Let's see your manual targeting mod list -

[I'm goin' down]

I have tried lots of mod combos. I have three different game set ups on my computer, and with recent mod additions, they are all good. Here they are:

Map contacts are enabled.

Setup No. 1

Trigger Maru Overhauled 2
TMO Update 20 to 21
RSRDC TMO V502
RSRDC V5xx Patch1
Fixed CD sonar RSRDC
Fixed Zero Bomb Load RSRDC
IJN Radar Fix for TMO v1
TMO Visuals for RSRDC
SCAF for RSRDC v 502 2.0
Max Optics IV for TMO 2
Stock Map Icons
TGT Dials for PK Fix TMO (Easy Aob)
USS Barbarinna Fooskin Combo Custom
Nav Map Make Over v. 2.0
Captain Midnights CBS News Sound Mod
EAXsoundsim with Webster's Manauever TMO
Extra Allied nvaval bases for SH4 + UBM + TMO1.7
3000 Yard-Meter Bearling Tools (1280 x 960)
Damage caused by fires (TheDarkWraith)
#4 PE4 Ship debris Sh4 with bodies
New Large Lifeboats

(Alternative set up: If "no map contacts" is enabled, delete Stock Map Icons and insert nisgeis' 3d TDC. This mod slows game play as plotting attacks take longer.)

Setup No. 2

Webster's GFO Mod v1.1
Webster's New Orders Bar Menu for v1.5
#2 Submarine spash and roll pitch mod with
#3 Corotio cameral fixes bugs for the uboats
#4 Warships retextured
#5 optional loading screen
Extra Allied nvaval bases for SH4 + UBM + TMO1.7
Damage caused by fires (TheDarkWraith)
Nav Map Make Over v. 1.1
New Large Lifeboat
Real Guns Sound Mod
USS Barbarinna Fooskin Combo Custom
#4 PE4 Ship debris Sh4 with bodies
Optical Targeting Correction (new mod)
OTC US radar from Start (new mod)
OTC German PPI Sceen (new mod)
3000 Yard-Meter Bearling Tools (1360x)
Carotio's Intercontinental Radio Pack
#1 Real Environment mod install
Webster's GFO Patch for Real Env #1
Stock Map Icons
Military Morse Code keys
Carotio's SH4 TrukCoralHarbourCityLocations

Alternative: If map "no map contacts" is enabled, determine speed by calculating the time it takes the target to cross the specified periscope bearing (I have yet to attempt this.), or use the 3D TDC if it does not conflict with OTC. If required, apply Capn Scurvy's tutorial on calcutiing target's course and speed with map contacts disabled or use the stand alone Sonar Tracking program.

To be added:

RSRDC v1.4 (per Webster if you use GFO with lurker's campaign mod)
Harbor fix (if such a mod exists?)

Setup No. 3 (for UBoats but this set up also provides for American boats in PTO). This is Operation Monsun, Operation Monsun Environmentally & Graphics Upgrade (OMEGU) and Kreigsmarine Interface for UBoats (KiUB.)

OpsMonsun V705
OMv705 to 720
OMv720 Patch5
OMEGU v300
OMEGU V300 Patch7 pkg
OM Plot V415
OM Harder Escort L2
OM MultCmd Keys
Karamzov
AOBF 19-9 Res
OMEGU English
KIUB English
OM SH3 Command Keys
OM Med Env
Green Lamp 2
Carotio's InterconinentalRadioPack
3,000 Meter Bearing Tool (1360x)

(Option: RSRDC and RFB.) I have just started using this mod and am still on a learning curve. Apparently it is compatible with both of these supermods. OM/OMEGU/KIUB is an excellent mod.

All set ups: For plotting intercepts at long range, set up MOBO, a stand alone program, on the desk top. This is aaronblood's masterpiece, and can be downloaded in the MOBO forum.

Mod fix request for GFO: Apparently OTC is not compatible with Easy Aob. If the Easy Aob fix for Aob only could be made compatible with GFO and OTC, it would be welcome.

Need help to determine the lead angle? Download gutted's Solution Solver stand alone program. It is a great teaching and learning tool.

Note: Carotio's InterconintentalRadioPack includes the TransAtlantic Radio Mod. The "Pack" includes three German radio stations (one with English war time broadcasts), Paris, Tokyo, Hawaii, Hollywood, NBC, CBS and BBC. It is activated via JGSME, and does not require changing the radio.ini files.
