This is what I got ;

ntpq -i
Name or service not known
ntpq> debug more
debug level set to 1
ntpq> peers
***No host open, use `host' command
ntpq> host 198.82.1.203
current host set to 198.82.1.203
ntpq> peers
198.82.1.203: timed out, nothing received
***Request timed out
ntpq> debug more
debug level set to 2
ntpq> peers
198.82.1.203: timed out, nothing received
***Request timed out
ntpq>

I'm not sure I'm using this right but it seems not matter what I try 
ntpq does nothing
and it always worked in the past.  At first I thought it might be due to 
the round trip transit time
between here and the satellite which probably add a quarter of a 
second?  But it seems to me that
I've seen some long delays in the ntpq data at times although that's not 
typical, normally more like
.160 [s/ms?].
