My D-11 beeps. Crappy way to get fined tuned for the peak though. Hook up a tv set and take it out to your dish. Watch the numbers for max. After you do that toss a wet rag over the lnb and peak it as high as you get it. This will allow even greater fine tuning. I re did my dish the other day like that 96-100 on everything. It rained this morning I lost 1 point during the rain that's it.
