Quite Possible but again all are theories as whatever information is available in open source is opposite to his hunch ....
Just as an example: fratricide of Indian Helicopter indicated that the radar of Spider SAM was working properly as it successfully detected and tracked the helicopter as target .... So if Indian were also employing EW ad were jamming "All the Frequencies
including their own" than how their raddars were working properly and why they chose to jamm only that frequency which was used for their own communication .... ???
Its quite illogical (at least for me)
Keep in mind our Jets were not in the vicinity where this incident took place, so there was no reason for the employment of EW by PAF in tha area.
Our blinders were flying on our side of LOC so it could not be case of EW by PAF
I think
