Fonsini - absolute hoop I'm glad to say. There were problems with spectrally impure RADARs in the early days but the addition of YIG filters solved a lot of those issues. By the time we were on Stage 2 RADARs any issues were well ironed out. The early issue wasn't with F16 RADARs by the way, but with more 'agricultural' spectrally impure RADARs.
The EW/ECCM features on Foxhunter were pretty good when looking at other types flying on TLP. That said we never really knew what we all had 'hidden up our sleeves' for when the real shooting war started!
