My question/complaint level is exceeded. Time to do 
something to reduce these questions. Lets hack this to so 
it can be used. This proposal is a total hack to report 
signal strength. 

If we have FE_LOCK return a signal strength of say 42 or 100 
or 0x7FFF or 0xFFFF (pick one) otherwise return 0. This 
will allow applications to use signal strength to determine 
if the ATSC/QAM receiver has acquired a signal. Signal 
strength will return either 0 or whatever was picked and 
not the actual signal strength. This hack is not so good 
for antenna aiming.

Humm, if this is a settable parameter, the user could pick 
any return value for the FE_LOCK condition. This would be 
the maximum value that can be returned. This is the "100%" 
value for signal strength.
