To all who monitor ARCS for their EAS alerts; be aware that
a change in the carrier is planned. Here is the email that went out to our
contacts:
Ladies and Gentlemen:
On Wednesday, July 9, 2008, at 9:00 A.M., Alaska Daylight
Time, the Alaska SIP multiplex will undergo modifications, the result of which
will be a smaller, though no less effectual, carrier. The changes are
being made to accommodate the departure of “360 North” (formerly
Gavel to Gavel) from the bundle.
The changes to the carrier will cause a brief outage that
will affect all satellite based audio and video services inside the AMC8,
transponder 18, SIP Multiplex including Alaska One, UATV, and ARCS Television,
and the audio feeds for KSKA, KUAC, KCAW and APRN. Please note that this
message is not concerning SCPC radio cannels on transponder 24.
Scientific Atlanta PowerVu receivers that are operational at
the time will receive new parameters automatically and should not need to be
manually programmed.
Should a receiver need to be manually programmed, there are
instructions for the SA PowerVu D9223 and the non-SA DMT 1050 posted at the www.arcstv.org
website; follow the “Troubleshooting” link to the receiver
page.
The new parameters for the carrier are as follows:
Center Frequency: 1093.50 MHz L-Band, or 4056.50 MHz
C-Band.
Symbol Rate: 13.250 Ms.
The FEC rate will remain at ¾.
All Non-PowerVu receivers will need to be reprogrammed
manually; if you are affected by this please refer to the parameters
listed above and consult your owner’s manual for further
instructions.
The duration of the outage will be brief; on the order of a
few minutes, especially for the majority of receivers which are PowerVu.
For non-PowerVu receivers, there will be no way of knowing exactly when the
procedure has been completed, other than to enter the new parameters manually
and wait until they lock on the signal.
A further update of this announcement will be issued when
further developments warrant and details become available. Please reply
with questions you may have about this email.
Thank you for your attention.
