Is this site reliable:https://www.spacelaunchschedule.com/launch-schedule/launch-details.php?id=1416?
For some weeks now, they are indicating the same launch date of October 29th for this launch?

Look at the dates/times on their home page.  Those aren't real, just rough estimates.

FCC filing shows November 6 for the currently targeted launch date.

SpaceX Opens Accreditation for SXM-7 Mission

HAWTHORNE, Calif. – October 6, 2020. Accreditation is now open for SpaceX's SXM-7 mission, which will launch from Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station in Florida. The launch is targeted for no earlier than November.

Maxar Delivers High-Power Digital Audio Radio Satellite to Launch Base for SiriusXM
By: Maxar Technologies
10.14.2020

The powerful, Maxar-built SXM-7 satellite arrived at Cape Canaveral Air Force Station on October 13, 2020. Once on orbit, SIRIUSXM, the leading audio entertainment company in the United States, will use SXM-7 to ensure continuous and reliable delivery of SiriusXM’s entertainment and data services to tens of millions of subscribers across North America. SXM-7 will deliver the highest power density of any commercial satellite on-orbit, sending more than 8,000 watts of content to the continental U.S., Canada, Puerto Rico and the Caribbean, increasing the quality of signal for SiriusXM subscribers.

SXM-7 weighs almost 7,000 kg and will be carried to geostationary orbit by a SpaceX Falcon 9 rocket later this year. The satellite is built on Maxar’s 1300-CLASS PLATFORM, the world’s most popular spacecraft platform, and it is designed to provide service for 15 years or longer. Once on orbit, the satellite will deploy a large unfurlable antenna reflector, which will enable broadcasts to mobile radios, such as those in moving vehicles.

Maxar is also currently manufacturing SXM-8 for SiriusXM, which is expected to launch in 2021. Maxar has previously built a total of seven satellites for SiriusXM, including its first-generation Sirius satellites that were launched in 2000 and its second-generation Sirius satellites that were launched in 2009 and 2013.

Watch the launch on SPACEX’S WEBSITE.

The rendering above shows what SXM-7 will look like when fully deployed on orbit.

Re: Deducing launch date.  Doesn't the processing of a GEOcomm satellite for launch usually take about 6 weeks?  November 6 would be unattainable by that parameter alone.  (Notwithstanding the availability of a reused < 5 first stage.)

Most sites are listing the launch date as “NET November”.

SpaceX’s launch contracts specifically require payloads to arrive 4 weeks before launch. Typical schedule requires 20 days just for unpacking, electrical checkout, and prop load.

FALCON 9

The next SpaceX Falcon 9 rocket from Cape Canaveral will launch the sixteenth batch of Starlink satellites on November 21 at 10:17pm EST. A Falcon 9 will launch the first cargo Dragon 2 to the ISS, CRS-21, from pad 39A on December 2 at 12:50pm EST. The launch time gets 22-26 min. earlier each day. Other upcoming Falcon 9 launches are TBA. A Falcon 9 will launch NROL-108 for the National Reconnaissance Office from pad 40 on TBD. The first stage will land back at the Cape about eight minutes after launch. A Falcon 9 will launch the SiriusXM-7 communications satellite from pad 40 on December TBD, likely in the middle of the night EST. A Falcon 9 will launch the Turksat 5A communication satellite on December TBD. And a Falcon 9 will launch a smallsat rideshare mission into polar orbit on late December TBD. The first stage should land back at the Cape around eight minutes after launch.

An interesting development: use of an over-5-flights reused booster for a commercial payload (e.g. not Starlink).  Not an unexpected development; SpaceX must do so sooner or later.  Best wishes to them.

Many GTO launches around the world launch during local time overnight hours.  I know (from NSF) that GTO launch times are driven by optimizing launch time to get sunlight generating electricity from just-unfolded solar panels as soon as possible.

What is different with this launch?  Is it because we're near December solstice?

If successful, the number of flights 1051 will have made this calendar year will equal the total number of Atlas V flights during the same timeframe.

Not all spacecraft launched to GTO have that same requirement. Sometimes launch time is also driven by other more intricate constraints such as the timezone of where the first ground station is gonna get telemetry from the satellite. Some of them don't even care about the sunlight recieved after separation since they have plenty of onboard battery life to survive hours in the shadow. Reducing every single GTO satellite into one kind of satellite isn't the best thing to do IMO but news sites and similar places keep repeating the thing about the solar panels needing to get sunlight ASAP when that can only be applied to a fraction of all the GTO sats.

Also doesn't hurt upper stage thermal loads if the geometry of the ascent keeps it mostly in the earth's shadow during the coast phase.

GTO coast phase is usually just to reach the equator, usually less than 30. thermals are a bigger problem for GSO or MEO circular orbits.

NROL-44 is now scheduled for the evening of December 10, so that seems likely to delay SXM-7. Not sure how much time the range needs between the two launches.
