Cold

I am having a problem with my c band side on my mini bud at night. During the day when its abut 45 degrees out just fine. When its closer to freezing point I lose krbk and 20 percent of pr vi mux and video drags it goes from 72 percent to 55 to 60q yesterday it was nice until night time. I have changed wiring, lnbfs, same thing happens, ku lnbs they are doing just fine. Any ideas?

Being a microBUD, everything will be super critical as there's not much headroom in the signal dept. Shrinkage/expansion of the dish and LNBF supports is all that I can think of.
Even on my steel BUD I do notice, only slightly, a daily up/down in the Q on some channels.

I agree. When I had a 6ft dish cband would do similar things at night. With the 10ft same lnbf , wiring, pole and motor its solid. Sorry I cant be of more help.

I had a bad LNBF causing me to lose signals at or below freezing.

Danristheman has swapped LNBFs, cables connectors. His challenge still exists. Likely as Fat Air suggests. a microBUD has little or no margin. The smallest change in the atmosphere, dish and feedhorn efficiency will bring the signal below threshold.

I've been quite impressed what Dan has achieved with his minibud dish! About 7 years ago, I had one setup on 91 when FMC was in the clear. I remember not getting the CW channels for four months or so. Then, they popped in sometime in April. The receiver plays a big part also. In two years, I never got a picture of FMC with a Pansat 1500 or Coolsat 5000. However, my Viewsat and CNX boxes had no problem. Time of year/Dish size/Receiver (tuner) all play a part in Mini-Budding.

and location too (how well you are within the footprint)

Agreed, most important. Remember all of Walrus 52 posts? He was in a great footprint and spearheaded the Mini-bud fascination.
