It is a signal at 11729 on AMC9. LEO-1 is the network name it comes up with. It usually just has color bars on it.Forgive my ignorance. What is this LEO-1 everyone keeps writing about. Is this part of 83.0W°? What frequency is it? Or is it a siganl from a close satellite to AMC 9?

Receivers that have trouble with locking on RTN often seem to lock on this signal instead of the nearby 11735 RTN signal. There is actually another signal to just lower than 11729 too. My complete wild guess is that depending on the size of freq tuning steps in receivers, they may tend to skip over the RTN signal if the LEO signal is bigger. Usually the two signals are about the same strength.
Are they watchable at that level? On my Mercury II, anything below ~45% pixels out.I am showing a quality level of ~36% (jumping between 33% and 41% - I wish the meter was a little more stable than this, I will eventually get use to it I am sure, just takes some time).

Working in the rain here on my Pansat. Must be some receivers don't want to be RTN friendly.
TvroPro,
There is definitely a difference. I bought a few Pansat 2700A models. My brother is using them now and he can get the RTN channels, but never picks up the Video-1 channel. The Coolsat only wants to see the Video-1 channel and won't pick up the RTNs. The Dynamic picks up all of them! That of course is our results here near Omaha, NE and using the same equipment for the dish and the LNBF.
This also seems to vary with the weather/time of day here and at the uplink station.
I think that for some locations, RTN must just be so borderline that it can't hold its muster.

RTN was having minor break up for me yesterday, but its back up about 7-8 Q points on my Visionsat today. That was the first time I've experienced breakup on RTN...
Here is a trick to get the RTN channels to come in if you are having trouble with it.
Thanks go to Walrus1957!
I did this with my Coolsat 5K.
Go to MANUAL SCAN mode and select TP 11.735 H polarity.
Then EDIT the SYMBOL RATE by increasing it by 10 MS/s at a time.
If the interference from LEO-1 is what is causing your problems, you will increase the SR until LEO-1 unlocks. This may be upwards near 4.610 MS/s. You cannot go too high with this otherwise you will also lose the RTN signal lock, there is a limit which appears to be near 4.650 MS/s for the Coolsat 5K. Once the signal from LEO-1 unlocks its grip, you should be able to let the receiver sit idle in the MANUAL SCAN mode until the RTN signal locks on.
If the signal power from RTN is weak in your location, it may require you to wait for it to lock on. We were detecting approximately 70% signal quality on (the Coolsat 5Ks meter) with both a 76 cm and a 1.2 M dish with an Invacom QPH-031 LNBF.
Once the RTN signal finds a lock, then you can press OK to scan and both RTN channels should be found and remain locked.
Basically LEO-1 has a lower SR than RTN, so you want to set the range of the SR window high enough to cancel LEO-1 but still allow RTN.
Tested this on two unique Coolsat 5Ks in different locations and it worked fine. After it locks on to the RTN signal, it is hard to get it to unlock.
This worked for these Coolsat receivers, but the same theory should apply to other receivers as well, with possibly different SR settings.
