[amsat-bb] D-Star Interference to XW-2A Downlink

[Paul Stoetzer]

XW-2A is the offender here as it operates outside the 200 kHz
allocated in the bandplan for satellites, so there isn't any recourse.
The satellite portion of the bandplan is 145.800 - 146.000 MHz (though
amateur satellite transmissions are legal from 144 MHz - 146 MHz).

Note that the Texas VHF-FM Society Bandplan establishes 145.500 MHz -
145.800 MHz for simplex or experimental use
