I went through all my transponder and spot beam strengths on the new meter (Dish 500 on 110/119 and 30-inch Dish on 129) and based on 10 years experience, and having checked the numbers yesterday with the old meter, here is my take on how to interpret the new numbers:
0-10 Currently losing signal (this from Dish documentation)
10-20 ? (will need to fill this in later during a storm)
20-30 ? (will need to fill this in later during a storm)
30-40 A probably cause of signal loss in a storm
40-50 Okay in light storm, a problem in a strong storm
50-60 Probably fine except in the strongest storms
60 and above Unlikely to lose signal
100 and above A spot beam is pointed right at you
NOTE: "Storms" refers to weather events that cause satellite signal loss, and refers to severity in terms of dish reception, which usually means water content in the air between you and the satellite. You could have weather that seems severe in other aspects that doesn't affect the dish signal, while some otherwise innocuous rain event knocks out the channel you are watching...
PS We have other threads about how customers will be confused by the new meter, please don't clutter up this thread (which is about what the numbers mean) with more whining.
