 1000 Hz. Furthermore, the rate of rotation can amplitude modulate the noise, which can be detected and demodulated to measure the shaft or propeller blade rate.

Narrowband sources radiate within a small band about a particular frequencies, or class of frequencies. Typical sources are the various pieces of machinery found in every ship. For example, pumps, motors, electrical generation equipment and propulsion systems. When specifying narrowband sources, it is important to also specify the frequency at which it occurs.

Very interesting Sonar732.

Since we're discussing the sonar station... I was wondering if the effective contacts noise ( the part that the human ears react to) is already used to help the filter yelding a classification? (or a set of classifications)?

Because sometimes if the TV is on i have to boost the amplifyer to ear it :lol:

Qppralke 07-11-05 01:26 PM

:hmm: There is possible bug anyway...
Take a look at the screenshot from my multiplayer session.
It was taken before first DW patch, so it was a clean installation.

Empty slot is selected and DEMON waterfall is showing data anyway.

Is it going to work if i try to swap the stations between games anyway ? :hmm:

Yes, you can classify with our ears...the old saying that we would still rather do it ourselves comes true.

There are multiple signs that tell our ears what type of contact it is.

THFRO comes partially realistic again :lol:

Interesting challenge but not sure whether the Mark 1 ear-drum is (now) up to it . (The Hi Fi /Rock de- generation )

Tested BB station sound for some Russian surface platforms and can hear subtle difference between different but identical types.
Not sure whether this is a software database model per platform /unit or merely a result of sea conditions, distances etc.

PS. Dont you just love abbreviations - like BSE. or BSA more appropriately.

Still I can talk - SVAK !! (Sonar Visual Aid Kit)

Bellman.

Send not to know for whom the bell tolls....
