[amsat-bb] Re: Icom 910H vs Kenwood TS2000

[w4upd]

I am amazed at how many people take things stated out of context on this 
reflector. I never said that any of the arrays would not work due to 
being too narrow for satellite work. An individual asked about the 
problem they were having hearing the satellites and it was stated that 
if none of the other suggestions worked to consider that the arrays they 
are using are pointed correctly in the correct direction of the 
satellite. Pointing being off, the nulls could easily block the 
satellite's reception. The larger the array the more this might be 
evident. The larger the array, stacked arrays and even dish antennas, 
pointing becomes a bit more critical.
