I couldn't watch the video for some reason.
It should show up on the TA NARROWBand before it shows up on the SA BroadBand... and if you don't have your contrast set right, you won't see it on the NB.
The BB performance of the TA is not so great, in the mod, and according to my information, in real life as well. Many quiet targets won't show a BB trace on the TA, depending on the acoustic conditions, and this hasn't been changed in our mod (the TA sensitivties were already set pretty good...).
