We are on AMC-18

May 10th, 2017

The five U.S. commercial radio networks who operate their own satellite systems have now been up and running on the new AMC-18 at 105 degrees West Longitude for a month. 105 degrees West is the long-term replacement location for radio network traffic that's been at 139 degrees West for many years. AMC-8 has exceeded its design life and is not being replaced by an equivalent C-band satellite at the same location. 

The five networks - Learfield, Orbital Media Networks (OMNi), Premiere Networks, Skyview Networks, and Westwood One - now have their full complements of satellite-delivered programming available on their new frequencies on AMC-18. This includes all show titles, satellite channels, contact closures, PAD data, cue messages and file-delivery channels - the same ones you are familiar with from AMC-8. 

It also includes programming from syndicators who lease their satellite time from these five companies. A partial list of those syndicated programs is included in our FAQ document at http://www.amc8migration.com/docs/RNUG_FAQ.pdf

May marks two-months-left in the countdown to U.S. commercial radio programing being permanently removed from AMC-8 at 139 West. June 30, 2017, is the final date for all affiliates to have their satellite downlinks repointed to 105 West.

To ease the transition, each network has programmed (or will shortly program) a Fallback Carrier into a table in each receiver's memory. This allows each receiver (whether XDS or Wegener) to find the correct new carrier on AMC-18. Once a receiver loses lock on the old signal on AMC-8 (because you’ve pointed away from 139 West), it will alternately search for the "old" and "new" frequencies for that network until it locks to one. When your dish is successfully pointed to 105 West (and properly polarized),  your receiver(s)  should lock to the "new" signal within 30 seconds to 2 minutes.

An excellent antenna aiming tutorial by Fred Wilcox is available here: How to Re-Aim Your Satellite Antenna

An IMPORTANT NOTE about crosspol interference on AMC-18 affecting MANY poorly polarized antennas.

Spectrum analyzer plots are here (in a PDF) so you  can see what each transponder should look like at L-Band (the outoput of the LNB on your antenna.  

The old and new frequencies for each network are as follows. Remember, in most cases the networks have already programmed these frequencies into your receivers, so you should not need to input them manually:


Old frequency on

AMC-8 at 139W

New frequency on

AMC-18 at 105W

Kalipso receivers do not have a fallback carrier table and must be set to the new frequency from the front panel.

Numbers are shown here with commas for clarity.  Receiver displays do not have commas.

If your affiliate downlink antenna (dish) is in too poor condition to be repointed or is not 2-degree compliant - which enables downlinks to reject interference from adjacent satellites - you are strongly urged to consider replacing it with a new one. Although the networks do not endorse any particular vendors, many of them have requested to be published on a list at http://www.amc8migration.com/Vendors.html
