[Heathkit] GC-1000 decrease rx sensitivity

[CLIFF WALLACE]

Greetings listers,
                  Have noted that my "most accurate
clock" seems to be lacking sensitivity and sometimes
takes days to synch-up, where it used to do it in a
couple of hours.  Nothing has changed and it is still
on the inside antenna as it has been for years. 
Before I tear into it and check all the obvious
things, thought I would run it up the flagpole and see
if anyone's had a similar problem and what they found.
 I also have 2 other time sources on inside antennas
and they are A-1, so I must discount a WWV signal
problem.  

Thanks in advance,
                  Cliff
