Morning (PDT) all,
 
Guy on TNE FF&S Mk I Mod 0 p. 53 second column is a section covering Radio, Radar, and Active EMS Direction Finder (DF). According to the section adding DF capability to RADAR at 2 times the price and AEMS at 1.5 times the price. At TL-6 stand alone DFs are available with the same mass, volume, antenna size as a radio of the same TL, however they cost twice the cost and the power requirements equals the volume at all ranges and tech levels. The PEMS incorporates radio and radar direction finder capabilities.
 
My guess is at TL-10+ the PEMS is used for direction finding which makes no change to the packages with a PEMS installed.
 
Another guess on my part is none of the TL-9 packages are capable of being used as direction finders.
 
Is my guess correct that TL-9 sensors are not capable of direction finding?
 
My first suggestion would be to add the DF option to the RADAR suites for the small and medium sensor packages which would change only the price of the two systems.
 
The second suggestion would be to add a stand alone DF to the military packages which affects just about all the characteristics.

My work and the listed value in the T4 QSDS 1.5e Standard Sensor Systems Table on p. 10 for a fixed antenna match without a jammer installed.
 
The next update will be the TL-10 Medium Military package with a J2 jammer installed which I’ll post on 4/29/15.
