• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

In addition to the States experiencing 911 disruption, this also caused interruption in service to the interface used for transmission of EKGs to hospitals from EMS in the field.

Incorrect. The outage was in fact caused by induced currents during a geomagnetic storm.
Back in the old navy they were called "sids" severe ionospheric disturbances.
I worked a navy receiver site in the N A desert and we tuned about fifty stations on all different equipment on a lot of different freq's.
When circuit control started losing stations we (all two of us) would put stations on speakers and listened to them go silent.. Nothing for us to do but sit and wait. Usually the side band would be the first to come back and then the rest. Busy getting them tuned in and hitting the CW key to let circuit control who they could have back.
Satellite communications made us all obsolete and all that equipment is probably buried under the sand now.

The location of the effect depends on local conditions, including underground electrical and magnetic fields. The current coronal hole stream caused three distinct events as it arrived - the ConEd fire in NYC, the 911 outage, and a transformer explosion in Louisiana.
