The information was taken from this (http://www.battlefront.com/discuss/ultimatebb.php?ubb=get_topic;f=41;t=000794) thread on the BattleFront Forum.

Initial question was why does the mast break at 63ft depth (PD depth) ...

Page 510 of the electronic manual (In the printed version it's: Section 13: 688(I) Stations 13-24) - the section that covers the 688i RADAR....

688(I) RADAR STATION [F3]
Submarine radar should be used with caution and only when the situation mandates its use. When you use radar you communicate your presence, your bearing, your proximity and who you are if the other platform is equipped with EW or ESM equipment.
MARKING CONTACTS WITH RADAR
1. Ensure that Ownship is at 54 feet or less and moving at 8 knots or less if the sail is submerged.
2. Click RAISE in the RADAR MAST Panel in the upper right of the station to raise the mast. The RADAR READY light glows continuously when the radar mast is extended and radiating.
3. Set RANGE SCALE as desired and set the RANGE RING toggle switch to ON if range rings are desired on the radar display.
4. Contacts show up as brighter orange spots on the display. Click on a contact to select it with the Bearing-Range Cursor or click and drag the cursor to center it on a contact.
5. Click MARK to send the contact’s bearing and range to TMA and the Nav Map.
-> Note: Radiating while the radar is submerged destroys your radar.

Keep the sea state in mind when using the radar as well. If a wave washes over the radar when it is radiating, the radar will be destroyed.

Was running a QM ASW Barrier search last night with my 688 (I) on surface I had a ESM bearing fix on a frienly Trawler and had my radar on but I could not see him on radar even turn truth on to see him.
does gamma settings have any effect on radar targets?
I am running patch 1.03 beta and LwAmI v 3 beta realism mod
Never cheked range but he looked close enough I though I should see
Him?

Gamma settings could effect just about anything if they're bad enough. Do you have trouble seeing anything on the MH-60 or P-3's radar? They all pretty much work the same; they display X's on the contacts. I do think its kind of odd that you had an ESM hit without being able to get him on radar; but then again I might be underestimating ESM range when the sub is on the surface.

Molon Labe,
I think I changed gamma from .89 to .8 in DW ini file. what do you have yours set at? Will fly the MH 60 and P3 quick mission and see if I can
see some radar targets I know I have seen the little x's on PPI before
Or run Bill's We dive at dawn and check my radar
Thank's

Quick test of my 688 (I) Radar works fine leaving Harbor in Bill's
We Dive at dawn Using 1.03 beta LF AMI ver 3 beta
