I finally bought a used 9241 and 3100 for use at my cottage. I also bought the switch and power inverter from this guy. I made sure both were working on a feed at my home. Then hooked them up at the cottage. I was getting a 90% or better green signal. But when I did the switch check I received a reception error.
Long story short. It seems I lose my programming in the evening. What gives? Thanks as always to anyone with advice.

You may have a bad connection somewhere that's expanding in the daytime and contracting at night, or maybe moisture is getting into it, freezing, etc.

Bell equipment is very touchy about the copper wire in the coax cables. If the copper wire is only flush with the collar, it often makes a poor connection. It should extend about a quarter inch beyond the collar.

Sorry, I should have been more specific. ALL the programming is gone the next day, as if I don't subscribe to anything (pink/red colour).

And they work at home.?

Do you run a "Check Switch" at the Cottage.?

Pinza, yes, I do the check switch at the cottage.

Yes, they work at home.

My guess would be that Bell doesn't want you getting service at the cottage if you are only paying for Satellite TV for one account at home. I could be wrong and you might have a 2nd account you are paying for at your cottage, in which case you should definately be getting service there as well.

Please tell me that you DO NOT have the phone line plugged in at both locations..

It's one account, which they shouldn't have a problem with. As far as I understand this is allowed.
And no, neither is connected to a phone line for that matter. I don't order ppv.

Sounds like there is a difference between the two setups. You could be using different lnb's, possibly the wrong switch, bad cabling, mixed up connections from the lnb's to the switch.
There is no practicle way Bell could distinguish between your home install or a remote install unless you tell them - either with a phone line or telling them your location IDs.
Assuming you are using legacy lnb's connection to the sw-44 should be Sat A , Sat A, Sat B, Sat B. Just double check you didn't get one or more of the cables crossed from the lnb's down lnb arm.
The receiver will keep the last known checkswitch data until you perform another checkswitch. Sounds like when you ran a checkswitch at the cottage something was not right as you got a reception error.
