[aprssig] [APRS] LightSquared GPS Interference Issue Flares Again in Senators' Letter

[Bob Bruninga]

The key to this is simple SPECTRUM PLANNING!

It was NOT their spectrum!  It was a satellite RECEIVE only band.  Then the
stupid FCC with its Lawyers and INFINITE lack of RF knowledge granted
LightSquared a WAIVER to operate TRANSMITTERS in a RX only band.

DUH!  It is not the receiver's fault.  That is why we have SPECTRUM
PLANNING, so that one does not place high power transmitters in bands
ADJACENT to weak signal receivers.

Aren't there any RF engineers left at the FCC?
