I'm not sure I follow here - how would you activate a jamming device like a landmine, an RF missile is passive, i.e. not emitting anything (other than a radar signature admittedly) to trigger a device and even if there were a way of doing it the missile is unlikely (incase of hellfire not possible) to attack co-ordinates that were in some way spoofed as the grid reference is only a guide to the rough area of the target RF identification is used to find the target itself.
In any case an RF jammer has to be with what you are defending as all it is doing is emitting noise on the frequency in question making the dissemination of intelligence impossible which requires high power output to cover this remotely would use huge amounts of power.
In the case of missiles then the launch platform knows whether the GPS signal is reliable if if not would gain its coords from inertial nav.
This jammer working on CA (course aquisition) GPS signal and not the encrypted P(Y) channel anyway.
Bear in mind that spoofing the CA code is a defence mechanism that can be activated onboard the satelites in the first place!
There's no real need to adapt Hellfire - you could simply use Semi-Active Laser Hellfire rather than RF Hellfire.
In any case providing that the initial start position signal wasn't jammed (i.e. up to 8km from the target) as (correct me if I am wrong) RF Hellfire uses GPS to give its start position from its launch platform then uses Inertial Navigation to its target.
As Hellfire is predominantly anti-armour, the likelihood of anyone jamming GPS from each tank is slim - firstly the power required is fairly high as Hellfire has an 8km range; secondly it would be tactically unsound as it involves active jamming, hence giving away your position and as the poster states would be a target for RF seeking weapons.
Given the reliabilty factor inherent in PC use today isn't it a cop out to suggest a reinstall as anything but the first option?
The real problem is that the people answering the phones aren't (usually) trained in any sort of fault diagnosis - only punching symptoms into a knowledge base and regurgitating answers. When past experience shows that 99% of suggested reinstalls cure the problem for any given symptom and the fact you are essentially dealing with call centre operators who need to get you off the phone and the next customer on, its inevitable - so why the drama in giving backup cds? Surely this saves the company in the long term!
