Incoming President Requests DTV Cutover Delay

[Will Russell]

Also, there is a question of the sensitivity of the converters (and  
the receivers in the DTV receivers).  Assuming  there are standards it  
would seem that the various designs would perform differently.

My recollection is that a member talked about testing these devices  
last summer.  If that person reads this could he or she respond with  
whether the tests covered the performance of the units and if so what  
data was obtained?  Another possibility is that performance data is  
available on line.  Any links?

Thanks.
