Fired up a spectrum analyzer as POTUS motorcade went by. Definitely wideband jamming from lead WHCA vehicle. (& it unpaired my BT headset)
I had been skeptical of reports that they routinely use jammers, but there was strong wideband noise from abt 700mhz to beyond 2.5 GHz.
VHF was quite clean, which is where most sec svc traffic is.
... it seemed to be about half a block.

ultra-wide-band SDR to the rescue? (60Ghz MIMO or bust!)
