Weaker signal at night?

[Chapin]

I am using a 1.2 meter dish from Guatemala to receive DTV. I get great reception during the late morning to mid afternoon. From then on I loose the signal on some channels, mostly HBO and Cinemax. I have a subscribed card, so that is not the problem. Any suggestions?

I am in a fringe area (Guatremala). I have used a signal strenth meter to optimize the alignment. Is there any way to tell what transponders relate to what channels? I replaced the lnb and that helped a lot.

I'm in north central British Columbia and ever since the new bird went on line 13 months ago and the even transponders were switched to it signal strength (even only, odds run in the 90's) is a problem. Using a 1 meter channelmaster every fourth transponder is 0 strength. The others range from mid 60's in the day to low 40's late at night.(below 40 my hughes starts crapping out - at 35 its gone) Sometimes more of the evens will drop off, weather sure can do it but a few have gone when the night is clear also.
Somewhere in the last few weeks there was an article about the satellites and how when they are in the dark - cold and not charging - the broadcast power is reduced while its heaters are drawing power. I'm no sat wizard but that can answer the signal dropping at night, every night.
I've tried inline boosters from Rat Shack and both cost signal strength no matter where I put them. Line run is less than 50 feet. Dish aligned with a set right there to adjust so its as bang on as could be - sighting on an even transponder.
The only answer appears to be a bigger dish, or going without the missing channels. On the bright side 99% of the sports and ppv's are on the odds.
250 miles west and a bit north of here an 18inch dish works - I'm guessing that some signal is focused towards Alaska.

Thanks guys, I have a 1.8 meter dish on order. I changed out my lnb and it helped somewhat.

There is no replacement for displacement, a bigger dish should be the answer.
