First time poster, long time reader. Great forum guys and gals!

Anyways I apologize if my receiver is a cheap chinese receiver in advance but I have a GeoSatPro MicroHD that has been in place about 3 years and its been my favaorite receiver I've owned. Previously had a SD Traxis which was great but then came HD and the HD Traxis was not so great.

I realized last night I may be due for an upgrade. I wanted to watch the Hockey on SES3 and I understand it was an S2 feed. I believe the MicroHD is supposed to pick up S2 feeds but all I could get for signal quality on that TP was 10%. CoziTV, and the other NBC channels seemed to come in fine.

Could this be my MicroHD receiver? Does anyone else have experience with this receiver not being great at picking up S2 feeds? Or maybe its time to swap out my LNB for a new one (8 years old)? Any suggestions on a good new STB receiver that can pick up as many KU channels as possible? Preferrably college hockey games!

Yeah I'm one of those few die-hard North Dakota Fighting Sioux hockey fans that bought a KU setup only to be let down by the school selling out to the local cable company who still uplinks but scrambles now!

You need to explain some details of your antenna setup. Size, fixed / motorised, etc.

Your issue is more likely to be related to your antenna / alignment than the receiver.
The Permanent NBC feeds are pretty stout signals, while the temporary wild feeds of an event
originating from an uplink truck are typically a bit weaker. For example, on my fixed primestar antenna on any given clear day, I have ~ 13 to 13.5 dB SNR on the two permanent NBC feeds you mention (minimum for those is 9.5 dB). The Hockey game yesterday, was coming in at about 10 dB SNR, only
1/2 a dB of margin. Though I didn't notice any issues, since I was safely above the reception threshold.. Not by a lot, but good enough...
When I checked the spectrum via an independent source such as https://satsignature.com/plot/america/ses-3

Last night I could see that the signal the hockey game was on, was at least 3 dB less in strength than the two permanent feeds. Accounts for most if not all of the signal quality delta I was seeing.
So, If I was barely receiving the two Perm NBC feeds currently, there is no way I would expect to receive the backhaul feed of the event.

Thanks guys.

I have a 90cm hot dish I believe. It's motorized and likely out of alignment slightly. Maybe I can find some time this summer to tune her up!

Tonight's NHL feed is another I can only get 10% blips on. I'm getting everything else on ses3 as far as I can tell. Handful of nbc channels, RT, nhk, evine, and some Arnold Schwarzenegger competition. I also get in the 4 channel NBC mux that's in s2 at about 10%. These ones actually scan in just are mostly pixelated.

Ignore the vertical for a minute, none there are S2...

the 4 channel mux, 11855 H 4600 is 3/4 FEC, so it has more error correction than the 5/6 FEC feeds do.
S2 8PSK FEC 3/4  - Min 7.9 dB
S2 8PSK FEC 5/6  - Min 9.4 dB
Net effect is 3/4 is easier to receive than 5/6
As HN would say, your issue is in the yard.
Further I would 2nd the motion relative to stamped steel dish..
Played with one of those for a friend once, was barely useful for the strongest NBC feeds.
He eventually replaced it with a 1.2m Channel Master.

Fellow Members, your posts are welcome here! Do not worry about posting everything perfect. Different receivers and LNB's will give you different Frequencies and Symbol Rates. Some set top boxes, PCI cards and USB receivers, Do Not Require all of the same information that others may need. It is not Required to post everything that others may need to tune in a feed. It is just most important to share the find. We can always adjust the Frequency and Symbol Rates and try the various Modulations and FEC's on our own receivers until we get a lock and then give a polite reply with what works for your receiver, as that information might help others as well. We all appreciate the efforts and energy of the Posters!
