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.
