[time-nuts] GPS Interference Question

[jmfranke]

There are several problems. First energy from the offending signal leaking 
into the protected GPS band and second the GPS receivers having a bandwidth 
greater than the protected GPS band in order to reduce phase errors, acquire 
GPS signal energy present outside the protected GPS band to have a higher 
bandwidth signal, and to reduce production costs. The GPS industry is part 
of the problem.

I firmly believe the protected band needs to be increased. I will always 
favor better time and frequency dissemination over social networking.
