[ldm-users] Those with direct satellite feeds of NOAAport...

All others disregard and all replies offline, please...

I get about 20-30 of these per day in my ldmd.log:

And yet, my signal levels seem to be fine; variable bit error rate is 
mostly zero and never above 3 x 10(-7). I'm using a 3.6 m (12') dish, 
using a Norsat 3120 LNB, and a Novra box as a decoder. Signal strength is 
78.

I compare my feed:

With LSU's:

They are very slightly different, flipping back and forth between the two 
using Internet Explorer 7, in the number of products received; I seem to 
miss a few here and there. Does anyone lose data...

1. When it rains?
2. When it is windy?

Our rusty struts on our LNB will be replaced soon; it tends to vibrate 
slightly when the wind is over 40 MPH.

I don't notice any data loss, so it isn't very significant...but I want 
perfect reception, even in heavy rain.
