Folks, I have received the following....
______________________________________________________

NOTIFICATION OF GPS JAMMING EXERCISE: HEBRIDES RANGES, 8 to 12 April 2013

Dates.  Between 8 and 12 April 13

Times.  Between 10.00 to 12.00 GMT and 14.00 to 16.00 GMT daily.

Location of jammer.  The jamming aircraft will fly a ground track based 
on the Benbecula (BEN) VOR 275° radial.  The aircraft track will extend 
from 10nm west of the BEN VOR to 60nm west of the BEN VOR

Frequencies.  24MHz bands centred around 1227.60MHz and 1575.42MHz.

Jamming aircraft altitude.  3500ft Above Mean Sea Level (AMSL).

Affected areas.  Interference prediction plots for a Civil GPS receiver 
at 165, 3000, 10000 and 30000 ft AMSL

It is recognised that this trial will have some effects on local 
operations but as always safety of life will take precedence over trials 
activities.  Therefore, in order to reduce these effects as much as 
possible, the following measures will be carried out:

a.  The jamming will only be transmitted in a westerly direction away 
from the mainland.

b.  Continuous jamming will be limited to 12 minutes maximum per run 
with 5 minutes minimum between runs.

c.  Both Benbecula Air Traffic Control and Stornoway Coastguard will be 
informed each day as to whether jamming activity will be taking place 
and when exercises are complete for the day.
