What's your opinion on the precision of the knowledge of the brit rail & infrastructure operator about their systems ? 'Grandfathered' systems ? Using the VHF/UHF handheld radios inside the ambulance van ? As in 'Jones, we need more plasma now'. Then: 'Jones, we don't need it anymore'. You can imagine that the real details are hard to obtain since they incriminate certain manufacturers. I for one have a gsm handy that seems to cause computer monitors to show lines and amplified speakers to go crackle-crackle when used near them or their wires (<1 meter or so). And I always know when someone is calling me because the scope leads pick up the handshake before the first ring (up to 3 seconds before) and my Fluke meter beeps if the phone is on the same table where it is. I can see the packet bursts at maybe 1/2 vertical division.
