[EAS] NWS/CG Interference in NY area

[Phil Johnson]

MM,

1.  I'd be happy to read the WSJ story if someone would supply a link to it.
2.  You didn't address possible intermodulation due to antenna system
degradation.
3.  You didn't address possible transmitter/receiver configuration issues
4.  You assume marine VHF transceivers are badly designed, but you cite no
evidence..
5.  I've never heard of this problem arising anywhere else in the U.S.  
6.  NTIA (a bureaucracy of the National Dept. of Commerce) isn't going to
solve this problem.  USCG and NWS technicians will do it.  I suspect they're
not being allowed to work together effectively.  Otherwise, it wouldn't have
taken since July 2013 to get this far.

Read the Wall Street Journal story from which this story was
plagiarized.There is more info on how both the USCG and NWS are working with
NTIA to solve the problem. In the means time, NWS is in a work around
arrangement of only powering the TX on for warnings.

Now...with that said, I can't image how a 25Khz voice grade audio is
impacting systems 6Mhz. away. There are systems co-located on the same
building 50Khz spaced and there are no problems in the LMR world. Are marine
receivers so wide their front ends overload at such a low level?  
What kind of crapola transceivers are marketed for maritime/marine
operations?
