Todd and David,

I'm not certain the problem has been fixed. I'm seeing a spike on the 
space frequency right now that's strong enough to mess up decode of 
$04E, Savannah, GA, a very strong night time signal. It's possible this 
is just the result of two big stations sending at the same time (heaven 
knows the 10 minute transmit windows aren't generally adhered to), but 
the spectrum I see looks more like one correct Navtex signal and a very 
strong bogus line at the space frequency. I saw similar behavior briefly 
earlier in the evening too.

A technician replacing a part after two or more days of failure on a 
life/property service isn't acceptable, nor is the lack of a clear way 
to report problems. How can the service people not know when their 
transmitter is transmitting and when it's truly off?
