[Scan-DC] Anyone know what freq EZPass uses

[Robert Brubaker]

Thanks John

Interesting frequencies, they all seem to be in the 33 cm ham band.

It would seem, given the way these things work that they could be used
to find stolen cars or just to track where folks drive.  I assume cars
could be polled along any road.

It would be interesting to see if the query burst is long enough to hear
on a scanner.  I live near National Airport  I'll try finding theirs.

  Correct.

  Reagan National Airport  Parking - 903.0000 mhz.
  NOVA Toll Roads - 915.0000 mhz.
  Powhite Parkway - Richmond - 915.0750 mhz.
  Pocahontas Parkway - Richmond - 915.7500 mhz.
  Toll Roads - Chesapeake - 915.7500 mhz.
  etc.

  They are not 2 ghz. applications.

  Don't plan on using it on the Powhite Parkway in Richmond.  The toll
road
management originally, as events since have proven,  negligently
installed
the Smart Tag equipment, which is not compatible with EZ Pass, in a
large
culvert pipe underneath the toll road.  That's right.  It was installed
in a
large drain pipe under the road.  Brillant idea.  No need to build a
separate building to install the equipment...saves money.  The September
rains deluged Richmond and flooded the culvert to its top and ruined all
the
equipment.  But not to worry, help is on the way in the form of only a
few
hundred thousand dollars more of Va. taxpayer's money.  It all can be
fixed
hopefully.  Unfortunately almost two months later it basically still is
out
of order.  But the good news is when it is fixed it will recognize the
EZ
Pass transponders....maybe.  Meanwhile, bring coins.
